Egypt has endured as a unified state for more than 5,000 years, and archeological evidence indicates that a developed Egyptian society has existed for much longer. Egyptians take pride in their "pharaonic heritage" and in their descent from what they consider mankind's earliest civilization. The Arabic word for Egypt is Misr, which originally connoted "civilization" or "metropolis." Archeological findings show that primitive tribes lived along the Nile long before the dynastic history of the pharaohs began. By 6000 B.C., organized agriculture had appeared.

In about 3100 B.C., Egypt was united under a ruler known as Mena, or Menes, who inaugurated the 30 pharaonic dynasties into which Egypt's ancient history is divided--the Old and the Middle Kingdoms and the New Empire. For the first time, the use and managements of vital resources of the Nile River came under one authority.
