The role of the Great Schism in the history of the Christian church was significant as it divided Christianity into the **Eastern** Orthodox Church and the **Roman Catholic Church** in 1054. The split arose from theological, political, and cultural differences, primarily regarding the authority of the papacy and the filioque clause in the Nicene Creed. The Schism highlighted the increasing divide between the Latin-speaking West and Greek-speaking East, leading to centuries of religious and political conflict, which shaped Christian practices and identities.
