Carte de l'Afrique


Africa is the world's second-largest and second most-populous continent, after Asia. At about 30.2 million km² (11.7 million sq mi) including adjacent islands, it covers 6% of the Earth's total surface area and 20.4% of the total land area. With a billion people in 61 territories, it accounts for about 14.72% of the World's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent has 54 states, including Madagascar, various island groups, and the Sahrawi Arab Democratic Republic, a member state of the African Union whose statehood is disputed by Morocco.
Africa, particularly central eastern Africa, is widely regarded within the scientific community to be the origin of humans and the Hominidae clade , as evidenced by the discovery of the earliest hominids and their ancestors, as well as later ones that have been dated to around seven million years ago – including Sahelanthropus tchadensis, Australopithecus africanus, A. afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens found in Ethiopia being dated to ca. 200,000 years ago.
Africa straddles the equator and encompasses numerous climate areas; it is the only continent to stretch from the northern temperate to southern temperate zones.
At the beginning of the Mesozoic Era, Africa was joined with Earth's other continents in Pangaea. Africa shared the supercontinent's relatively uniform fauna which was dominated by theropods, prosauropods and primitive ornithischians by the close of the Triassic period. Late Triassic fossils are found through-out Africa, but are more common in the south than north. The boundary separating the Triassic and Jurassic marks the advent of an extinction event with global impact, although African strata from this time period have not been thoroughly studied.
Early Jurassic strata are distributed in a similar fashion to Late Triassic beds, with more common outcrops in the south and less common fossil beds which are predominated by tracks to the north. As the Jurassic proceeded, larger and more iconic groups of dinosaurs like sauropods and ornithopods proliferated in Africa. Middle Jurassic strata are neither well represented nor well studied in Africa. Late Jurassic strata are also poorly represented apart from the spectacular Tendaguru fauna in Tanzania. The Late Jurassic life of Tendaguru is very similar to that found in western North America's Morrison Formation.
Midway through the Mesozoic, about 150–160 million years ago, Madagascar separated from Africa, although it remained connected to India and the rest of the Gondwanan landmasses.Fossils from Madagascar include abelisaurs and titanosaurs.

Later into the Early Cretaceous epoch, the India-Madagascar landmass separated from the rest of Gondwana. By the Late Cretaceous, Madagascar and India had permanently split ways and continued until later reaching their modern configurations.
By contrast to Madagascar, mainland Africa was relatively stable in position through-out the Mesozoic. Despite the stable position, major changes occurred to its relation to other landmasses as the remains of Pangea continued to break apart. By the beginning of the Late Cretaceous epoch South America had split off from Africa, completing the southern half of the Atlantic Ocean. This event had a profound effect on global climate by altering ocean currents.
During the Cretaceous, Africa was populated by allosauroids and spinosaurids, including the largest known carnivorous dinosaurs. Titanosaurs were significant herbivores in its ancient ecosystems. Cretaceous sites are more common than Jurassic ones, but are often unable to be dated radiometrically making it difficult to know their exact ages. Paleontologist Louis Jacobs, who spent time doing field work in Malawi, says that African beds are "in need of more field work" and will prove to be a "fertile ground ... for discovery."
Africa is considered by most paleoanthropologists to be the oldest inhabited territory on Earth, with the human species originating from the continent. During the middle of the twentieth century, anthropologists discovered many fossils and evidence of human occupation perhaps as early as 7 million years ago. Fossil remains of several species of early apelike humans thought to have evolved into modern man, such as Australopithecus afarensis (radiometrically dated to approximately 3.9–3.0 million years BC), Paranthropus boisei (c. 2.3–1.4 million years BC) and Homo ergaster (c. 1.9 million–600,000 years BC) have been discovered.
Throughout humanity's prehistory, Africa had no nation states, and was instead inhabited by groups of hunter-gatherers such as the Khoi and San.
At the end of the Ice Ages, estimated to have been around 10,500 BC, the Sahara had again become a green fertile valley, and its African populations returned from the interior and coastal highlands in Sub-Saharan Africa[citation needed]. However, the warming and drying climate meant that by 5000 BC the Sahara region was becoming increasingly dry and hostile. The population trekked out of the Sahara region towards the Nile Valley below the Second Cataract where they made permanent or semi-permanent settlements. A major climatic recession occurred, lessening the heavy and persistent rains in Central and Eastern Africa. Since this time dry conditions have prevailed in Eastern Africa, and increasingly during the last 200 years, in Ethiopia.
The domestication of cattle in Africa preceded agriculture and seems to have existed alongside hunter-gathering cultures. It is speculated that by 6000 BC cattle were already domesticated in North Africa. In the Sahara-Nile complex, people domesticated many animals including the donkey, and a small screw-horned goat which was common from Algeria to Nubia. In the year 4000 BC the climate of the Sahara started to become drier at an exceedingly fast pace. This climate change caused lakes and rivers to shrink significantly and caused increasing desertification. This, in turn, decreased the amount of land conducive to settlements and helped to cause migrations of farming communities to the more tropical climate of West Africa.
By the first millennium BC ironworking had been introduced in Northern Africa and quickly spread across the Sahara into the northern parts of sub-Saharan Africa and by 500 BC metalworking began to become commonplace in West Africa. Ironworking was fully established by roughly 500 BC in many areas of East and West Africa, although other regions didn't begin ironworking until the early centuries AD. Copper objects from Egypt, North Africa, Nubia and Ethiopia dating from around 500 BC have been excavated in West Africa, suggesting that trans-saharan trade networks had been established by this date.

Africa is the largest of the three great southward projections from the largest landmass of the Earth. Separated from Europe by the Mediterranean Sea, it is joined to Asia at its northeast extremity by the Isthmus of Suez , 163 km (101 miles) wide. From the most northerly point, Ras ben Sakka in Tunisia (37°21' N), to the most southerly point, Cape Agulhas in South Africa (34°51'15" S), is a distance of approximately 8,000 km (5,000 miles);[48] from Cape Verde, 17°33'22" W, the westernmost point, to Ras Hafun in Somalia, 51°27'52" E, the most easterly projection, is a distance of approximately 7,400 km (4,600 miles). The coastline is 26,000 km (16,100 miles) long, and the absence of deep indentations of the shore is illustrated by the fact that Europe, which covers only 10,400,000 km² (4,010,000 square miles) – about a third of the surface of Africa – has a coastline of 32,000 km (19,800 miles).
Africa's largest country is Sudan, and its smallest country is the Seychelles, an archipelago off the east coast.The smallest nation on the continental mainland is The Gambia.

According to the ancient Romans, Africa lay to the west of Egypt, while "Asia" was used to refer to Anatolia and lands to the east. A definite line was drawn between the two continents by the geographer Ptolemy (85–165 AD), indicating Alexandria along the Prime Meridian and making the isthmus of Suez and the Red Sea the boundary between Asia and Africa. As Europeans came to understand the real extent of the continent, the idea of Africa expanded with their knowledge.
Geologically, Africa includes the Arabian Peninsula; the Zagros Mountains of Iran and the Anatolian Plateau of Turkey mark where the African Plate collided with Eurasia. The Afrotropic ecozone and the Saharo-Arabian desert to its north unite the region biogeographically, and the Afro-Asiatic language family unites the north linguistically.

The Strait of Gibraltar

The Strait of Gibraltar is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Spain from Morocco. The name comes from Gibraltar, which in turn originates from the Arabic Jebel Tariq , albeit the Arab name for the Strait is Bab el-Zakat or "Gate of Charity". It is also erroneously known as the Straits of Gibraltar, in naval use and as "Pillars of Hercules" in the ancient world.
Europe and Africa are separated by 7.7 nautical miles (14.24 km) of ocean at the strait's narrowest point. The Strait's depth ranges between 300 and 900 metres (980 and 3,000 ft) which possibly interacted with the lower mean sea level of the last major glaciation 20,000 years before present when the level of the sea was believed to be 110 to 120 metres (361 to 394 ft) lower. Ferries cross between the two continents every day in as little as 35 minutes. The Spanish side of the Strait is protected under El Estrecho Natural Park.
Around 5.9 million years ago, the connection between the Mediterranean Sea and the Atlantic Ocean along the Bethic and Rifan Corridor was progressively restricted until its total closure, effectively causing the salinity of the Mediterranean to periodically fall within the gypsum and salt deposition range, during what is known as the Messinian Salinity Crisis. In this water chemistry environment, dissolved mineral concentrations, temperature and stilled water currents combined properly and occurred regularly to precipitate many mineral salts in sea floor bedded layers. The resultant accumulation of various huge salt and mineral deposits about the Mediterranean basin are directly linked to this era. It is not believed this process took a long time geologically, lasting only 500-600 thousand-years, for it is further estimated that were the straits closed even at today's higher sea level, most water in the Mediterranean basin would evaporate within only a thousand years; as it is believed to have done then, and such an event would lay down similar mineral deposits as those such as the fabulous salt mines now found under the sea floor off Sicily. After a lengthy period of restricted intermittent or no water exchange between the Atlantic Ocean and Mediterranean basin, approximately 5.33 million years ago, the Atlantic-Mediterranean connection was completely reestablished through the Strait of Gibraltar, and has remained open ever since. It is expected that the strait will close again as the African Plate moves northward relative to the Eurasian Plate[citation needed], but on geological rather than human timescales.

Through the strait, water generally flows more or less continually in both an eastward and a westward direction. A smaller amount of deeper saltier and therefore denser waters continually work their way westwards , while a larger amount of surface waters with lower salinity and density continually work their way eastwards . These general flow tendencies may be occasionally interrupted for brief periods to accommodate temporary tidal flow requirements, depending on various lunar and solar alignments. Still, on the whole and over time, the balance of the water flow is eastwards, due to an evaporation rate within the Mediterranean basin higher than the combined inflow of all the rivers that empty into it. The shallow Camarinal Sill of the Strait of Gibraltar, which forms the shallowest point within the strait, acts to limit mixing between the cold, less saline Atlantic water and the warm Mediterranean waters. The Camarinal Sill is located at the far western end of the straits.
The Mediterranean waters are so much saltier than the Atlantic waters, that they sink below the constantly incoming water and form a highly saline layer of bottom water. This layer of bottom-water constantly works its way out into the Atlantic as the Mediterranean outflow. On the Atlantic side of the strait, a density boundary separates the Mediterranean outflow waters from the rest at about 100 metres (330 ft) depth. These waters flow out and down the continental slope, losing salinity, until they begin to mix and equilibrate more rapidly, much further out at a depth of about 1,000 metres (3,300 ft). The Mediterranean outflow water layer can be traced for thousands of kilometres west of the strait, before completely losing its identity.
Internal waves are often produced by the strait. Like traffic merging on a highway, the water flow is constricted in both directions because it must pass over a shallow submarine barrier, the Camarinal Sill. When large tidal flows enter the Strait and the high tide relaxes, internal waves are generated at the Camarinal Sill and proceed eastwards. Even though the waves may occur down to great depths, occasionally at the surface the waves are almost imperceptible, at other times they can be seen clearly using satellite imagery. These internal waves continue to flow eastward and to refract around coastal features. They can sometimes be traced for as much as 100 kilometres (62 mi), and sometimes create interference patterns with refracted waves.

Oran is a major city on the Mediterranean coast in northwestern Algeria. The name comes from the Berber word Uhran meaning The Lions.
During French rule, Oran was a prefecture in the Oran département. It is now the capital of the smaller Oran Province . The city has a population of 683,250 , while the metropolitan area has a population of approximately 2 million, making it the second largest city in Algeria. Oran is a major port, and since the 1960s has been the commercial, industrial, and educational centre of western Algeria.
Oran was founded in 903 by Moorish Andalusi traders but was captured by the Spanish under Cardinal Cisneros in 1509. Spanish sovereignty lasted until 1708, when the city was conquered by the Ottomans. Spain recaptured the city in 1732. However, its value as a trading post had decreased greatly, so King Charles IV sold the city to the Turks in 1792. Ottoman rule lasted until 1831, when it fell to the French.
During French rule over Algeria, Oran was the capital of a département of the same name . In July 1940, the British navy shelled French warships in the port after they refused a British ultimatum designed to ensure they would not fall into German hands. The action increased the hatred of the Vichy regime for Britain but convinced the world of the British will to fight on alone against Nazi Germany and its allies. The puppet Vichy government held Oran during World War II until its capture by the Allies in late 1942, during Operation Torch.
Before the Algerian War, 1954–1962, Oran had one of the highest proportions of Europeans of any city in North Africa. However, shortly after the end of the war, most of the Europeans and Sephardic Jews living in Oran fled to France. A massacre of Europeans, four days after the vote for Algerian independence, triggered the exodus to France. In less than three months Oran lost about half its population.

Before the Spaniards, the Portuguese launched a failed expedition to capture the city in July 1501. Four years later, the Spanish took Mers-el-Kébir, located just four miles to the west of the Oran. Thus began the first organized incursions against the city which, at the time, numbered 25,000 inhabitants and counted 6,000 fueros. Count Pedro Navarro, on the orders of Cardinal Francisco Jiménez de Cisneros, captured the city on May 17, 1509.
By 1554, the Turks had reach Algiers, and then governor of Oran, Count d'Alcaudete, allied himself with Moroccan Sultan Mohammed ash-Sheikh against them. Nine years later, in 1563, Álvaro de Bazán, Marquis de Santa Cruz, built the fort of Santa-Cruz, strategically placed at the top of a mountain, l'Aïdour, more than 1,000' above the sea, directly to the west of the city. Pedro Garcerán de Borja, Grand Master of the Order of Montesa, was captain of Oran when, on July 14, 1568, John of Austria , led a flotilla of 33 galleys against the Algerians.
The Spanish rebuilt the fortress of Santa Cruz to accommodate their city governors. "The fortifications of the place were composed of thick and continuous walls of over two and a half kilometers in circumference, surmounted by strong towers spaced between them," with a central castle or kasbah where the Spanish governor established his headquarters. The city under Spanish rule continued to grow, requiring enlargement of the city walls. In spite of the improved fortifications, the city was the object of repeated attacks. Notable in this regard, Moroccan Sharif Moulay Ismail tried to force his way past the defenses in 1707, only to see his army decimated.
The Spaniards occupied the city until 1708, when they were driven out by Turkish Bey Mustapha Ben Youssef . The Spanish returned in 1732 when the armada of the Duke of Montemar was victorious in the Battle of Aïn-el-Turk.
In the night after October 8, 1790, a violent earthquake claimed more than 3,000 victims in less than seven minutes. Thereafter Charles IV saw no advantage in continuing the occupation of the city, which had become increasingly expensive and perilous. He initiated discussions with the Bey of Algiers. A treaty handing over the city was signed on September 12, 1792. After another earthquake had damaged the Spanish defences, Bey Ben Othman's forces took possession of Oran on October 8 of the same year. In 1796, the Pasha Mosque (in honour of Hassan Pasha, Dey of Algeria), was built by the Turks with ransom money paid for the release of Spanish prisoners after Spain's final departure. In 1830 the Beys moved their capital from Mascara to Oran.
The town of 10,000 inhabitants was still in the possession of the Ottoman Empire, when a squadron under the command of captain Bourmand seized el-Kébir on December 14, 1830. The city was in a wretched state. On January 4, 1831, the French commanded by General Denys de Damrémont occupied Oran. In September 1830 the King appointed a police chief with the function of mayor in Algiers. In September 1831, General Berthezène made Mr. Pujol, captain of cavalry in retirement and wounded at the right hand under the Empire, mayor of Oran. In 1832, at the head of five thousand men, a young Emir called Abd al-Qadir attacks Oran. In April 1833, commander-in-chief, General Boyer, leaves Oran and is replaced by the baron Louis Alexis Desmichels. The city, attacked by Abd el Kader, holds good.

Algeria officially the People's Democratic Republic of Algeria, is a country located in North Africa. In terms of land area, it is the largest country on the Mediterranean Sea, the second largest on the African continent after Sudan, and the eleventh-largest country in the world.
Algeria is bordered by Tunisia in the northeast, Libya in the east, Niger in the southeast, Mali and Mauritania in the southwest, a few kilometers of the Moroccan-controlled Western Sahara in the southwest, Morocco in the west and northwest, and the Mediterranean Sea in the north. Its size is almost 2,400,000 km2, and it has an estimated population of about 35,700,000 as of January 2010. The capital of Algeria is Algiers.
Algeria is a member of the United Nations, African Union, and OPEC. It also contributed towards the creation of the Maghreb Union.
Algeria comprises 2,381,741 square kilometers of land, more than four-fifths of which is desert, in northern Africa, between Morocco and Tunisia. It is the second largest country in Africa, after Sudan. Its Arabic name, Al Jazair (the islands), derives from the name of the capital Algiers (Al Jazair in Arabic), after the small islands formerly found in its harbor. It has a long Mediterranean coastline. The northern portion, an area of mountains, valleys, and plateaus between the Mediterranean Sea and the Sahara Desert, forms an integral part of the section of North Africa known as the Maghreb. This area includes Morocco, Tunisia, and the northwestern portion of Libya known historically as Tripolitania.
Stretching from the Moroccan border the Tell Atlas, including the Djebel Babor formation, is the dominant northwestern mountain range. Stretching more than 600 kilometers eastward from the Moroccan border, the High Plateaus consist of undulating, steppe-like plains lying between the Tell and Saharan Atlas ranges. The plateaus average between 1,100 and 1,300 meters in elevation in the west, dropping to 400 meters in the east. So dry that they are sometimes thought of as part of the Sahara, the plateaus are covered by alluvial debris formed when the mountains eroded. An occasional ridge projects through the alluvial cover to interrupt the monotony of the landscape.
Higher and more continuous than the Tell Atlas, the Sahara Atlas range is formed of three massifs: the Ksour near the Moroccan border, the Amour, and the Oulad Nail south of Algiers. The mountains, which receive more rainfall than those of the High Plateaus, include some good grazing land. Watercourses on the southern slopes of these massifs disappear into the desert but supply the wells of numerous oases along the northern edge of the desert, of which Biskra, Laghouat, and Béchar are the most prominent.
Eastern Algeria consists of a massive area extensively dissected into mountains, plains, and basins. It differs from the western portion of the country in that its prominent topographic features do not parallel the coast. In its southern sector, the steep cliffs and long ridges of the Aurès Mountains create an almost impenetrable refuge that has played an important part in the history of the Maghrib since Roman times. Near the northern coast, the Petite Kabylie Mountains are separated from the Grande Kabylie range at the eastward limits of the Tell by the Soummam River. The coast is predominantly mountainous in the far eastern part of the country, but limited plains provide hinterlands for the port cities of Bejaïa, Skikda, and Annaba. In the interior of the region, extensive high plains mark the region around Sétif and Constantine; these plains were developed during the French colonial period as the principal centers of grain cultivation. Near Constantine, salt marshes offer seasonal grazing grounds to seminomadic sheep herders.
The Sahara
The Algerian portion of the Sahara extends south of the Saharan Atlas for 1,500 kilometers to the Niger and Mali frontiers. The desert is an otherworldly place, scarcely considered an integral part of the country. Far from being covered wholly by sweeps of sand, however, it is a region of great diversity. Immense areas of sand dunes called areg occupy about one-quarter of the territory. The largest such region is the Grand Erg Oriental , where enormous dunes two to five meters high are spaced about 40 meters apart. Much of the remainder of the desert is covered by rocky platforms called humud , and almost the entire southeastern quarter is taken up by the high, complex mass of the Ahaggar and Tassili-n-Ajjer highlands, some parts of which reach more than 2,000 meters. Surrounding the Ahaggar are sandstone plateaus, cut into deep gorges by ancient rivers, and to the west a desert of pebbles stretches to the Mali frontier.
The desert consists of readily distinguishable northern and southern sectors, the northern sector extending southward a little less than half the distance to the Niger and Mali frontiers. The north, less arid than the south, supports most of the few persons who live in the region and contains most of the desert's oases. Sand dunes are the most prominent features of this area's topography, but between the desert areas of the Grand Erg Oriental and the Grand Erg Occidental and extending north to the Atlas Saharien are plateaus, including a complex limestone structure called the M'zab where the M'zabite Berbers have settled. The southern zone of the Sahara is almost totally arid and is inhabited only by the Tuareg nomads and, recently, by oil camp workers. Barren rock predominates, but in some parts of Ahaggar and Tassili-n-Ajjer alluvial deposits permit garden farming.

Ancient Egypt was an ancient civilization of eastern North Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. The civilization coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh, and it developed over the next three millennia. Its history occurred in a series of stable Kingdoms, separated by periods of relative instability known as Intermediate Periods. Ancient Egypt reached its pinnacle during the New Kingdom, after which it entered a period of slow decline. Egypt was conquered by a succession of foreign powers in this late period, and the rule of the pharaohs officially ended in 31 BC when the early Roman Empire conquered Egypt and made it a province.
The success of ancient Egyptian civilization stemmed partly from its ability to adapt to the conditions of the Nile River Valley. The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which fueled social development and culture. With resources to spare, the administration sponsored mineral exploitation of the valley and surrounding desert regions, the early development of an independent writing system, the organization of collective construction and agricultural projects, trade with surrounding regions, and a military intended to defeat foreign enemies and assert Egyptian dominance. Motivating and organizing these activities was a bureaucracy of elite scribes, religious leaders, and administrators under the control of a pharaoh who ensured the cooperation and unity of the Egyptian people in the context of an elaborate system of religious beliefs.
The many achievements of the ancient Egyptians include the quarrying, surveying and construction techniques that facilitated the building of monumental pyramids, temples, and obelisks; a system of mathematics, a practical and effective system of medicine, irrigation systems and agricultural production techniques, the first known ships, Egyptian faience and glass technology, new forms of literature, and the earliest known peace treaty. Egypt left a lasting legacy. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world. Its monumental ruins have inspired the imaginations of travellers and writers for centuries. A newfound respect for antiquities and excavations in the early modern period led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy, for Egypt and the world.

Stunning advances in architecture, art, and technology were made during the Old Kingdom, fueled by the increased agricultural productivity made possible by a well developed central administration. Under the direction of the vizier, state officials collected taxes, coordinated irrigation projects to improve crop yield, drafted peasants to work on construction projects, and established a justice system to maintain peace and order. With the surplus resources made available by a productive and stable economy, the state was able to sponsor construction of colossal monuments and to commission exceptional works of art from the royal workshops. The pyramids built by Djoser, Khufu, and their descendants are the most memorable symbols of ancient Egyptian civilization, and the power of the pharaohs that controlled it.
Along with the rising importance of a central administration arose a new class of educated scribes and officials who were granted estates by the pharaoh in payment for their services. Pharaohs also made land grants to their mortuary cults and local temples to ensure that these institutions would have the necessary resources to worship the pharaoh after his death. By the end of the Old Kingdom, five centuries of these feudal practices had slowly eroded the economic power of the pharaoh, who could no longer afford to support a large centralized administration.[28] As the power of the pharaoh diminished, regional governors called nomarchs began to challenge the supremacy of the pharaoh. This, coupled with severe droughts between 2200 and 2150 BC, ultimately caused the country to enter a 140-year period of famine and strife known as the First Intermediate Period.
The New Kingdom pharaohs established a period of unprecedented prosperity by securing their borders and strengthening diplomatic ties with their neighbors. Military campaigns waged under Tuthmosis I and his grandson Tuthmosis III extended the influence of the pharaohs into Syria and Nubia, cementing loyalties and opening access to critical imports such as bronze and wood.The New Kingdom pharaohs began a large-scale building campaign to promote the god Amun, whose growing cult was based in Karnak. They also constructed monuments to glorify their own achievements, both real and imagined. The female pharaoh Hatshepsut used such propaganda to legitimize her claim to the throne. Her successful reign was marked by trading expeditions to Punt, an elegant mortuary temple, a colossal pair of obelisks and a chapel at Karnak. Despite her achievements, Hatshepsut's nephew-stepson Tuthmosis III sought to erase her legacy near the end of his reign, possibly in retaliation for usurping his throne.

Around 1350 BC, the stability of the New Kingdom was threatened when Amenhotep IV ascended the throne and instituted a series of radical and chaotic reforms. Changing his name to Akhenaten, he touted the previously obscure sun god Aten as the supreme deity, suppressed the worship of other deities, and attacked the power of the priestly establishment. Moving the capital to the new city of Akhetaten , Akhenaten turned a deaf ear to foreign affairs and absorbed himself in his new religion and artistic style. After his death, the cult of the Aten was quickly abandoned, and the subsequent pharaohs Tutankhamun, Ay, and Horemheb erased all mention of Akhenaten's heresy, now known as the Amarna Period.
Around 1279 BC, Ramesses II, also known as Ramesses the Great, ascended the throne, and went on to build more temples, erect more statues and obelisks, and sire more children than any other pharaoh in history. A bold military leader, Ramesses II led his army against the Hittites in the Battle of Kadesh and, after fighting to a stalemate, finally agreed to the first recorded peace treaty around 1258 BC.[49] Egypt's wealth, however, made it a tempting target for invasion, particularly by the Libyans and the Sea Peoples. Initially, the military was able to repel these invasions, but Egypt eventually lost control of Syria and Palestine. The impact of external threats was exacerbated by internal problems such as corruption, tomb robbery and civil unrest. The high priests at the temple of Amun in Thebes accumulated vast tracts of land and wealth, and their growing power splintered the country during the Third Intermediate Period

Tunisia is the northernmost country in Africa. It is bordered by Algeria to the west, Libya to the southeast, and Mediterranean Sea to the north and east. Its size is almost 165,000 km² with an estimated population of just over 10.3 million. Its name is derived from the capital Tunis located in the north-east.
Tunisia is the smallest of the nations situated along the Atlas mountain range. The south of the country is composed of the Sahara desert, with much of the remainder consisting of particularly fertile soil and 1,300 km of coastline. Both played a prominent role in ancient times, first with the famous Phoenician city of Carthage, then as the Africa Province which was known as the "bread basket" of the Roman Empire. Later, Tunisia was occupied by Vandals during the 5th century AD, Byzantines in the 6th century, and Arabs in the 8th century. Under the Ottoman Empire, Tunisia was known as "Regency of Tunis". It passed under French protectorate in 1881. After obtaining independence in 1956, the country took the official name of the "Kingdom of Tunisia" at the end of the reign of Lamine Bey and the Husainid Dynasty. With the proclamation of the Tunisian republic in July 25, 1957, the nationalist leader Habib Bourguiba became its first president and led the modernization of the country.
Today Tunisia is an export-oriented country, in the process of liberalizing its economy [6] while, politically it is a dictatorship in all but name. Tunisia has an authoritarian regime in the guise of a procedural democracy led by Zine El Abidine Ben Ali who has governed as President since 1987 and has systematically diminished freedom of press and political pluralism while keeping appearances of democracy.
Tunisia has close relations with both the European Union — with whom it has an association agreement — and the Arab world. Tunisia is also a member of the Arab League and the African union. The regime's claimed success in oppressing political Islam and its pro-western foreign policy, has protected it from criticism for its lack of democratic accountability and its violations of human rights and freedom of press. France, the former colonial power, lends support to the regime in exchange for economic and political subservience.
Every year numerous Tunisians attempt illegal immigration to European countries like Italy by sea. Many die trying when the small boats in which they are riding capsize or go adrift at sea. Others reach their destination but are forcibly repatriated.
At the beginning of known recorded history, Tunisia was inhabited by Berber tribes. Its coast was settled by Phoenicians starting as early as the 10th century B.C. The city of Carthage was founded in the 9th century B.C. by settlers from Tyre, now in modern day Lebanon. Legend says, that Dido founded the city in 814 B.C., as retold in by the Greek writer Timaeus of Tauromenium. The settlers of Carthage brought their culture and religion from the Phoenicians and other Canaanites.

After a series of wars with Greek city-states of Sicily in the 5th century BC, Carthage rose to power and eventually became the dominant civilization in the Western Mediterranean. The people of Carthage worshipped a pantheon of Middle Eastern gods including Baal and Tanit. Tanit's symbol, a simple female figure with extended arms and long dress, is a popular icon found in ancient sites. The founders of Carthage also established a Tophet which was altered in Roman times.
The history of human culture in Tunisia goes back thousands of years. Early farming methods reached the Nile Valley from the Fertile Crescents region in about 5000 B.C from there, farming spread to the Maghreb by about 4000 B.C The humid coastal plains of central Tunisia were home to the early agricultural communities, populated by the ancestors of the Berber tribes.
Around the end of the 7th century and the beginning of 8th century the region was conquered by Arab Muslims, who founded the city of Kairouan which became the first city of Islam in North Africa ; in this period was erected the Great Mosque of Kairouan considered as the oldest and most prestigious sanctuary in the western Islamic world as well as a great masterpiece of Islamic art and architecture. Tunisia flourished under Arab rule. Extensive irrigation installations were constructed to supply towns with water and promote agriculture (especially olive production). This prosperity permitted luxurious court life and was marked by the construction of new Palace cities such as al-Abassiya (809) and Raqadda (877).
Successive Muslim dynasties ruled Tunisia with occasional instabilities caused mainly by Berber rebellions;[citation needed] of these reigns we can cite the Aghlabids (800-900) and Fatimids (909-972). After conquering Cairo, Fatimids abandoned North Africa to the local Zirids and Hammadid.[24] North Africa was submerged by their quarrels; political instability was connected to the decline of Tunisian trade and agriculture. In addition the invasion of Tunisia by Banu Hilal, a warlike Arab Bedouin tribes encouraged by Fatimids of Egypt to seize North Africa, sent the region's urban and economic life into further decline. The Arab historian Ibn Khaldun wrote that the lands ravaged by Banu Hilal invaders had become completely arid desert.
The coasts were held briefly by the Normans of Sicily in the 12th century and the following Arab reconquest made the last Christians in Tunisia disappear. In 1159, Tunisia was conquered by the Almohad caliphs. They were succeeded by the Berber Hafsids (c.1230–1574), under whom Tunisia prospered. In the late 16th century the coast became a pirate stronghold .

Tunisia is a country situated on the Mediterranean coast of North Africa, midway between the Atlantic Ocean and the Nile Valley. It is bordered by Algeria in the west and Libya in the south-east. An abrupt southern turn of its shoreline gives Tunisia two faces on the Mediterranean.
Despite its relatively small size, Tunisia has great geographical and climatic diversity. The Dorsal, an extension of the Atlas Mountains, traverses Tunisia in a northeasterly direction from the Algerian border in the west to the Cape Bon peninsula. North of the Dorsal is the Tell, a region characterized by low, rolling hills and plains, although in the northwestern corner of Tunisia, the land reaches elevations of 1,050 meters.
The Sahil is a plain along Tunisia's eastern Mediterranean coast famous because of its olive monoculture. Inland from the Sahil, between the Dorsal and a range of hills south of Gafsa, are the Steppes. Much of the southern region is semi-arid and desert.
Tunisia has a coastline 1,148 kilometres in length. In maritime terms, the country claims a contiguous zone of 24 nautical miles , and a territorial sea of 12 nmi.
Tunisia's climate is temperate in the north, with mild rainy winters and hot, dry summers. The south of the country is desert. The terrain in the north is mountainous, which, moving south, gives way to a hot, dry central plain. The south is semiarid, and merges into the Sahara. A series of salt lakes, known as chotts or shatts, lie in an east-west line at the northern edge of the Sahara, extending from the Gulf of Gabes into Algeria. The lowest point is Shatt al Gharsah, at -17 m, and the highest is Jebel ech Chambi, at 1544 metres.

Libya officially the Great Socialist People's Libyan Arab Jamahiriya , is a country located in North Africa. Bordering the Mediterranean Sea to the north, Libya lies between Egypt to the east, Sudan to the southeast, Chad and Niger to the south, and Algeria and Tunisia to the west.
With an area of almost 1,800,000 square kilometres (694,984 sq mi), Libya is the fourth largest country in Africa by area, and the 17th largest in the world. The capital, Tripoli, is home to 1.7 million of Libya's 5.7 million people. The three traditional parts of the country are Tripolitania, Fezzan, and Cyrenaica. Libya has the highest HDI in Africa and the fourth highest GDP per capita in Africa as of 2009, behind Seychelles, Equatorial Guinea and Gabon. These are largely due to its large petroleum reserves and low population.
The flag of Libya consists of a green field with no other characteristics. It is the only national flag in the world with just one color and no design, insignia, or other details.

Libya extends over 1,759,540 square kilometres (679,362 sq mi), making it the 17th largest nation in the world by size. Libya is somewhat smaller than Indonesia, and roughly the size of the US state of Alaska. It is bound to the north by the Mediterranean Sea, the west by Tunisia and Algeria, the southwest by Niger, the south by Chad and Sudan and to the east by Egypt. At 1,770 kilometres (1,100 mi), Libya's coastline is the longest of any African country bordering the Mediterranean. The portion of the Mediterranean Sea north of Libya is often called the Libyan Sea. The climate is mostly dry and desertlike in nature. However, the northern regions enjoy a milder Mediterranean climate.
Natural hazards come in the form of hot, dry, dust-laden sirocco . This is a southern wind blowing from one to four days in spring and autumn. There are also dust storms and sandstorms. Oases can also be found scattered throughout Libya, the most important of which are Ghadames and Kufra.

The Libyan Desert, which covers much of Libya, is one of the most arid places on earth. In places, decades may pass without rain, and even in the highlands rainfall seldom happens, once every 5–10 years. At Uweinat, as of 2006 the last recorded rainfall was in September 1998. There is a large depression, the Qattara Depression, just to the south of the northernmost scarp, with Siwa oasis at its western extremity. The depression continues in a shallower form west, to the oases of Jaghbub and Jalo.
Likewise, the temperature in the Libyan desert can be extreme; in 1922, the town of Al 'Aziziyah, which is located Southwest of Tripoli, recorded an air temperature of 57.8 °C (136.0 °F), generally accepted as the highest recorded naturally occurring air temperature reached on Earth.
There are a few scattered uninhabited small oases, usually linked to the major depressions, where water can be found by digging to a few feet in depth. In the west there is a widely dispersed group of oases in unconnected shallow depressions, the Kufra group, consisting of Tazerbo, Rebianae and Kufra. Aside from the scarps, the general flatness is only interrupted by a series of plateaus and massifs near the centre of the Libyan Desert, around the convergence of the Egyptian-Sudanese-Libyan borders.
Slightly further to the south are the massifs of Arkenu, Uweinat and Kissu. These granite mountains are ancient, having formed long before the sandstones surrounding them. Arkenu and Western Uweinat are ring complexes very similar to those in the Aïr Mountains. Eastern Uweinat is a raised sandstone plateau adjacent to the granite part further west. The plain to the north of Uweinat is dotted with eroded volcanic features. With the discovery of oil in the 1950s also came the discovery of a massive aquifer underneath much of the country. The water in this aquifer pre-dates the last ice ages and the Sahara desert itself. The country is also home to the Arkenu craters, double impact craters found in the desert.

The Libyan economy depends primarily upon revenues from the oil sector, which constitute practically all export earnings and about one-quarter of gross domestic product . The World Bank defines Libya as an 'Upper Middle Income Economy', along with only seven other African countries. In the early 1980s, Libya was one of the wealthiest countries in the world; its GNP per capita was higher than that of countries such as Italy, Singapore, South Korea, Spain and New Zealand.
Today, high oil revenues and a small population give Libya one of the highest GDPs per person in Africa and have allowed the Libyan state to provide an extensive level of social security, particularly in the fields of housing and education. Many problems still beset Libya's economy however; unemployment is the highest in the region at 21% according to the latest census figures.
Compared to its neighbours, Libya enjoys a low level of both absolute and relative poverty. Libyan officials in the past six years have carried out economic reforms as part of a broader campaign to reintegrate the country into the global capitalist economy.This effort picked up steam after UN sanctions were lifted in September 2003, and as Libya announced in December 2003 that it would abandon programmes to build weapons of mass destruction.
Libya has begun some market-oriented reforms. Initial steps have included applying for membership of the World Trade Organization, reducing subsidies, and announcing plans for privatisation. Authorities have privatised more than 100 government owned companies since 2003 in industries including oil refining, tourism and real estate, of which 29 are 100% foreign owned.[81] The non-oil manufacturing and construction sectors, which account for about 20% of GDP, have expanded from processing mostly agricultural products to include the production of petrochemicals, iron, steel and aluminium.
Climatic conditions and poor soils severely limit agricultural output, and Libya imports about 75% of its food. Water is also a problem, with some 28% of the population not having access to safe drinking water in 2000.[82] The Great Manmade River project is tapping into vast underground aquifers of fresh water discovered during the quest for oil, and is intended to improve the country's agricultural output.
Under the previous Prime Minister, Shukri Ghanem, and current prime minister Baghdadi Mahmudi, Libya is undergoing a business boom. Many government-run industries are being privatised. Many international oil companies have returned to the country, including oil giants Shell and ExxonMobil.
Tourism is on the rise, bringing increased demand for hotel accommodation and for capacity at airports such as Tripoli International. A multi-million dollar renovation of Libyan airports has recently been approved by the government to help meet such demands.[84] At present 130,000 people visit the country annually; the Libyan government hopes to increase this figure to 10,000,000 tourists.Saif al-Islam al-Gaddafi, the oldest son of Muammar al-Gaddafi, is involved in a green development project called the Green Mountain Sustainable Development Area, which seeks to bring tourism to Cyrene and to preserve Greek ruins in the area.

Canary Islands

The Canary Islands are a Spanish archipelago which, in turn, forms one of the Spanish Autonomous Communities and an Outermost Region of the European Union. The archipelago is located just off the northwest coast of mainland Africa, 100 km west of the disputed border between Morocco and the Western Sahara. The sea currents which depart from Canary's coasts used to lead ships away to America. The islands from largest to smallest are: Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, El Hierro, Alegranza, La Graciosa and Montaña Clara.
Canary Islands has great natural attractions, climate and beaches make the islands a major tourist destination, being visited each year by about 12 million people (11,986,059 in 2007, noting 29% of Britons, 22% of Spanish not canaries and 21% of Germans). Among the islands, Tenerife is the most number of tourists received annually, followed by Gran Canaria and Lanzarote. The archipelago pincipal tourist attraction is the Teide National Park where the highest mountain in Spain and third largest volcano in the world , receives over 2.8 million visitors annually.
Canary Islands currently has a population of 2,098,593 inhabitants, making it the eighth most populous of Spain's autonomous communities, with a density of 281.8 inhabitants per km². Tenerife is its most populous island with approximately one million inhabitants; the island of Gran Canaria is the second most-populous. The total area of the archipelago is 7447 km². It also enjoys sub-tropical climate with longer hot days in summer and cool in winter.
The status of capital city is shared by the cities of Santa Cruz de Tenerife and Las Palmas de Gran Canaria, which in turn are the capitals of the provinces of Santa Cruz de Tenerife and Las Palmas. Until 1927 Santa Cruz de Tenerife was the only capital. The third largest city of the Canary Islands is San Cristóbal de La Laguna on the island of Tenerife.

Tenerife, with 865,070 inhabitants, is both the Canary Islands' and Spain's most populous island. Tenerife is also the largest island of the archipelago. The island of Fuerteventura is the second largest in the archipelago and located 100 km from the African coast.
The islands form the Macaronesia ecoregion with the Azores, Cape Verde, Madeira, and the Savage Isles. The archipelago consists of seven large and several smaller islands, all of which are volcanic in origin. The Teide volcano on Tenerife is the highest mountain in Spain, and the third largest volcano on Earth on a volcanic ocean island. All the islands except La Gomera have been active in the last million years; four of them have historical records of eruptions since European discovery. The islands rise from Jurassic oceanic crust associated with the opening of the Atlantic. Underwater magmatism commenced during the Cretaceous, and reached the ocean's surface during the Miocene. The islands are considered as a distinct physiographic section of the Atlas Mountains province, which in turn is part of the larger African Alpine System division.
According to the position of the islands with respect to the NE trade winds, the climate can be mild and wet or very dry. Several native species form laurisilva forests.
Four of Spain's thirteen national parks are located in the Canary Islands, more than any other autonomous community. In the early 90's, there were only five Spanish national parks, four of them being the Canarian parks, and the other one Doñana. The parks are:

Morocco is a country located in North Africa. It has a population of nearly 32 million and an area of 710.850 km².
Its capital is Rabat, and its largest city is Casablanca; other large cities includes Fes, Salé, Marrakesh, Tangier, Meknes, Oujda and Tetouan.
Morocco has a rich culture and civilization, which remained mainly indigenous throughout times and the Moroccan cuisine has long been considered as one of the most diversified cuisines in the world.
Morocco has a coast on the Atlantic Ocean that reaches past the Strait of Gibraltar into the Mediterranean Sea. It is bordered by Spain to the north , Algeria to the east, and Mauritania to the south.
The information technology and communications sectors have been witnessing significant expansion as well. Morocco is the first country in North Africa to install a 3G network. The number of Internet subscribers in the country jumped 73% in 2006 over the year-ago period. Further, a new offshore site at Casablanca, with state-of-the-art technologies and other incentives, has grabbed the attention of many global multinationals. Setting up offshore service centers in the nation has become tempting. Such is the rate of growth, that off-shoring and IT activities are estimated to contribute $500 million to the country’s GDP and employ 30,000 people by 2015. The communications sector already accounts for half of all foreign direct investments Morocco received over the past five years.
Morocco is the world's third-largest producer of phosphorus and the price fluctuations of phosphates on the international market greatly influence Morocco's economy
Berbers constitute the largest ethnic group in the country although arabization played a key role in the moroccan culture, which resulted in a majority of arabic speaking berber-ethnic population.

Because of the conflict over Western Sahara, the status of both regions of "Saguia el-Hamra" and "Río de Oro" is disputed. The United Nations views Western Sahara as a non-self-governing territory, and as a case of unfinished decolonization. Morocco's rule in the territory is not internationally recognized, nor is the independent republic proposed by Polisario, a Saharawi group which fought against the Spanish colonial rule and then for Western Sahara's independence as the Sahrawi Arab Democratic Republic . There is a ceasefire in effect since 1991, and a UN mission is tasked with organizing a referendum on whether the territory should become independent or recognized as a part of Morocco. At the time, both parties signed an agreement to this effect, but Morocco has since 2000 refused to accept such a referendum, while Polisario demands that it be held.
The territory is mostly administered as the Southern Provinces by Morocco since Spain handed over the territory to Morocco and Mauritania after the Madrid Accords in 1975-76. Part of the territory, the Free Zone, is controlled by the Polisario Front as the Sahrawi Arab Democratic Republic. A UN-administered cease-fire has been in effect since September, 1991.

The geography of Morocco spans from the Atlantic Ocean, to mountainous areas, to the Sahara . Morocco is a Northern African country, bordering the North Atlantic Ocean and the Mediterranean Sea, between Algeria and the annexed Western Sahara.
A large part of Morocco is mountainous. The Atlas Mountains are located mainly in the center and the south of the country. The Rif Mountains are located in the north of the country. Both ranges are mainly inhabited by the Berber people. At 172,402 sq mi , Morocco is the fifty-seventh largest country in the world . Algeria borders Morocco to the east and southeast though the border between the two countries has been closed since 1994.
There are also four Spanish enclaves on the Mediterranean coast: Ceuta, Melilla, Peñón de Vélez de la Gomera, Peñón de Alhucemas, and the Chafarinas islands, as well as the disputed islet Perejil. Off the Atlantic coast the Canary Islands belong to Spain, whereas Madeira to the north is Portuguese. To the north, Morocco is bordered by and controls part of the Strait of Gibraltar, giving it power over the waterways in and out of the Mediterranean sea.
The Rif mountains occupy the region bordering the Mediterranean from the north-west to the north-east. The Atlas Mountains run down the backbone of the country, from the south west to the north east. Most of the south east portion of the country is in the Sahara Desert and as such is generally sparsely populated and unproductive economically. Most of the population lives to the north of these mountains, while to the south is the desert. To the south, lies the Western Sahara, a former Spanish colony that was annexed by Morocco in 1975. Morocco claims that the Western Sahara is part of its territory and refers to that as its Southern Provinces.
Morocco's capital city is Rabat; its largest city is its main port, Casablanca. Other cities include Agadir, Essaouira, Fes, Marrakech, Meknes, Mohammadia, Oujda, Ouarzazat, Safi, Salé, Tangier and Tétouan.
Morocco is represented in the ISO 3166-1 alpha-2 geographical encoding standard by the symbol MA. This code was used as the basis for Morocco's internet domain, .ma.
The climate is Mediterranean in the North and in some mountains , which becomes more extreme towards the interior regions. The terrain is such that the coastal plains are rich and accordingly, they comprise the backbone for agriculture, especially in the North. Forests cover about 12% of the land while arable land accounts for 18%. 5% is irrigated. In the Atlas ( Middle Atlas), there's some different climates: Mediterranean , Maritime Temperate that allow different species of oaks, moss carpets, junipers, atlantic cedars and many other plants, to form extensive and very rich humid cloud forests. In the highest peaks a different climate may occur. On the other side of Atlas mountains , the climate changes, due to the barrier/shelter effect of these mountainous system, turning it very dry and extremely warm during the summer , especially on the lowlands and on the valleys faced to the Sahara. Here it starts the big Desert Sahara and it's perfectly visible, for example, on the Draa Valley, on which it's possible to find oasis, sand dunes and rocky desert landscapes. So the climate in this region is desert.

Alexandria, with a population of 4.1 million, is the second-largest city in Egypt, and is the country's largest seaport, serving about 80% of Egypt's imports and exports. Alexandria is also an important tourist resort. Alexandria extends about 32 km (20 mi) along the coast of the Mediterranean Sea in north-central Egypt. It is home to the Bibliotheca Alexandrina , It is an important industrial centre because of its natural gas and oil pipelines from Suez, another city in Egypt.
In ancient times, Alexandria was one of the most famous cities in the world. It was founded around a small pharaonic town c. 331 BC by Alexander the Great. It remained Egypt's capital for nearly a thousand years, until the Muslim conquest of Egypt in AD 641 when a new capital was founded at Fustat. Alexandria was known because of its lighthouse (Pharos), one of the Seven Wonders of the Ancient World; its library ; and the Catacombs of Kom el Shoqafa, one of the Seven Wonders of the Middle Ages. Ongoing maritime archaeology in the harbour of Alexandria, which began in 1994, is revealing details of Alexandria both before the arrival of Alexander, when a city named Rhacotis existed there, and during the Ptolemaic dynasty.
From the late 19th century, it became a major centre of the international shipping industry and one the most important trading centres in the world, both because it profited from the easy overland connection between the Mediterranean Sea and the Red Sea, and the lucrative trade in Egyptian cotton.

Alexandria was founded by Alexander the Great in April 331 BC . Alexander's chief architect for the project was Dinocrates. Alexandria was intended to supersede Naucratis as a Hellenistic centre in Egypt, and to be the link between Greece and the rich Nile Valley. An Egyptian city, Rhakotis, already existed on the shore, and later gave its name to Alexandria in the Egyptian language . It continued to exist as the Egyptian quarter of the city. A few months after the foundation, Alexander left Egypt for the East and never returned to his city. After Alexander departed, his viceroy, Cleomenes, continued the expansion. Following a struggle with the other successors of Alexander, his general Ptolemy succeeded in bringing Alexander's body to Alexandria.
Although Cleomenes was mainly in charge of seeing to Alexandria's continuous development, the Heptastadion and the mainland quarters seem to have been primarily Ptolemaic work. Inheriting the trade of ruined Tyre and becoming the centre of the new commerce between Europe and the Arabian and Indian East, the city grew in less than a generation to be larger than Carthage. In a century, Alexandria had become the largest city in the world and for some centuries more, was second only to Rome. It became the main Greek city of Egypt, with an extraordinary mix of Greeks from many cities and backgrounds.
Alexandria was not only a centre of Hellenism but was also home to the largest Jewish community in the world. The Septuagint, a Greek translation of the Hebrew Bible, was produced there. The early Ptolemies kept it in order and fostered the development of its museum into the leading Hellenistic centre of learning but were careful to maintain the distinction of its population's three largest ethnicities: Greek, Jewish, and Egyptian. From this division arose much of the later turbulence, which began to manifest itself under Ptolemy Philopater who reigned from 221–204 BC. The reign of Ptolemy VIII Physcon from 144–116 BC was marked by purges and civil warfare.
The city passed formally under Roman jurisdiction in 80 BC, according to the will of Ptolemy Alexander but only after it had been under Roman influence for more than a hundred years. It was captured by Julius Caesar in 47 BC during a Roman intervention in the domestic civil war between king Ptolemy XIII and his advisors, and usurper queen Cleopatra VII. It was finally captured by Octavian, future emperor Augustus on 1 August 30 BC, with the name of the month later being changed to august to commemorate his victory.
In AD 115, vast parts of Alexandria were destroyed during the Greek-Jewish civil wars, which gave Hadrian and his architect, Decriannus, an opportunity to rebuild it. In 215 the emperor Caracalla visited the city and, because of some insulting satires that the inhabitants had directed at him, abruptly commanded his troops to put to death all youths capable of bearing arms. On 21 July 365, Alexandria was devastated by a tsunami (365 Crete earthquake), an event two hundred years later still annually commemorated as "day of horror".[4] In the late 4th century, persecution of pagans by newly Christian Romans had reached new levels of intensity. In 391, the Patriarch Theophilus destroyed all pagan temples in Alexandria under orders from Emperor Theodosius I. The Brucheum and Jewish quarters were desolate in the 5th century. On the mainland, life seemed to have centered in the vicinity of the Serapeum and Caesareum, both which became Christian churches. The Pharos and Heptastadium quarters, however, remained populous and were left intact.

In 619, Alexandria fell to the Sassanid Persians. Although the Byzantine Emperor Heraclius recovered it in 629, in 641 the Arabs under the general Amr ibn al-As captured it after a siege that lasted fourteen months.
Alexandria figured prominently in the military operations of Napoleon's expedition to Egypt in 1798. French troops stormed the city on 2 July 1798, and it remained in their hands until the arrival of a British expedition in 1801. The British won a considerable victory over the French at the Battle of Alexandria on 21 March 1801, following which they besieged the city, which fell to them on 2 September 1801. Mohammed Ali, the Ottoman Governor of Egypt, began rebuilding the city around 1810, and by 1850, Alexandria had returned to something akin to its former glory. In July 1882, the city came under bombardment from British naval forces and was occupied. In July 1954, the city was a target of an Israeli bombing campaign that later became known as the Lavon Affair. Only a few months later, Alexandria's Mansheyya Square was the site of a failed assassination attempt on Gamal Abdel Nasser.

Persistent efforts have been made to explore the antiquities of Alexandria. Encouragement and help have been given by the local Archaeological Society, and by many individuals, notably Greeks proud of a city which is one of the glories of their national history.
The past and present directors of the museum have been enabled from time to time to carry out systematic excavations whenever opportunity is offered; D. G. Hogarth made tentative researches on behalf of the Egypt Exploration Fund and the Society for the Promotion of Hellenic Studies in 1895; and a German expedition worked for two years (1898–1899). But two difficulties face the would-be excavator in Alexandria: lack of space for excavation and the underwater location of some areas of interest.
Since the great and growing modern city stands immediately over the ancient one, it is almost impossible to find any considerable space in which to dig, except at enormous cost. Also, the general subsidence of the coast has submerged the lower-lying parts of the ancient town under water. This underwater section, containing many of the most interesting sections of the Hellenistic city, including the palace quarter, is still being extensively investigated by the French underwater archaeologist Franck Goddio and his team. It raised a noted head of Caesarion. These are being opened up to tourists, to some controversy. The spaces that are most open are the low grounds to northeast and southwest, where it is practically impossible to get below the Roman strata.
The most important results were those achieved by Dr. G. Botti, late director of the museum, in the neighbourhood of “Pompey's Pillar”, where there is a good deal of open ground. Here substructures of a large building or group of buildings have been exposed, which are perhaps part of the Serapeum. Nearby, immense catacombs and columbaria have been opened which may have been appendages of the temple. These contain one very remarkable vault with curious painted reliefs, now artificially lit and open to visitors.
The objects found in these researches are in the museum, the most notable being a great basalt bull, probably once an object of cult in the Serapeum. Other catacombs and tombs have been opened in Kom al-Shoqqafa and Ras al-Tiin .
The German excavation team found remains of a Ptolemaic colonnade and streets in the north-east of the city, but little else. Hogarth explored part of an immense brick structure under the mound of Kom al-Dikka, which may have been part of the Paneum, the Mausolea, or a Roman fortress.
The making of the new foreshore led to the dredging up of remains of the Patriarchal Church; and the foundations of modern buildings are seldom laid without some objects of antiquity being discovered. The wealth underground is doubtlessly immense; but despite all efforts, there is not much for antiquarians to see in Alexandria outside the museum and the neighbourhood of “Pompey's Pillar”. The native tomb-robbers, well-sinkers, dredgers, and the like, however, come upon valuable objects from time to time, most of which find their way into private collections.

The Nile

The Nile is a major north-flowing river in Africa, generally regarded as the longest river in the world.
The Nile has two major tributaries, the White Nile and Blue Nile, the latter being the source of most of the Nile's water and fertile soil, but the former being the longer of the two. The White Nile rises in the Great Lakes region of central Africa, with the most distant source in southern Rwanda at 2°16′55.92″S 29°19′52.32″E, and flows north from there through Tanzania, Lake Victoria, Uganda and southern Sudan, while the Blue Nile starts at Lake Tana in Ethiopia at 12°2′8.8″N 37°15′53.11″E, flowing into Sudan from the southeast. The two rivers meet near the Sudanese capital of Khartoum.
The northern section of the river flows almost entirely through desert, from Sudan into Egypt, a country whose civilization has depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along the banks of the river. The Nile ends in a large delta that empties into the Mediterranean Sea.

The source of the Nile is sometimes considered to be Lake Victoria, but the lake itself has feeder rivers of considerable size. The most distant stream—and thus the ultimate source of the Nile—emerges from Nyungwe Forest in Rwanda, via the Rukarara, Mwogo, Nyabarongo and Kagera rivers, before flowing into Lake Victoria in Tanzania near the town of Bukoba.
The Nile leaves Lake Victoria at Ripon Falls near Jinja, Uganda, as the Victoria Nile. It flows for approximately 500 kilometres (300 mi) farther, through Lake Kyoga, until it reaches Lake Albert. After leaving Lake Albert, the river is known as the Albert Nile. It then flows into Sudan, where it is known as the Bahr al Jabal . The Bahr al Ghazal, itself 716 kilometres (445 mi) long, joins the Bahr al Jabal at a small lagoon called Lake No, after which the Nile becomes known as the Bahr al Abyad, or the White Nile, from the whitish clay suspended in its waters. When the Nile flooded it left a rich silty deposit which fertilised the soil. The Nile no longer floods annually since the completion of the Aswan Dam in 1970. From Lake No, the river flows to Khartoum. An anabranch river, the Bahr el Zeraf, flows out of the Nile's Bahr al Jabal section and rejoins the White Nile.
The term "White Nile" is used in both a general sense, referring to the entire river above Khartoum, and in a limited sense, describing the section between Lake No and Khartoum.
The flow rate of the Albert Nile at Mongalla is almost constant throughout the year and averages 1,048 m3/s (37,000 cu ft/s). After Mongalla, the Nile is known as the Bahr El Jebel, which enters the enormous swamps of the Sudd region of Sudan. More than half of the Nile's water is lost in this swamp to evaporation and transpiration. The average flow rate in the Bahr El Jebel at the tails of the swamps is about 510 m3/s (18,000 cu ft/s). From here it soon meets with the Sobat River and forms the White Nile.
The Bahr al Ghazal and the Sobat River are the two most important tributaries of the White Nile in terms of drainage area and discharge. The Bahr al Ghazal's drainage basin is the largest of any of the Nile's sub-basins, measuring 520,000 square kilometres (200,000 sq mi) in size, but it contributes a relatively small amount of water, about 2 m3/s (71 cu ft/s) annually, due to tremendous volumes of water being lost in the Sudd wetlands. The Sobat River, which joins the Nile a short distance below Lake No, drains about half as much land, 225,000 km2 (86,900 sq mi), but contributes 412 cubic metres per second (14,500 cu ft/s) annually to the Nile.[4] When in flood the Sobat carries a large amount of sediment, adding greatly to the White Nile's color.
The average flow of the White Nile at Malakal, just below the Sobat River, is 924 m3/s (32,600 cu ft/s); the peak flow is approximately 1,218 m3/s (43,000 cu ft/s) in early March and minimum flow is about 609 m3/s (21,500 cu ft/s) in late August. This fluctuation is due the substantial variation in the flow of the Sobat, which has a minimum flow of about 99 m3/s (3,500 cu ft/s) in August and a peak flow of over 680 m3/s (24,000 cu ft/s) in early March. During the dry season (January to June) the White Nile contributes between 70% and 90% of the total discharge from the Nile.
The Blue Nile to Ethiopians springs from Lake Tana in the Ethiopian Highlands. The Blue Nile flows about 1,400 kilometres (870 mi) to Khartoum, where the Blue Nile and White Nile join to form the Nile. 90% of the water and 96% of the transported sediment carried by the Nile originates in Ethiopia, with 59% of the water from the Blue Nile (the rest being from the Tekezé, Atbarah, Sobat, and small tributaries). The erosion and transportation of silt only occurs during the Ethiopian rainy season in the summer, however, when rainfall is especially high on the Ethiopian Plateau; the rest of the year, the great rivers draining Ethiopia into the Nile (Sobat, Blue Nile, Tekezé, and Atbarah) have a weaker flow.
The Blue Nile contributes approximately 80-90% of the Nile River discharge. The flow of the Blue Nile varies considerably over its yearly cycle and is the main contribution to the large natural variation of the Nile flow. During the wet season the peak flow of the Blue Nile will often exceed 5,663 m3/s (200,000 cu ft/s) in late August. During the dry season the natural discharge of the Blue Nile can be as low as 113 m3/s (4,000 cu ft/s), although upstream dams regulate the flow of the river.
Before the placement of dams on the river the yearly discharge varied by a factor of 15 at Aswan. Peak flows of over 8,212 m3/s (290,000 cu ft/s) would occur during late August and early September and minimum flows of about 552 m3/s (19,500 cu ft/s) would occur during late April and early May.

Teneriffe Island

Tenerife, a Spanish island, is the largest of the seven Canary Islands in the Atlantic Ocean off the coast of Africa. Tenerife has an area of 2034.38 square kilometers, and 899,833 inhabitants. It is the most populated island of the Canary Islands and Spain. About 43% of the population of the Canary Islands housing on this island, this is almost half the total population of the archipelago. About five million tourists visit Tenerife each year, which is also one of the busiest Spain resorts and the first of Canary Islands. Tenerife also has one of the world's largest carnivals, and the Carnival of Santa Cruz de Tenerife now aspires to become a World Heritage Site. The island's capital contains the architectural symbol of the Canary Islands, the modern Auditorio de Tenerife. Tenerife is the only Spanish island that has two airports and two ports .
Santa Cruz de Tenerife is the capital of the island and the seat of the island council . The city is capital of the autonomous community of Canary Islands , sharing governmental institutions such as Presidency and ministries. Between the 1833 territorial division of Spain and 1927 Santa Cruz de Tenerife was the sole capital of the Canary Islands, until in 1927 a decree ordered that the capital of the Canary Islands be shared, as it remains as at present.
The island is home to the University of San Fernando de La Laguna, which was founded in 1792. The University of La Laguna is the oldest university in the Canaries. San Cristóbal de La Laguna is the second city of the island and the third one of the archipelago. The city of La Laguna was also capital of the Canary Islands until Santa Cruz replaced it in 1833.
Tenerife also has the highest elevation of Spain, a World Heritage Site that is the third largest volcano in the world from its base, El Teide.
Tenerife is a rugged and volcanic island sculpted by successive eruptions throughout its history. There are four historically recorded volcanic eruptions, none of which has led to casualties. The first occurred in 1704, when the Arafo, Fasnia and Siete Fuentes volcanoes erupted simultaneously. Two years later, in 1706, the greatest eruption occurred at Trevejo. This volcano produced great quantities of lava which buried the city and port of Garachico. The last eruption of the 18th century happened in 1798 at Cañadas de Teide, in Chahorra. Finally, and most recently, in 1909 the Chinyero volcano, in the municipality of Santiago del Teide, erupted.
The island is located between 28º and 29º N and the 16º and 17º meridian. It is situated north of the Tropic of Cancer, occupying a central position between the other Canary Islands of Gran Canaria, La Gomera and La Palma. The island is about 300 km (186 mi) from the African coast, and approximately 1,000 km from the Iberian Peninsula. Tenerife is the largest island of the Canary Islands archipelago, with a surface area of 2,034.38 km2 and the longest coastline amounting to 342 km.
In addition, the highest point, Mount Teide, with an elevation of 3,718 m above sea level is the highest point in all of Spain. It comprises about 200 small barren islets or large rocks including Roques de Anaga, Roque de Garachico, and Fasnia adding a further 213,835 m2 to the total area.
Tenerife is known internationally as the "Island of Eternal Spring" (Isla de la Eterna Primavera).[36] The island, being on a latitude of the Sahara Desert, enjoys a warm climate year-round with an average of 20° - 22°C in the winter and 26° - 28°C in the summer and high sunshine totals. The moderate climate of Tenerife is controlled to a great extent by the tradewinds, whose humidity, principally, is condensed over the north and northeast of the island, creating cloud banks that range between 600 and 1,800 meters in height. The cold sea currents of the Canary Islands, also have a cooling effect on the coasts and its beaches and the topography of the landscape plays a role in climatic differences on the island with its many valleys.

The average temperatures, however, can fluctuate between 17-18°C and 24-25°C in the winter season. Evidently there are climatic contrasts which do occur on the island, particularly during the winter months when it is possible to enjoy the warm sunshine on the coast and experience snow within just miles, 3000 metres above sea level on Teide. There is also a contrast in climate between different parts of the island at a lower altitude, even in proximity, notably between the cities of Santa Cruz de Tenerife and San Cristóbal de La Laguna. Santa Cruz generally experiences a warm climate throughout the year with temperatures noticeably greater than at the bordering La Laguna, where frequently it is colder with a greater chance of rainfall.
The north and the south of Tenerife similarly have different climatic characteristics. The windward side of the island receives 73% of all precipitation on the island, and the relative humidity of the air is superior and the insolation inferior. The pluviometric maximums are registered on the windward side at an average altitude of between 1.000-1.200 ms, almost exclusively in the La Orotava mountain range. However, although climatic differences in rainfall and sunshine on the island exist, overall annual precipitation is very low with some of the summer months often not receiving any days of rainfall. In June and July in particular it is rare to receive any. The wettest season is during the winter, but in December, for instance, an average of five days of rainfall can be expected, and even this is partly attributed to snowfall on Teide.

Isle de Teneriffe


The Republic of Guinea-Bissau is located in West Africa. It is bordered by Senegal to the north, and Guinea to the south and east, with the Atlantic Ocean to its west.
It covers nearly 37,000 square kilometres with an estimated population of 1,600,000. Formerly the Portuguese colony of Portuguese Guinea, upon independence, the name of its capital, Bissau, was added to the country's name to prevent confusion with the Republic of Guinea. The country's per-capita gross domestic product is one of the lowest in the world.
Guinea-Bissau was once part of the kingdom of Gabu, part of the Mali Empire; parts of this kingdom persisted until the eighteenth century, while others were part of the Portuguese Empire. Portuguese Guinea was known also, from its main economic activity, as the Slave Coast.
Early reports of Europeans reaching this area include those of the Venetian Alvise Cadamosto's voyage of 1455, the 1479-1480 voyage by Flemish-French trader Eustache de la Fosse, and Diogo Cão who in the 1480s reached the Congo River and the lands of Bakongo, setting up thus the foundations of modern Angola, some 1200 km down the African coast from Guinea-Bissau.
Although the rivers and coast of this area were among the first places colonized by the Portuguese, since the 16th century, the interior was not explored until the nineteenth century. The local African rulers in Guinea, some of whom prospered greatly from the slave trade, had no interest in allowing the Europeans any further inland than the fortified coastal settlements where the trading took place. African communities that fought back against slave traders had even greater incentives to distrust European adventurers and would-be settlers. The Portuguese presence in Guinea was therefore largely limited to the port of Bissau and Cacheu, although isolated European farmer-settlers established farms along Bissau's inland rivers.
For a brief period in the 1790s the British attempted to establish a rival foothold on an offshore island, at Bolama. But by the 19th century the Portuguese were sufficiently secure in Bissau to regard the neighbouring coastline as their own special territory, also up north in part of present South Senegal.
An armed rebellion beginning in 1956 by the African Party for the Independence of Guinea and Cape Verde under the leadership of Amílcar Cabral gradually consolidated its hold on then Portuguese Guinea. Unlike guerrilla movements in other Portuguese colonies, the PAIGC rapidly extended its military control over large portions of the territory, aided by the jungle-like terrain, its easily reached borderlines with neighbouring allies and large quantities of arms from Cuba, China, the Soviet Union, and left-leaning African countries.
Cuba also agreed to supply artillery experts, doctors and technicians. The PAIGC even managed to acquire a significant anti-aircraft capability in order to defend itself against aerial attack. By 1973, the PAIGC was in control of many parts of Guinea. Independence was unilaterally declared on September 24, 1973. Recognition became universal following the April 25, 1974 socialist-inspired military coup in Portugal which overthrew Lisbon's Estado Novo regime.
Luís Cabral was appointed the first President of Guinea-Bissau. Following independence local black soldiers that fought along with the Portuguese Army against the PAIGC guerrillas were slaughtered by the thousands. Some managed to escape and settled in Portugal or other African nations, one of the massacres occurred in the town of Bissorã. In 1980 the PAIGC admitted in its newspaper "Nó Pintcha" that many were executed and buried in unmarked collective graves in the woods of Cumerá, Portogole and Mansabá.
The country was controlled by a revolutionary council until 1984. The first multi-party elections were held in 1994, but an army uprising in 1998 led to the president's ousting and the Guinea-Bissau Civil War. Elections were held again in 2000 and Kumba Ialá was elected president.
In September 2003, a coup took place in which the military arrested Ialá on the charge of being "unable to solve the problems." After being delayed several times, legislative elections were held in March 2004 . A mutiny of military factions in October 2004 resulted in the death of the head of the armed forces, and caused widespread unrest.

Senegal Guinea Bissau

Cours de la Riviere de Senaga ou Senegal


Senegal is a country south of the Sénégal River in western Africa.It owes its name to the river that borders it to the East and North and that originates from the Fouta Djallon in Guinea. Senegal is externally bounded by the Atlantic Ocean to the west, Mauritania to the north, Mali to the east, and Guinea and Guinea-Bissau to the south; internally it almost completely surrounds The Gambia, namely on the north, east and south, exempting Gambia's short Atlantic Ocean coastline. Senegal covers a land area of almost 197,000 km², and has an estimated population of about 13.7 million.The climate is tropical with two seasons: the dry season and the rainy season.
Dakar the capital city of Senegal,is located to the westernmost tip of the country, about 300 miles away the Cape Verde Island, off the Atlantic Ocean. During colonial times, numerous trading Counters, belonging to various colonial empires were established along the coast. The town of St Louis became the capital of French Western Africa before it was moved to Dakar in 1902. Dakar later became its capital in 1960 at the time of independence from France.
Senegal is located on the west of the African continent. The Senegalese landscape consists mainly of the rolling sandy plains of the western Sahel which rise to foothills in the southeast. Here is also found Senegal's highest point, an otherwise unnamed feature near Nepen Diakha at 584 m (1,916 ft). The northern border is formed by the Senegal River, other rivers include the Gambia and Casamance Rivers. The capital Dakar lies on the Cap-Vert peninsula, the westernmost point of continental Africa.
The local climate is tropical with well-defined dry and humid seasons that result from northeast winter winds and southwest summer winds. Dakar's annual rainfall of about 600 mm (23.6 in) occurs between June and October when maximum temperatures average 27 °C (80.6 °F); December to February minimum temperatures are about 17 °C (62.6 °F). Interior temperatures can be substantially higher than along the coast, and rainfall increases substantially farther south, exceeding 1,500 mm (59.1 in) annually in some areas. The far interior of the country, in the region of Tambacounda, particularly on the border of Mali, temperatures can reach as high as 54 °C (129.2 °F).
The Cape Verde islands lie some 560 kilometers (348 mi) off the Senegalese coast, but Cap Vert ("Cape Green") is a maritime placemark, set at the foot of "Les Mammelles" , a 105-metre (344 ft) cliff resting at one end of the Cap Vert peninsula onto which is settled Senegal's capital Dakar, and 1 kilometre (0.62 mi) south of the "Pointe des Almadies", the western-most point in Africa.
