Battle of Himera (480 BC), supposedly fought on the same day as the more famous Battle of Salamis, or at the same time as the Battle of Thermopylae, saw the Greek forces of Gelon, King of Syracuse, and Theron, tyrant of Agrigentum, defeat the Carthaginian force of Hamilcar the Magonid, ending a Carthaginian bid to restore the deposed tyrant of Himera.
