After being defeated in the First Punic War, Carthage was reduced to an African city-state. Its remarkable revival was initiated by Hamilcar Barca, the most successful Carthaginian general and de facto ruler of the republic. Hamilcar and his family, the Barcids, conquered a new empire in Spain. In 221 BCE, Hannibal Barca, son of Hamilcar, came to power in Spain and Carthage. Inheriting the superb army that his Barcid predecessors had built, he immediately showed flashes of genius. Then, in 220 BCE, he received a fateful embassy from Rome.
