Thirty Tyrants
Moreover, the Thirty Tyrants also appointed a council of 500 men to perform the judicial functions that once had belonged to every Athenian citizen. In their brief régime, the Spartan oligarchs killed about five percent of the Athenian population, confiscated much property, and exiled democrats from the city proper. The fact that Critias, leader of the Thirty Tyrants, had been a pupil of Socrates was held against him.
