The armies of Carthage were responsible for the city forging the most powerful empire in the western Mediterranean. Although by tradition, a seafaring nation with a powerful navy, Carthage by necessity, had to employ a land army to further their territorial claims and defend against their enemies. Adopting the weapons and tactics of the Hellenistic kingdoms, Carthage similarly employed mercenary armies from their allies and subject city-states. Military successes came in Africa, Sicily, Spain, and Italy, where armies were led by such celebrated commanders as Hamilcar Barca and Hannibal. The military dominance of Carthage was however, eventually challenged by the rise of Rome, and resulting in defeat during the Second Punic War (218-201 BCE), when the days of Carthage as a regional powerhouse came to an end.
