Returning to the narrative, Hamilcar Barca, continuing his campaigns into the Spanish interior, died suddenly battling against hostile tribes in 228 BC. With Hamilcar's eldest son, the famous Hannibal, still in his teens, Hamilcar's son-in-law, Hasdrubal the Fair, succeeded the great Barcid leader in Spain. Charming, sophisticated, and diplomatic, Hasdrubal consolidated Hamilcar's foothold in southern Spain by a series of treaties, guest-friendships, and political marriages along with occasional judicious campaigns. His newly-established capital, New Carthage, quickly grew to be one of the greatest cities of the burgeoning Carthaginian empire due to its natural harbor and ready access to the markets of Spain and North Africa. By the time of Hasdrubal's own death in 221 BC, the Carthaginian army and cities in Spain had been forged into a formidable power base which would serve the young Hannibal well in the trials to come.
