When Rome was still in its infancy, Carthage was the dominant power of the Mediterranean. However, as Rome grew, Carthage remained its rival.
The city of Carthage had two rivals for much of its history. Those were the Greeks in Sicily, and the Roman Republic. The result was the long Sicilian Wars, and then the Punic wars with Romans.
Rome and Carthage battled for many years, resulting in the First, Second, and Third Punic War. The third one essentially ended the history of the city. The Third Punic War consisted of a single-main action, which was the battle of Carthage. The battle resulted with the complete destruction of the city, the annexation of all remaining territory by Rome, and the death or enslavement of thousands of Carthagians.
Not a single building was left standing when Romans left the city of Carthage. This documentary features an archeological dig by Dr. Richard Miles of Cambridge University, showing fresh evidence about the Roman holocaust in Carthage.
