The Spartans spent so much time training for battle that they would have starved without slaves called helots. The helots worked on the Spartans' farms. They grew the food for the Spartan soldiers and their families. Sparta, was a prominent city-state in ancient Greece. Although every Spartan man had a farm, he spent a lot of his time preparing for war. He became a soldier when he was 20. However, a boy's training began much earlier, when he left his family home at the age of 7, and went to live in an army school. Discipline was tough. He was allowed only one tunic, and had to walk barefoot even in cold weather.Children ran around naked. Boys practised fighting and did athletics. Girls also did physical exercises.
