Carthage

Carthage was a major city-state in Africa in the 9th century BC, the capital of the Carthaginian Empire and the only Mediterranean city as powerful as Rome at the time.

Background
Despite all he has accomplished, Caesar still feels himself to be a king of barbarians, and not an emperor of Rome. In order to progress his Legion into a true successor to the Roman Empire, he needs two things: A city truly deserving of the name Rome, and a force strong enough to test him. The latter would be his Carthage, a challenge worthy of Caesar himself.

Appearances
Carthage is mentioned only in the Fallout: New Vegas Official Game Guide Collector's Edition.
