30 Tyrants
After the Peloponnesian War - 30 Tyrants
When Athens surrendered at the end of the Peloponnesian War, democracy was replaced by the oligarchic rule of the Thirty Tyrants. From 404-403 B.C., during the start of the period known as the Spartan hegemony (404-371 B.C.), hundreds of Athenians were killed, thousands exiled, and the number of the citizens was severely reduced.
