The Siege of Constantinople in 1453 - Primary Sources and Articles
One of the most important events in world history, the fall of Constantinople marked the end of the Byzantine Empire and the beginning of the Ottoman. In 1453, Mehmed II (1451-1481), the Ottoman Sultan historically known as Mehmed the Conqueror, led an army of 150,000 Turks which besieged Constantinople from April 5th to May 29th, 1453. In the final assault the Byzantine Emperor Constantine IX was killed, and the city fell. Several accounts of this battle exist and we will attempt to republish as many different accounts as possible.
