The Gerousia (γερουσία) was a council of elders.
In Sparta this governmental body was a gerontocracy that was made up of 60-year-old Spartan males. It was created by the Spartan lawgiver Lycurgus in the seventh century BC, in his Great Rhetra ("Great Pronouncement"). According to Lycurgus' biographer Plutarch, the Gerousia was the first significant constitutional innovation instituted by Lycurgus.
