Answer:
In the cities of Ancient Greece the Council, called Boule, was a restricted assembly of citizens in charge of the ordinary affairs of the city.
In Athens, Solon converted the Boule into a council of 400 members (100 per tribe). Cleisthenes extended the number of bouleutas to 500, a number that would be preserved later. These were chosen annually by lottery among citizens over thirty years and received a payment of five obols. They were the true governing body of democracy and enjoyed deliberative, administrative and judicial functions.
