Third Dynasty
The first king of the Old Kingdom was Djoser (sometime between 2691 and 2625 BC) of the third dynasty, who ordered the construction of a pyramid (the Step Pyramid) in Memphis' necropolis, Saqqara. An important person during the reign of Djoser was his vizier, Imhotep.
It was in this era that formerly independent ancient Egyptian states became known as nomes, under the rule of the pharaoh. The former rulers were forced to assume the role of governors or otherwise work in tax collection. Egyptians in this era worshiped their pharaoh as a god, believing that he ensured the annual flooding of the Nile that was necessary for their crops. Egyptian views on the nature of time during this period held that the universe worked in cycles, and the Pharaoh on earth worked to ensure the stability of those cycles. They also perceived themselves as a specially selected people.
