The Fourth Crusade originally aimed to retake Egypt from Muslim control, but ended up invading Christian cities instead. The Crusaders made an agreement with Venice for transportation to Egypt, but were forced to first attack the Christian city of Zara in order to pay for the voyage. They then turned on Constantinople, sacking the city and brutally killing its inhabitants. The Crusade ultimately established Latin states across the former Byzantine Empire, though resistance from remaining Byzantine territories eventually overthrew the crusader rule.
