Egypt

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
