In the Smithsonian Magazine in 2008, Fergus M. Bordewich described the events of 29 May, 1453:
In the 11th century, the Byzantines suffered the first in a series of devastating defeats at the hands of Turkish armies, who surged westward across Anatolia, steadily whittling away at the empire. The realm was further weakened in 1204 when western European crusaders en route to the Holy Land, overtaken by greed, captured and looted Constantinople. The city never fully recovered.
By the mid-15th century, Constantinople was hemmed in by Ottoman-controlled territories. On May 29, 1453, after a seven-week siege, the Turks launched a final assault. Bursting through the city’s defenses and overwhelming its outnumbered defenders, the invaders poured into the streets, sacking churches and palaces, and cutting down anyone who stood in their way. Terrified citizens flocked to Hagia Sophia, hoping that its sacred precincts would protect them, praying desperately that, as an ancient prophesied, an avenging angel would hurtle down to smite the invaders before they reached the great church.
Instead, the sultan’s janissaries battered through the great wood-and-bronze doors, bloody swords in hand, bringing an end to an empire that had endured for 1,123 years. “The scene must have been horrific, like the Devil entering heaven,” says Crowley. “The church was meant to embody heaven on earth, and here were these aliens in turbans and robes, smashing tombs, scattering bones, hacking up icons for their golden frames. Imagine appalling mayhem, screaming wives being ripped from the arms of their husbands, children torn from parents, and then chained and sold into slavery. For the Byzantines, it was the end of the world.” Memory of the catastrophe haunted the Greeks for centuries. Many clung to the legend that the priests who were performing services that day had disappeared into Hagia Sophia’s walls and would someday reappear, restored to life in a reborn Greek empire.
That same afternoon, Constantinople’s new overlord, Sultan Mehmet II, rode triumphantly to the shattered doors of Hagia Sophia. Mehmet was one of the great figures of his age. As ruthless as he was cultivated, the 21-year-old conqueror spoke at least four languages, including Greek, Turkish, Persian and Arabic, as well as some Latin. He was an admirer of European culture and patronized Italian artists, such as the Venetian master Gentile Bellini, who painted him as a bearded, introspective figure swathed in an enormous robe, his small eyes gazing reflectively over an aristocratically arched nose. “He was ambitious, superstitious, very cruel, very intelligent, paranoid and obsessed with world domination,” says Crowley. “His role models were Alexander the Great and Julius Caesar. He saw himself as coming not to destroy the empire, but to become the new Roman emperor.” Later, he would cast medallions that proclaimed him, in Latin, “Imperator Mundi” — “Emperor of the World.”
Before entering the church, Mehmet bent down to scoop up a fistful of earth, pouring it over his head to symbolize his abasement before God. Hagia Sophia was the physical embodiment of imperial power: now it was his. He declared that it was to be protected and was immediately to become a mosque. Calling for an imam to recite the call to prayer, he strode through the handful of terrified Greeks who had not already been carted off to slavery, offering mercy to some. Mehmet then climbed onto the altar and bowed down to pray.
Among Christians elsewhere, reports that Byzantium had fallen sparked widespread anxiety that Europe would be overrun by a wave of militant Islam. “It was a 9/11 moment,” says Crowley. “People wept in the streets of Rome. There was mass panic. People long afterward remembered exactly where they were when they heard the news.” The “terrible Turk,” a slur popularized in diatribes disseminated across Europe by the newly invented printing press, soon became a synonym for savagery.
