The Nile River in Egypt

History

The Nile Valley has been a site of continuous human habitation since at least the Paleolithic era. Traces of these early peoples appear in the form of artifacts and rock carvings along the terraces of the Nile and in the desert oases. In the 10th millennium BC, a grain-grinding culture using the earliest type of sickle blades had been replaced by another culture of hunter-gatherers and fishers using stone tools. Climate changes and/or overgrazing around 8000 BC began to desiccate the pastoral lands of Egypt, eventually forming the Sahara. Early tribal peoples migrated to the Nile River where they developed a settled agricultural economy and more centralized society.

By about 6000 BC, organized agriculture and large building construction had appeared in the Nile Valley. During the Neolithic, several predynastic cultures developed independently in Upper and Lower Egypt. The Badarian culture and the successor Naqada series are generally regarded as precursors to Dynastic Egyptian civilization. The earliest known Lower Egyptian site, Merimda, predates the Badarian by about seven hundred years. Contemporaneous Lower Egyptian communities coexisted with their southern counterparts for more than two thousand years, remaining somewhat culturally separate, but maintaining frequent contact through trade. The earliest known evidence of Egyptian hieroglyphic inscriptions appear during the predynastic period on Naqada III pottery vessels, dated to about 3200 BC.

A unified kingdom was founded circa 3150 BC by King Menes, giving rise to a series of dynasties that ruled Egypt for the next three millennia. Egyptians subsequently referred to their unified country as tAwy, meaning ‘Two Lands’; and later km.t (Coptic: Kīmi), the ‘Black Land’, a reference to the fertile black soil deposited by the Nile river. Egyptian culture flourished during this long period and remained distinctively Egyptian in its religion, arts, language and customs. The first two ruling dynasties of a unified Egypt set the stage for the Old Kingdom period, c.2700−2200 BC., famous for its many pyramids, most notably the Third Dynasty pyramid of Djoser and the Fourth Dynasty Giza Pyramids.
