The Roman Empire died in 1453 because the Ottoman Turks had gunpowder cannons. I am not anybody predicted that considering the Arabs could have likely finished off the Roman Empire immediately after finishing off the crusader states. The Mongols absolutely could have finished off the Roman Empire but just weren’t interested after bouncing off Palestine. Before that the early Muslims could have finished off the Roman Empire has Khalid Ibn Al Walid not been sacked by his cousin. With so many near death experiences actually death was challenging to guess at.
