In the classical period, Spain was a mix of Celtic and Iberian tribal states, and Greek and Phoenician trading ports, with the largest state being the kingdom of Tartessus. With the eruption of war between Carthage, a Phoenician colony in North Africa and the Greeks, the Carthaginians begin extending their influence in Iberia, creating the city of New Carthage (Cartagena), in hopes of creating a trading empire. Following the First Punic War with Rome, in 237 BC, Hamilcar Barca, the famous Carthaginian general, then began the conquest of Turdetania (the successor state of Tartessus) and Gades to provide a springboard for further attacks on Rome. Hamilcar entrusted the conquest and military governance of the region to his son Hasdrubal the Fair – his other son, Hannibal, would march his troops across Hispania with elephants to lead them on Rome in the Second Punic War. During that war, Rome declared Hispania to be a Roman "provincia" in 218 BC, beginning a century-long campaign to subdue the people of Iberia to Roman.
