Hippias (tyrant)
His brother Cleisthenes was murdered in 514 BC. Hippias' behavior changed. He became cruel and angry, executing people in revenge, and taking away the freedom of people. He also was afraid of threats from the aristocrats. In the end his uncle Cleisthenes decided to overthrow Hippias and gain power for himself and his family. Hippias was captured and sent into exile, away from Athens forever in 510 BC.
