The western Phoenicians were arranged into a multitude of self-governing city-states. Carthage had grown to be the largest and most powerful of these city-states by the fifth century BC and gained increasingly close control over Punic Sicily and Sardinia in the fourth century BC, but other communities remained outside their control. In the course of the Punic wars (264–146 BC), the Romans challenged Carthaginian hegemony in the western Mediterranean, culminating in the destruction of Carthage in 146 BC, but the Punic language and Punic culture endured under Roman rule, surviving in some places until Late Antiquity.
