Final answer:
The helots enabled Spartan men to become a warrior class by providing essential labor and allowing the Spartans to focus on military training and government service.
Step-by-step explanation:
Spartan society was a military hierarchy that relied on the helots, or enslaved population, to enable Spartan men to become a warrior class.
The Spartans maintained control over the helots through various methods such as declaring war on them annually and having a secret police force to monitor them. The helots provided essential labor, allowing the Spartans to devote themselves to military training and government service.
