<P> The Thirty Tyrants (Ancient Greek: οἱ τριάκοντα τύραννοι, hoi triákonta týrannoi) were a pro-Spartan oligarchy installed in Athens after its defeat in the Peloponnesian War in 404 BCE . Upon Lysander's request, the Thirty were elected as a government, not just as a legislative committee . The Thirty Tyrants maintained power for eight months . Though brief, their reign resulted in the killing of 5% of the Athenian population, the confiscation of citizens' property, and the exile of other democratic supporters . They became known as the "Thirty Tyrants" because of their cruel and oppressive tactics . The two leading members were Critias and Theramenes . </P> <P> With Spartan support, the Thirty established an interim government in Athens . The Thirty were concerned with the revision and / or erasure of democratic laws inscribed on the wall next to the Stoa Basileios . Consequently, the Thirty reduced the rights of Athenian citizens in order to institute an oligarchical regime . The Thirty appointed a council of 500 to serve the judicial functions formerly belonging to all the citizens . However, not all Athenian men had their rights removed . In fact, the Thirty chose 3,000 Athenian men "to share in the government". These hand - selected individuals had the right to carry weapons, to have a jury trial, and to reside within city limits . The list of the selected 3,000 was consistently revised . Although little is known about these 3,000 men ‒ for a complete record was never documented ‒ it is hypothesised that the Thirty appointed these select few as the only men the Thirty could find who were devotedly loyal to their regime . The majority of Athenian citizens did not support the rule of the Thirty . </P>
