The Great Schism of 1054, which divided Christianity into Roman Catholicism and Eastern Orthodoxy, had profound consequences. The split was largely based on theological disagreements, such as the nature of the Holy Spirit and the authority of the Pope. It solidified differing practices and beliefs, leading to religious fragmentation and political tensions between the Eastern Byzantine Empire and Western Europe. This division influenced the development of distinct Christian cultures and rituals while fostering a sense of rivalry that persisted for centuries. The schism also laid the groundwork for later religious reformations and changes in power dynamics within Europe, affecting the continent’s socio-political landscape.
