The expansion is attributed chiefly to the second half of the 3rd century B.C., and to the genius of the Carthaginian statesman, Hamilcar Barca, who, seeing his country deprived by Rome of her trading dominion in Sicily and Sardinia, used Spain, not only~ as a source of commercial wealth, but as an inexhaustible supply of warlike troops to serve in.
Later, in the First Punic War, Hamilcar Barca was encamped for three years on Hiercte or Pellegrino, but the Roman possession of the city was not disturbed.
They certainly joined in the revolt of the Gauls under Hamilcar (200), but after they had been defeated by the consul Gaius Cornelius (197) they finally submitted.
There were Siceliots who played the part of the Medizers in Greece: Selinus was on the side of Carthage, and the coming of Hamilcar was immediately brought about by a tyrant of Himera driven out by Thero.
Her leader was Hannibal, grandson and avenger of the Hamilcar who had died at Himera.
