Simon Mayall will focus on some of the most significant clashes of arms in human history: the taking and retaking of Jerusalem and the collapse of the Crusader states; the fall of Constantinople; the sieges of Rhodes and Malta; the assault on Vienna and the ‘high-water mark’ of Ottoman advance into Europe; culminating in the Allied capture of Jerusalem in World War I, the final collapse of the Ottoman Empire, the dissolution of the sultanate and the caliphate, and the formation of modern Europe and the modern Middle East.
