Carthage was founded in 814 BC by Phoenician settlers from the city of Tyre, bringing with them the city-god Melqart. Ancient Carthage was an informal hegemony of Phoenician city-states throughout North Africa and modern Spain from 575 BC until 146 BC. It was more or less under the control of the city-state of Carthage after the fall of Tyre to Babylonian forces. At the height of the city's influence, its empire included most of the western Mediterranean. The empire was in a constant state of struggle with the Roman Republic, which led to a series of conflicts known as the Punic Wars. After the third and final Punic War, Carthage was destroyed then occupied by Roman forces. Nearly all of the territory held by Carthage fell into Roman hands.
