In Greek mythology, Eteocles (/ɪˈtiːəkliːz/; ‹See Tfd›Greek: Ἐτεοκλῆς) was a king of Thebes, the son of Oedipus and either Jocasta[1] or Euryganeia. Oedipus killed his father Laius and married his mother without knowing his relationship to either. When the relationship was revealed, he was expelled from Thebes. The rule passed to his sons Eteocles and Polynices. However, because of a curse from their father, the two brothers did not share the rule peacefully and died as a result, ultimately killing each other in battle for control of the city. Upon his death, Eteocles was succeeded by his uncle, Creon.
