Policital leadership of athens was passed to a decendant of what powerful and historically influential family?
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. He introduced pay for public officeholders, reduced the property qualifications for holding a public office, and created a new definition of citizenship. Ephialtes, however, would not live to participate in this new form of government for long. In 461 BC, he was assassinated, probably at the instigation of resentful oligarchs, and the political leadership of Athens passed to his deputy, Pericles.
Bryennios Bryennios or Bryennius (Greek: Βρυέννιος ), feminine form Bryennissa (Βρυέννισσα), was the name of a noble Byzantine family which rose to prominence in the 11th and 12th centuries, mostly as military commanders. The etymology of the name is uncertain. The first members of the family appear in the 9th century, with the "strategos" Theoktistos Bryennios. None are known for the 10th, but they reappear in the latter half of the 11th century, when they rose to high military commands and became associated with the Komnenian dynasty. Members of the family retained high positions through the 12th century, and are documented up to the 15th century.
