The Battle of Zama in 202 BC ended the Second Punic War and established Roman dominance over the western Mediterranean for the next three centuries. It was the only battle Hannibal ever lost in a pitched field engagement, and it was lost to the one Roman general who had studied his methods carefully enough to use them against him. Scipio Africanus was thirty-four years old when he defeated Hannibal at Zama. He had spent his career learning from Carthage’s mistakes and Rome’s. The education was complete.
