The Sack of Constantinople in 1204 during the Fourth Crusade is a defining moment in history. Crusaders, diverging from their mission to reclaim Jerusalem, besieged the Byzantine capital, leading to the desecration of sacred sites, theft of relics, and a profound shift in the balance of power in the eastern Mediterranean. This event marked a betrayal of Christian unity and had lasting effects on the Byzantine Empire.
