What roles do slaves play in Sparta and Athens?

In Sparta, slaves, known as helots, primarily worked the land and performed agricultural labor, allowing Spartan citizens to focus on military training and governance. Helots were subjected to harsh treatment and could be used in warfare, often serving as light infantry. In Athens, slaves played various roles, including household servants, laborers, and skilled artisans, contributing significantly to the economy. While Athenian slaves had some legal rights, they were still considered property and lacked personal freedom.
