The Fall of Constantinople by the Ottoman army happened on May 29, 1453, it took 53 days because the Ottoman Army did a siege that began on April 6th.
An ambassador was sent to Constantinople to offer a lift of the siege if they gave up on it, this way the Emperor and the inhabitants would leave with their possessions, or they could remain in the city if they wanted. This was not accepted. On May 29 an all-out offensive began, and they were able to take the city. They used “bronze bombards” at the siege so they could breach the city’s walls.
