Answer - A - During the 1400s, capturing Constantinople was the greatest military triumph of the Ottoman Empire.

Key Takeaway: The Fall of Constantinople was the capture of the capital of the Byzantine Empire that occurred after a siege laid by the Ottoman Empire under the command of Sultan Mehmed II. The siege lasted from April 5, 1453 until May 29, when the city fell to the Ottomans. Constantinople was defended by the army of Emperor Constantine XI. This event was a military triumph for the Ottomans, marking the end of the political independence of the millennium-old Byzantine Empire, which was by then already fragmented into several Greek monarchies.
