The Thirty severely reduced the number of rights of Athenian citizens. Instead of all Athenians participating in legal functions, only a specially selected 500 could. Only 3,000 people had the right to carry weapons or receive a jury trial. Hundreds of Athenians were killed (they were ordered to drink hemlock) and thousands more were exiled.
The Thirty Tyrants were overthrown by Thrasybulus, with help from Thebes, the following year.
CRITIAS, Athenian orator and poet, and one of the ThirtyTyrants.
He was banished (probably in the democratic reaction of 407) and fled to Thessaly, where he stirred up the Penestae (the helots of Thessaly) against their masters, and endeavoured to establish a democracy.
Returning to Athens he was made ephor by the oligarchical party; and he was the most cruel and unscrupulous of the ThirtyTyrants who in 404 were appointed by the Lacedaemonians.
