Ostracism
in ancient Athens, the banishment of certain citizens by order of the popular assembly.
Ostracism was instituted by Cleisthenes at the end of the sixth century B.C. as a measure against the restoration of tyranny. First used in 488–487 B.C., it later became an instrument of political warfare. Once a year the popular assembly decided whether a vote of ostracism should be held. If the majority voted in favor of ostracism, a day was set for the procedure. Everyone having the right to vote in the popular assembly would write on a potsherd the name of any person who, in his opinion, was dangerous to the people. Any individual against whom at least 6,000 votes were cast was obliged to leave Athens within ten days, usually for a period of ten years. (According to other sources, 6,000 was the quorum necessary for the assembly.) Banished individuals did not lose their property or their rights as citizens.
Ostracism was not often practiced. Among those who were ostracized were Aristides (483–482 B.C.), Themistocles (471 B.C.), and the philosopher Damon, the teacher of Pericles (443 B.C.). The last known case of ostracism was in 417 B.C., when the demagogue Hyperbolus was banished from Athens. Similar institutions for banishing citizens existed in Argos, Syracuse, and certain other Greek cities.
