context: the retirement of the indemnity removed one of the main incentives the Romans had to keep the peace with Carthage – there were no further payments that might be interrupted. The Romans had other reasons to conquer Carthage and her remaining territories. By the middle of the 2nd century BC, the population of the city of Rome was about 400,000 and rising. Feeding the growing populace was becoming a major challenge.
