The term 'Spartan Workers' refers to the HELOTS, a population of enslaved people in ancient Sparta. The HELOTS were primarily composed of conquered Messenians, who were forced to work for the Spartan state. They were not allowed to own land or weapons, and were subject to harsh punishments if they disobeyed orders. The HELOTS were essential to the functioning of the Spartan economy, providing labor for agriculture and other industries.
