The Spartans were very well disciplined soldiers. They defeated the people who lived near them and those people had to farm the land for the Spartans. These "helots" had to give the Spartans part of the food they grew and so the Spartans did not have to work. Instead, they learned how to be better soldiers. There were not many Spartans but there were many helots. Spartan military strength controlled the helots. The Spartans had two hereditary kings who led them in war. At home they were also ruled by a group of old men called the Gerousia (the senate).
