How many people were slaves in Sparta?

In Sparta, the majority of the population were not citizens but rather a class of serfs known as helots. Estimates suggest that there were around 150,000 to 250,000 helots, significantly outnumbering the Spartan citizens, who numbered around 8,000 to 10,000. The helots were primarily responsible for agricultural labor, allowing Spartan citizens to focus on military training and governance. This system created a dynamic of control and fear, as helots could revolt against their Spartan overlords.
