The Spartan assembly comprised the male citizens. The council (Gerousia) of 30 elders conducted normal business and placed important matters before the assembly for decisions.
There were the two kings, the Gerousia ( or council of Elders), The Ephorate and the Ekklesia (or the apella, or the Assembly).
The council called an assembly and placed significant matters before them on which the voted for and against.
The Spartan governent was a fusion of monarchy (the kings), oligarchy (the Gerousia) and democracy (the assembly/Ecclesia).
The Spartan government was an assembly of the citizens, with a council (Gerousia) to bring significant matters before the assembly, implement its decisions and administer between meetings. A dual kingship led in military and religious matters.
The Spartans did not have military government. They had a council of elders (ephors) and a popular assembly, at which all Spartan citizens could attend and vote.
The Spartan Council of Elders (Gerousia or Senate) was 28 citizens over the age of 60 elected for life by the Assembly of the (male) citizens plus the two kings of Sparta. It controlledthe running of the city-state, and referred important matters to the Assembly of citizens, with a veto over decisions of the Assembly.
