Menestheus

Menestheus (Greek: Μενεσθεύς), the son of Peteus, son of Orneus, son of Erechtheus, and either Polyxene or Mnesimache, was a legendary King of Athens during the Trojan War. He was set up as king by the Dioscuri when Theseus travelled to the underworld, and at his return Menestheus exiled him from the city.
