Agathocles of Syracuse
In 278 BC, soon after disembarking his army in Sicily, he lifted the Carthaginian Siege of Syracuse. Pyrrhus was proclaimed king of Sicily. He was already making plans for his son Helenus, a grandson of Agathocles of Syracuse through his mother, to inherit the kingdom of Sicily and his other son Alexander to be given Italy. In 277 BC, Pyrrhus captured Eryx, the strongest Carthaginian fortress in Sicily. This prompted the rest of the Carthaginian-controlled cities to defect to Pyrrhus.
