Forced Conscription at age ten for state-sponsored indoctrination.
Forced homosexual relationships for all the fighting men
Strict wealth re-distribution so that all Spartan had exactly equal wealth regardless of effort or merit
Enslavement of the productive classes
Secret police who moved among the Helots killing out of hand anyone
who was too clever, to handsome, too popular....
Sparta was a Marxist state and earned it spot on the dustheap of history
Pol Pot would have been right at home. Sparta existed to do one thing - Thermopylae after that it was a nightmare.
