A schism is a division or split within a group, often due to differing beliefs or practices. This term is commonly used in religious contexts, where factions may form over theological disagreements. For example, the Great Schism of 1054 divided Christianity into the Roman Catholic Church and the Eastern Orthodox Church. Schisms can also occur in other organizations, such as political parties or social movements, when members disagree on key issues. These divisions can lead to the formation of new groups or sects, each with its own interpretations and goals, impacting the original group's unity and direction.
