We will begin in 476 with the fall of Rome and will end in 1453, with the fall of New Rome (Constantinople). In between, we will trace the different trajectories that the area stretching from Iceland to Iran traveled along over the course of this fateful millennium. We will meet Northern barbarians, Arab armies, Vikings, Crusaders, Mongols, and the Ottomans; we will witness the birth of Islam and medieval Islamic civilization; Charlemagne’s creation of the Western Roman empire; will see clashes between Popes and rulers and Caliphs and Muslim religious authorities. We will do all this and more, all the while asking: what were the Middle Ages?
