The creator of the Spartan system of rule was the legendary lawgiver Lycurgus. He is associated with the drastic reforms that were instituted in Sparta after the revolt of the helots in the second half of the 7th century BCE. In order to prevent another helot revolt, Lycurgus devised the highly militarized communal system that made Sparta unique among the city-states of Greece. All his reforms were directed towards the three Spartan virtues: equality (among citizens), military fitness, and austerity. It is also probable that Lycurgus delineated the powers of the two traditional organs of the Spartan government, the gerousia and the apella.
