Third Punic War (149-146 B.C.)Third Punic War (149-146 B.C.) - By the Third Punic War, Carthage was no longer able to project power the way it had in the first two. Nevertheless, it managed to regain much of its economic might, and that was enough to worry Rome. As part of the peace treaty ending the Second Punic War, Carthage was required to get Roman approval before it could go to war, even to defend itself. And it was this stipulation that Rome used as a pretext to attack and ultimately wipe Carthage off the map. In 151 B.C., Numidia was encroaching on what little land Carthage still controlled. Carthage responded by attacking its neighbor. Rome viewed this as a breach of the treaty and declared war on Carthage in 149. It was a one-sided affair. The Roman army invaded Africa and besieged the city. The Carthaginians defended their home valiantly, repelling Rome for three years. But in 146 B.C., the city fell. Rome dealt harshly with the vanquished. Most of the city's population was killed in the assault, but approximately 50,000 citizens survived. They were summarily sold into slavery and Carthage was utterly destroyed. A popular myth arose centuries later that the Romans sowed the crops with salt in order prevent anything from growing on the site for generations. There's no truth to this (so far as we know). None of the Roman historians mentions it in their writings and the Romans themselves used this fertile land to raise crops to help feed its growing empire in the following years. Rome now had no adversaries left in the western Mediterranean, and would soon turn its attention east. After 668 years, one of antiquity's greatest cities, Carthage, passed into history.
