Roman Kingdom
Romulus selected 100 of the best men to form the Senate as an advisory council to the king. He called them patres, and their descendants became the patricians. He also divided the general populace into thirty curiae, named after thirty of the Sabine women who had intervened to end the war between Romulus and Tatius. The curiae formed the voting units in the Roman assemblies: Comitia Curiata.
