In 149 B.C., after Carthage technically broke its treaty with Rome by declaring war against the neighboring state of Numidia, the Romans sent an army to North Africa, beginning the Third Punic War.The Third Punic War ended in victory for the Romans and defeat for the Carthaginians. Throughout the siege, Hasdrubal attempted to negotiate with the Romans.The destruction of Carthage was an act of Roman aggression prompted as much by motives of revenge for earlier wars as by greed for the rich farming lands around the city. The Carthaginian defeat was total and absolute, instilling fear and horror into Rome's enemies and allies.The immediate cause of the war was the issue of control of the independent Sicilian city state of Messana (modern Messina). In 264 BC Carthage and Rome went to war, starting the First Punic War.
One major event that occurred in the Third Punic War was that "Roman captured and defeated of Carthage," since this ultimately led to the Carthage Empire in the Mediterranean.
