Icon of person Ephialtes

Ephialtes (Greek: Ἐφιάλτης, Ephialtēs) 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. Read more on Wikipedia
