How did the Fourth Crusade contribute to further division within Christianity?

The Fourth Crusade contributed to further division within Christianity, as the Crusade was called upon to aid the Eastern Christians in retaking and holding onto the Holy Land. However, the Western Christians, on their march towards the Holy Land, instead decided to attack and loot Constantinople following a failed Crusader-back coup. This led to broken relations between the East and Western Christians, as not only has the Crusade failed in its original purpose, but it also fragmented the power structure of the Eastern Roman Empire.
