Which famous empire conquered rome and the mediterrenean basin?

Answer 1

What comes closest to what you describe is the Ottoman Empire. However, the Ottomans did not conquer Rome and did not take over the whole of the Mediterranean. They defeated the Byzantine Empire by taking its capital, Constantinople. Byzantine Empire is the name historians use for the Eastern Roman Empire after the fall of the Western Roman Empire. The west had already fallen more than 1000 years earlier. Also note that the city of Rome itself had never been conquered by anyone. The Ottomans conquered the Middle East and North Africa. On the European shores of the Mediterranean they only took over Greece and Albania. Apart form this, Mediterranean Europe was not reached by the Ottomans.
