149-146 BC Carthage was continually being plundered by neighboring tribes who knew the Carthagians couldn't cross Roman laid borders. Carthage was fed up and took up arms against the intruders. Rome was jealous of Carthage's growing wealth and trade. With Cato's slogan "Carthago delenda est" and Carthage's violation of their treaty, Rome invaded. Rome, leveled the walls, set fire to the city, sold the citizens into slavery, and salted the land. This ended Carthage and its conflicts with Rome.
