Final answer:
The Third Punic War ended with a decisive Roman victory and resulted in the complete destruction of Carthage, effectively ending the city's existence as a political entity.
Step-by-step explanation:
The conflict known as the Third Punic War that transpired from 149-146 BC between Rome and Carthage concluded with a definitive Roman victory, culminating in the destruction of Carthage.
Despite an uneasy peace following earlier wars, antagonism persisted, leading to Cato the Elder's declaration that 'Carthage must be destroyed.' Provoked into war, Rome decisively defeated Carthage, leading to a significant loss of life, the selling of survivors into slavery, and the leveling of the city. Carthage's fall allowed Rome to establish a new province in Africa, with Tunis as its capital.
