Military
Military was very important to the spartans. Military service was required if you don't want to be a slave or low class. Military service started on the day of birth. Where you were tested to see if you were strong enough. If not, you would be left for the wolves or became a slave. At the age of seven, you started military training. You would be put through pain and lack of food, and sleep. At the age of 20, you went through a test to become a citizen, or soldier. Once you did, you lived in a barracks. You were required to get married and produce children during your service. The state bought you an area of land that slaves tended to in order to pay for your continued military service. At the age of 30, you were able to go home to your family, but continued to train until age 60, where you retired your military service.
