The Sumerians' Government and Class Structure

There were four classes of people in Sumer.
The highest was to be the ruler, high priest or official.
The next was to be a lesser priest, a scribe, merchant or artist.
Peasant farmers were third class, but slaves were the lowest rank.

The Sumerians lived in city-states, governed by powerful war leaders that eventually became rulers.The ruler collected taxes and kept records. They led armies and organized ceremonies to please their gods.
The rulers, along with the high priest and leading officials, had the most responsibility of the city.
