when did egypt began to develop into a kingdom
Ancient Egypt The Early Dynastic Period was approximately contemporary to the early Sumerian-Akkadian civilisation of Mesopotamia and of ancient Elam. The third-century BC Egyptian priest Manetho grouped the long line of pharaohs from Menes to his own time into 30 dynasties, a system still used today.[22] He chose to begin his official history with the king named "Meni" (or Menes in Greek) who was believed to have united the two kingdoms of Upper and Lower Egypt (around 3100Â BC).[23]
