Role in history
Known as the cradle of civilization, the Mediterranean was opened as a highway for commerce by merchants trading from Phoenicia. Over succeeding centuries Carthage, Greece, Sicily, and Rome were rivals competing for dominance of its shores and trade. It was later dominated by the Byzantine Empire and the Arabs; between the 11th and 14th centuries, Barcelona and the Italian city trading states, such as Venice and Genoa, dominated the Mediterranean. Control of its islands, coasts, and trade routes was vital during both World Wars, leading to important campaigns. Since World War II the region has been of great strategic importance to the USA and Western European countries (NATO).
