Concurrent with these cultural advances, a process of unification of the societies and towns of the upper Nile River, or Upper Egypt, occurred. At the same time the societies of the Nile Delta, or Lower Egypt, also underwent a unification process. Warfare between Upper Egypt and Lower Egypt occurred often. During his reign in Upper Egypt, King Narmer defeated his enemies on the delta and united both of the kingdoms of Upper Egypt and Lower Egypt under his single rule, which endured throughout Dynastic Egypt.
