Answer:
Carthage and Rome were two of the most powerful countries at the time. The time between 264-146 BCE was call the Punic wars, there was three Punic wars. The first Punic war started with expansion in Sicily (right next to the boot of Italy) Sicily started the first Punic war. Rome was the victor of the first Punic war and put on some big prices on the Carthage government, so Carthage went to Spain to get some silver to pay their debt to Rome. When Hannibal sacked one of Romes allies the Romans demanding to Carthage to hand over Hannibal, when Carthage said no they declared war. Rome again won this war and put some agreement on Carthage government. The third Punic War began after Carthage deviated from its agreement with Rome that it would give up its fleet and refrain from invasions. I'm sorry if this does not make a lot of seance but I will give you some videos to better answer your question. It's kind of hard to cover a century of history so bare with.
If you check out Invicta The First Punic War they did a four part video about the first Punic war. If you check out HistoryMarche they go into Hannibal and the Second Punic War. If you check out Extra History they go over all three wars and talk about the 3rd Punic war. Not much is known about the third Punic war so you won't find a lot of info about it other than Carthage was burned to the ground after several years of besieging it. I tried to answer to the best of my knowledge hope the channels help you if I didn't.
