Definition: Ancient Egypt was divided into nomes or districts administered by nomarchs or governors from the predynastic period. At first, the nomarchs were royal officials who moved from post to post and had no pretense to independence or local ties. The post of nomarch eventually became hereditary, however, and nomarchs passed their offices to their sons.
Lower Egypt generally had 20 nomes and Upper Egypt, 22.
Examples:
Nome is the Greek term for what the Egyptians called sepat.
