Different levels of Sparan society had different impacts on the political life within Sparta. The kings were the political figurehead, then you had the Geriousia who passed bills, prepared business, deliberated public policy; the ephors - delt with foreign policy
The assemblies - which were all spartan men who had passed the agoge - listened adn voted on bills (meant to be a democratic part of the political insitutions)
