Adrastus

Adrastus, a king of Argos, whose daughter married Polynices of Thebes, who had been exiled from his native city by his brother Eteocles. He led the expedition of the 'Seven against Thebes' to restore his son-in-law to his right, and was the only one that survived, as Amphiarus had foretold. Ten years later he led the six sons of the heroes that had fallen to a new attack on Thebes—the war of the Epigōni ('descendants'). This time the attack was successful, but a son of Adrastus fell in the struggle, and the father immediately died of grief.
