Who is the person who is captured and enslaved by the Spartans?

The person often associated with being captured and enslaved by the Spartans is the character known as "the Helot" or "Helots," who were a subjugated population in ancient Sparta. Helots were primarily the enslaved descendants of the original inhabitants of Laconia and Messenia, forced to work the land and serve Spartan citizens. In popular culture, such as the movie "300," the character of DiliOS, a Spartan warrior, is portrayed, but the broader context involves the systemic enslavement of the Helots by the Spartan state.
