The document discusses the differences between citizens and subjects in ancient Greece and Mesopotamia. In Mesopotamia and Egypt, people were subjects who had no rights and had to obey kings and priests without question. In Greece, citizens were free native-born men who owned land and had rights like voting, holding office, owning property, and defending themselves in court. However, women, slaves, foreigners, and landless men were not considered citizens and lacked these rights. The document instructs students to compare the rights and responsibilities of citizens in ancient Greece to those in the United States.
