The Byzantines lost so much land, money and soldiers that they became very weak and begged for help from the Western Europeans. Italy and the Pope sent soldiers and ships to help the Byzantines when the Turks attacked Constantinople in April 1453. The Byzantines were badly outnumbered, however, and the walls of Constantinople were very damaged by cannons used by the Turks. In late May 1453, the Turks captured Constantinople by entering through one of the gates along the walls, and the empire came to an end.
