armed expedition against Constantinople
The Fourth Crusade was an armed expedition launched in the early 13th century that was intended to reclaim Jerusalem from Muslim control but instead turned against Constantinople, the capital of the Byzantine Christian Empire. It matters historically because it resulted in the conquest and sacking of Constantinople, fundamentally weakening the Byzantine Empire and altering the religious and political landscape of the medieval Mediterranean world.
