invasion attempts before 1453, but with each fight it got weakened. This
resulted in the fall of Constantinople in the year 1453, at the hands of
Ottoman Turks. Constantinople was not only fighting against the Turks, but also

resistance they put up against the several external aggressors. If that has
been the case, then they would not have been defeated by the Ottoman Turks.
