Early Dynastic Period of Egypt
The Early Dynastic Period, also known as Archaic Period or the Thinite Period (from Thinis, the hometown of its rulers), is the era of ancient Egypt that immediately follows the unification of Upper and Lower Egypt in c. 3150 BC. It is generally taken to include the First Dynasty and the Second Dynasty, lasting from the end of the archaeological culture of Naqada III until c. 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the Egyptian capital moved from Thinis to Memphis, with the unified land being ruled by an Egyptian god-king.
