What was the development and progress of the Great Schism?

The Great Schism, which formally occurred in 1054, was the culmination of centuries of growing tensions between the Eastern Orthodox Church and the Roman Catholic Church. Key issues included disputes over papal authority, the filioque clause in the Nicene Creed, and cultural differences between the Latin West and the Greek East. The excommunication of the Patriarch of Constantinople, Michael Cerularius, by Pope Leo IX, and the subsequent response of Cerularius, marked the official split. Over time, this division solidified into distinct religious traditions, with both churches further developing their theological and liturgical practices independently.
