Latin Empire

The Latin Empire was a feudal crusader state. It was created during the Fourth Crusade on the land captured from the Byzantine Empire. Originally, the crusaders were told to retake the Muslim-controlled city of Jerusalem. Instead of doing that, the crusaders looted and captured Constantinople.
