The Fourth Crusade (1202-1204 CE) was called by Pope Innocent III (r. 1198-1216 CE) to retake Jerusalem from its current Muslim overlords. However, in a bizarre combination of cock-ups, financial constraints, and Venetian trading ambitions, the target ended up being Constantinople, capital of the Byzantine Empire and the greatest Christian city in the world. Sacked on 12 April 1204 CE, Constantinople was stripped of its riches, relics, and artworks, and the Byzantine Empire was divided up between Venice and its allies. The Fourth Crusade thus gained its infamous reputation as the most cynical and profit-seeking of all the crusades.
