Leaders and rulers in ancient Greece

Ancient Greece was made up of different states which were ruled in different ways. Some were ruled by groups of rich and powerful people. Sparta had two kings and a small group of wise old men known as elders. Athens was ruled by the people of athens, voted for by the people, which prevented anyone getting too much power.
None of the states allowed women, foreigners or slaves to take part in government. In the fourth century Alexander the Great became the ruler of all Greece.
