Via 123rf
The fall of Constantinople came after a 53-day siege by the then 21-year-old Ottoman Sultan Mehmed II, who fittingly took the title Mehmed the Conqueror. Constantinople was not just any city; it was the preeminent city in the world and had been an imperial capital for sixteen centuries. It had been the capital of the Roman Empire since 330 A.D.
The fall of the city was considered a massive boon to Islam and a blow to Christendom. Previously considered instrumental in the spread of Christianity and even named after the Roman Emperor Constantine, after the Ottoman conquest the city became a stronghold for Islam. The seizure of Constantinople became a precursor to further Ottoman expansion into Europe. Mehmed was even able to claim the title “Caesar,” since whoever possessed the imperial capital controlled the empire. The siege also marked one of the first times that artillery was used in combat, and the recapture of Constantinople remained a Christian pipe dream for many years after, though the Age of Crusading was at an end. The waves of Byzantine scholars and refugees following the sack of Constantinople had an impact on the Renaissance, bringing accumulated knowledge of the Greeks and Romans to Western Europe.
