The Great Schism had a profound impact on Christianity as it formalized the split between the Roman Catholic Church and the Eastern Orthodox Church in 1054. Disagreements over theological doctrines, ecclesiastical authority, and various cultural factors led to this division. The schism not only shaped religious practices and governance but also influenced political relationships in Europe and beyond. It established distinct identities for each branch of Christianity, ultimately contributing to the fragmentation of Christendom and affecting various aspects of European history and culture.
