Ancient Egypt was an ancient civilization in eastern North Africa, concentrated along the lower reaches of the Nile River in what is now the modern nation of Egypt. The civilization began 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 periods, known as kingdoms, separated by periods of relative instability known as Intermediate Periods. After the end of the last kingdom, known as the New Kingdom, the civilization of ancient Egypt entered a period of slow, steady decline, during which Egypt was conquered by a succession of foreign powers. The rule of the pharaohs officially ended in 31 BC when the early Roman Empire conquered Egypt and made it a province.

The civilization of ancient Egypt thrived from its ability to adapt to the conditions of the Nile River Valley. 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 that defeated foreign enemies and asserted 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 through an elaborate system of religious beliefs.

The many achievements of the ancient Egyptians included a system of mathematics, quarrying, surveying and construction techniques that facilitated the building of monumental pyramids, temples, obelisks, faience and glass technology, a practical and effective system of medicine, new forms of literature, irrigation systems and agricultural production techniques, and the earliest known peace treaty. Egypt left a lasting legacy: art and architecture were copied and antiquities paraded around the world, and monumental ruins have inspired the imaginations of tourists 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.

History

main: History of Egypt

By the late Paleolithic period, the arid climate of Northern Africa became increasingly hot and dry, forcing the populations of the area to concentrate along the Nile valley, and since nomadic hunter-gatherers began living in the region during the Pleistocene some 1.8 million years ago, the Nile has been the lifeline of Egypt. The fertile floodplain of the Nile gave humans the opportunity to develop a settled agricultural economy and a more sophisticated, centralized society that became a cornerstone in the history of human civilization.
