After losing the First Punic War, Carthage faced a new threat — not from Rome, but from within. In this episode of History with Dad, we unravel the chaos of the Mercenary War: unpaid veterans turn on their employers, civil order collapses, and Carthage finds itself besieged by its own army. We’ll explore how Hamilcar Barca fought to save the republic, why Polybius feared this war more than any other, and how a young Hannibal came of age watching it all. Betrayals, brutality, and a republic on the brink — this is the true cost of losing a war.
