The Gerousia (γερουσία) was the council of elders in ancient Sparta. Sometimes called Spartan senate in the literature, it was made up of the two Spartan kings, plus 28 Spartiates over the age of sixty, known as gerontes. The Gerousia was a prestigious body, holding extensive judicial and legislative powers, which shaped Sparta's policies.
Ancient Greeks considered that the Gerousia was created by the mythical Spartan lawgiver Lycurgus in his Great Rhetra, the constitution of Sparta.
