Answer:
The Punic Wars were wars that took place between Rome and Carthage. Eventually, Rome won the war and destroyed Carthage, as a result, Rome controlled Sicily and Corsica, and eventually Greece. and it emerged as a naval and land power. With that, Rome became a dominant power in the Mediterranian and around it.
When Rome took over Carthage there was a huge amount of resources that were available to the Romans, so it also helped them to expand the Empire.
But the wars demanded sacrifice from Romans, because of the length of the war, it changed the Roman social structure deeply, the rich got richer and the poor got poorer, which also eventually led to social unrest.
