Nagada
Nagada, also known as Naqada, is the type site of the prehistoric Egyptian Amratian culture ("Naqada I"), Gerzeh culture ("Naqada II") and Naqada III ("Dynasty 0") predynastic cultures.
Naqada existed before and during the union of Upper Egypt and Lower Egypt, the Naqada III or "protodynastic" period. The process of unification apparently started from Nagada.
