Why do communities
The harvest has failed and, like many others, you have little to eat. There are animals in the temple, but they are protected by law. Your cousin decides to steal one of the pigs to feed his family. You believe that laws should not be broken and try to persuade him not to steal the pig. But he steals the pig and is caught.

• What should be the main purpose of laws: to promote good behavior or to punish bad behavior?
• Do all communities need a system of laws to guide them?
Hold a class debate on these questions. As you prepare for the debate, think about what you have leaned about the changes that take place as civilizations grow and become more complex. As you read about the growth of civilization in this chapter, consider why societies developed systems of laws.

Turkey, down through Syria and Iraq, and finally to the Persian Gulf. Over six thousand years ago, the waters of these rivers provided the lifeblood that allowed the formation of farming settlements. These grew into villages and then cities.
Geography of the Fertile Crescent
A desert climate dominates the landscape between the Persian Gulf and the Mediterranean Sea in Southwest Asia. Yet within this dry region lies an arc of land that provided some of the best farming in Southwest Asia. The region’s curved shape and the richness of its land led scholars to call it the Fertile Crescent. It includes the lands facing the Mediterranean Sea and a plain that became known as Mesopotamia (MEHS•uh•puh•TAY•mee•uh). The word in Greek means “land between the rivers.”
The rivers framing Mesopotamia are the Tigris (TY•grihs) and...
