Ephialtes

Ephialtes was an ancient Athenian politician and an early leader of the democratic movement there. In the late 460s BC, he oversaw reforms that diminished the power of the Areopagus, a traditional bastion of conservatism, and which are considered by many modern historians to mark the beginning of the radical democracy for which Athens would become famous. These powers included the scrutiny and control of office holders, and the judicial functions in state trials. He reduced the property qualifications for holding a public office, and created a new definition of citizenship. In 461 BCE, he was assassinated. Although it remains uncertain who exactly killed him, it is believed to likely be at the instigation of his oligarch opponents. In the wake of his death, the political leadership of Athens passed to his deputy, Pericles.
