In Sparta how were helots usually enslaved?

Helots in Sparta were primarily enslaved through conquest and subjugation. They were originally the indigenous population of Messenia, which the Spartans conquered in the 8th century BCE. Following their defeat, the Messenian people were reduced to a subservient status, providing agricultural labor and supporting the Spartan economy. This system allowed Spartans to focus on military training and governance while relying on the labor of the helots.
