How did the Hagia Sophia become a mosque?
Today is the anniversary of an awesome tragedy. On May 29, 1453, Constantinople, once the greatest city in the Christian world, finally fell to the warriors of jihad, after they had tried to conquer it for seven hundred years. In my new book The History of Jihad From Muhammad to ISIS, I recount what happened then. Muslims raided monasteries and convents, emptying them of their inhabitants, and plundered private houses. They entered the Hagia Sophia, which for nearly a thousand years had been the grandest church in Christendom.
