The Roman Empire is undeniably the most powerful nation in the Mediterranean, controlling Anatolia, Italy, The Balkan Peninsula, Egypt, and the rest of North Africa. However there was one moment in history when the empire seemed on the verge of losing everything, Islam had risen in Arabia and attacked the empire and Persia, but despite the weakness of the empire after years of war with the Persians they managed to rally and push the Arabs back out of their territory. The persians fell but over the next few centuries Arabia was conquered (though it eventually became an independent republic in the 1600s AD) and the Romans made their dominance over persia clear later on. But what would have happened if the Arabs had managed to defeat both the Romans and the Persians? How woud this effect the history of the mediterranian and the rest of the world?
