What two areas of the world fought for dominance in the Mediterranean region?

The two primary areas that fought for dominance in the Mediterranean region were the Roman Empire and the Greek city-states during antiquity, followed by the Byzantine Empire and various Islamic caliphates during the Middle Ages. The competition for control over trade routes, resources, and territorial expansion often led to conflicts such as the Punic Wars between Rome and Carthage. Later, the rivalry continued with the Byzantine Empire facing challenges from emerging Islamic powers. These conflicts significantly shaped the cultural and political landscape of the Mediterranean throughout history.
