Why did the Egyptians build Memphis?

The Egyptians built Memphis around 3100 BCE as a strategic capital to unify Upper and Lower Egypt. Its location at the apex of the Nile Delta facilitated trade and communication, making it an essential economic and political center. Additionally, Memphis served as a religious hub, housing the great temple of Ptah, the god of creation and craftsmanship, which further solidified its importance in ancient Egyptian culture.
