There social structure put people with better jobs and better social levels higher on the rank, people like priests, kings, nobles, and government officials, as to where slaves, and enimes were the lowest rank. The government told civilians what to do, and organized their lives, so they basically ruled civilization. Civilians also followed the kings orders, because they believed that god supported the kings. One job they had back then was called a scribe, a scribe would record all the laws, and contracts too.
Sumerians believed that if hey made art or grew crops, god would help them in the afterlife.
