Why did the Crusaders sack Constantinople in 1204? the destruction of the Byzantine Empire and its dramatic collapse under the weight of Mehmed the Conquerer’s spectacular invasion is not necessarily the first or only catastrophe staining the history of Constantinople today. In fact, possibly even more devastating, was not the siege of the Byzantine capital by the Ottomans in the 15th century, but instead, the sacking of Constantinople in 1204 by the Crusaders. ♦Consider supporting the Channel: https://www.patreon.com/Knowledgia ♦Please consider to SUBSCRIBE: https://goo.gl/YJNqek ♦Music by Epidemic Sound ♦Script & Research : Skylar Gordon #History #Documentary #Crusade
