The raid of the Po Valley in 203 BC was the culmination of a major war, carried out by the Carthaginian commander Mago, son of Hamilcar Barca, at the end of the Second Punic war between Rome and which location, that was a Phoenician city-state, during the 7th to 3rd centuries BC?
Ancient Carthage Carthage (Punic: 𐤒𐤓𐤕•𐤇𐤃𐤔𐤕 , "Qart-ḥadašt " "new city") was the Phoenician city-state of Carthage and during the 7th to 3rd centuries BC, included its sphere of influence, the Carthaginian Empire. The empire extended over much of the coast of North Africa as well as encompassing substantial parts of coastal Iberia and the islands of the western Mediterranean Sea.
Cirta Cirta (from Berber: KRTN or Kirthan, Phoenician: "Tzirta" ) was the capital city of the Berber Kingdom of Numidia in northern Africa (modern Algeria). Its strategically important port city was Russicada. Although Numidia was a key ally of the ancient Roman Republic during the Punic Wars (264–146 BC), Cirta was subject to Roman invasions during the 1st and 2nd centuries BC. Eventually it went under Roman dominion during the rule of Julius Caesar. Cirta was then repopulated by Roman colonists by Caesar and Augustus and was surrounded by a "Confederation of free Roman cities" (Tiddis, Cuicul, Milevum, etc.) The city was destroyed in the beginning of the 4th century and was rebuilt by the Roman emperor Constantine the Great, who gave his name to the newly constructed city, Constantine. Vandals damaged Cirta, but emperor Justinianus I reconquered and improved the Roman city. Arabs finally captured it in 698 AD.
