The economic recovery of Carthage after the first Punic Was is usually attributed to the Expansion into the Iberian Peninsula. Spain was rich in Natrual resources and had many silver mines to help pay for Mercenaries. The city of Cartagena or Carthago Nova, became a 2nd Capital for the Carthaginians, providing an excellent port, trade hub and defensible city. Spain also fixed Carthage's manpower issue, as they could recruit from the Spanish tribes as well as hire their regular Mercenaries.
