WI: Ottoman Empire collapses in the early 15th century?
In 1402, Timur defeated the Ottoman Empire at the Battle of Ankara and took its Sultan prisoner, eleven years of civil war followed within the empire. My question is what if the Empire disintegrated during this period? What would the future implications be? Would the Byzantines have a chance to survive?
