Ismenias

Ismenias (Ancient Greek: Ἰσμηνίας) was an ancient Theban politician of the 4th century BC, leader of the Theban democratic faction.

He rose to power in 403 BC, a year after the end of the Peloponnesian War, and pursued an anti-Spartan policy, which included harboring exiles fleeing from the Thirty Tyrants in Athens. In 382 BC, during a Spartan occupation of Thebes, he was identified, along with Androcleides, as one of the leaders of the anti-Spartan faction. He was imprisoned and executed for Medism.
