The Sumerians were polytheistic meaning they believed in many gods. Each was thought to have power over a natural force or a human activity—flooding, for example, or basket weaving. The Sumerians tried hard to please their gods. They built a grand temple called a ziggurat (ZIH• guh• RAT) to the chief god. The word ziggurat means “mountain of god” or “hill of heaven.” With tiers like a giant square wedding cake, the ziggurat dominated the city. At the top was a shrine, or special place of worship that only priests and priestesses could enter. The priests and priestesses were powerful and controlled much of the land. They may even have ruled at one time.
Later, kings ran the government. They led armies and organized building projects. The first kings were probably war heroes. Their position became hereditary, which meant that after a king died, his son took over. What Was Life Like in Sumer? While Sumerian kings lived in large palaces, ordinary people lived in small mud-brick houses. Most people in Sumer farmed. Some, however, were artisans (AHR•tuh•zuhns), or skilled workers who made metal products, cloth, or pottery. Other people in Sumer worked as merchants or traders. They traveled to other cities and towns and traded tools, wheat, and barley for copper, tin, and timber—things that Sumer did not have. People in Sumer were divided into three social classes. Generally, a person had to stay in the social class into which he or she was born. Only rarely could someone move up. The upper class included kings, priests, warriors, and government officials. In the middle class were artisans, merchants, farmers, and fishers. These people made up the largest group. The lower class were enslaved people who worked on farms or in the temples. Enslaved people were forced to serve others. Slaveholders thought of them as property. Some slaves were prisoners of war. Others were criminals. Still others were enslaved because they had to pay off their debts. Debts are money or goods owed to others. In Sumer, women and men had separate roles. Men headed the households. They also could decide whom their children would marry. Only males could go to school. Women, however, did have some rights. They could buy and sell property and run businesses.
