Justinian I, who took power in 527 and would rule until his death in 565, was the first great ruler of the Byzantine Empire. Located on the European side of the Bosporus (the strait linking the Black Sea to the Mediterranean), the site of Byzantium was ideally located to serve as a transit and trade point between Europe and Asia.Įven after the Islamic empire absorbed Alexandria, Antioch and Jerusalem in the seventh century, the Byzantine emperor would remain the spiritual leader of most eastern Christians. The term “Byzantine” derives from Byzantium, an ancient Greek colony founded by a man named Byzas. The Byzantine Empire finally fell in 1453, after an Ottoman army stormed Constantinople during the reign of Constantine XI. Though the western half of the Roman Empire crumbled and fell in 476 A.D., the eastern half survived for 1,000 more years, spawning a rich tradition of art, literature and learning and serving as a military buffer between Europe and Asia. The Byzantine Empire was a vast and powerful civilization with origins that can be traced to 330 A.D., when the Roman emperor Constantine I dedicated a “New Rome” on the site of the ancient Greek colony of Byzantium.
