After the Third Punic War, new geographic divisions emerged between the Romans and the neighbouring societies. A physical barrier between the Roman province of Africa and Numidian territory was called fossa regia (‘the royal ditch’).
Within the province, the Romans continued to tax citizens in the same way that Carthage had. The previously Carthaginian areas that Rome acquired after the First, Second, and Third Punic Wars were some of the first overseas territories that Rome had administered, and Roman tax policies in these areas and throughout their territory, may have been based partly on Carthaginian taxes.
The Third Punic War had resulted in the destruction of most of Carthage as a city, including the majority of the architecture. However, some ruins do still exist in Tunisia today. The walled area of Byrsa and the military and trading ports can be seen in the ruins!
