answer: The Mytilenean revolt was an incident in the Peloponnesian War where Mytilene, a city on the island of Lesbos, attempted to unify the island under its rule and revolt against the Athenian Empire.  The revolt was planned in concert with Sparta and others, but ultimately failed due to Athenian intervention and a lack of Spartan support.
