How did the split of the Roman Catholic Church and the Byzantine Empire Church affect people living in Europe?

The split between the Roman Catholic Church and the Byzantine Empire Church, known as the Great Schism of 1054, significantly impacted people in Europe by creating a religious divide that influenced cultural, political, and social dynamics. It led to the establishment of distinct religious practices and beliefs, contributing to the emergence of national identities, particularly in the West and East. This division also intensified conflicts, such as the Crusades, and shaped alliances, as different regions aligned with either the Catholic or Orthodox faith. Overall, the schism deepened existing divisions and set the stage for future religious conflicts in Europe.
