The Philaidae or Philaids (Ancient Greek: Φιλαΐδαι) were a powerful noble family of ancient Athens. They were conservative land owning aristocrats and many of them were very wealthy. The Philaidae produced two of the most famous generals in Athenian history: Miltiades the Younger and Cimon.
The Philaids claimed descent from the mythological Philaeus, son of Ajax. The family originally came from Brauron in Attica. Later a prominent branch of the clan were based at Lakiadae west of Athens. In the late 7th century BC a Philaid called Agamestor married the daughter of Cypselus, the powerful tyrant of Corinth. In 597 BC a man named Cypselus was archon of Athens. This Cypselus was probably grandson of the Corinthian tyrant of the same name and son of Agamestor.
Some years before 566 BC, a member of the Philaid clan, Hippocleides, was a suitor for the hand of Agariste, the daughter of the influential tyrant of Sicyon, Cleisthenes. However Hippocleides lost out to Megacles from the rival Alcmaeonid clan when Cleisthenes was unimpressed with a drunken Hippocleides who stood on his head and kicked his heels in the air at a banquet.[1]
