what was the name for the powerful leaders elected by the plebeians
Plebeian Council The Concilium Plebis (English: Plebeian Council or Plebeian Assembly) was the principal assembly of the ancient Roman Republic. It functioned as a legislative assembly, through which the plebeians (commoners) could pass laws, elect magistrates, and try judicial cases. The Plebeian Council was originally organized on the basis of the Curia. Thus, it was originally a "Plebeian Curiate Assembly". The Plebeian Council usually met in the well of the comitium and could only be convoked by the Tribune of the Plebs. The assembly elected the Tribunes of the Plebs and the plebeian aediles, and only the plebeians were allowed to vote.
Athenian democracy Before the first attempt at democratic government, Athens was ruled by a series of archons or chief magistrates, and the Areopagus, made up of ex-archons. The members of these institutions were generally aristocrats, who ruled the polis for their own advantage. In 621 BC Draco codified a set of "notoriously harsh" laws that were "a clear expression of the power of the aristocracy over everybody else." This did not stop the aristocratic families feuding amongst themselves to obtain as much power as possible.[5]
