During this period Susa was re-organized as a large city, may be even a center for the country and the communities living there, who are generally known as the Elamites.
Before the end of the millennium Susa had been founded and covered about 10 hectares, with over forty other surrounding sites averaging 1.2 hectares each, thus two distinct levels of settlements, a manual administrative complexity’.
As one of the oldest sites of ancient civilization, Susa began its political and administrative life first as a city state contemporary, then as an empire rivaling Sumer in Mesopotamian and subsequently as the capital of one of the oldest empire of antiquity, Elam, around 3000 BC.
Large temples were erected for the newly unified Elamite tribes and the heads of these temples acted as rulers, guides and leaders.
Elamite Empire was the first Persian experience in empire building and state tradition.
