Men
Out of everyone in Ancient Greece, citizens had the most rights, but even then, they were separated into three classes. At the top were the aristocrats, the most wealthy and powerful people. They were split into several factions or clans and would control the important political positions. There were also the second class citizens, who wouldn't be quite as rich or own as much land as the aristocrats, but they still weren't very poor either. Lastly, there was the middle class. They would employ in trade, manufacturing, and business. Sometimes, people could move in between the classes by becoming poorer or gaining wealth. In school, only children of citizens would be educated. They would learn how to read, write, and do math first. Then they would study literature and music, and do athletics. Only men would be allowed to become citizens. Citizens were the most respected people in Ancient Greece.
Women
The women of Ancient Greece didn't have nearly as many rights as men did. They weren't allowed to vote, own land, or inherit. Their purpose was to serve in a house and raise children. Young girls would be educated similarly to boys, but they would focus more on dancing and music. Their time in school was mostly to prepare them for serving in a house. Spartan women were treated better than the rest of Ancient Greece, but even then they wouldn't be equal to the men.
Slaves
At the very bottom of the social structure were the slaves. Many people thought it was normal and necessary to have slaves. It's estimated that 15-40% of the Ancient Greek population were slaves. They were usually procured through war or kidnapping. They worked in over 200 different jobs, like agriculture, workshops, mines, and transport. Sometimes, they would be able to pay for their freedom with money. The ones in the army could be granted freedom by the state. Slaves were the least respected people in Ancient Greece.
