And so they decide to take Constantinople themselves. And as we mentioned in other videos, this is really the dagger in the heart between the relationship between the East and the West. We already talked about the Great Schism of 1054, but now you have the West, who are followers of the Latin Church, which eventually gets known as the Roman Catholic Church. They are sacking Constantinople, the capital of the Byzantine, or the Eastern Roman Empire, the most important city in Eastern Christendom. And once they successfully sack the city in bloody fashion, they break up the Byzantine Empire amongst themselves. And you can see how they break it up. So the Fourth Crusade had very little effect on the actual Holy Land, but it does cause a temporary end to the Byzantine Empire.
