The evidence that best supports the historical claim that the East-West Schism did not begin in 1054 CE, but that mutual excommunication was part of an already growing division is the decreasing power of the pope following the end of the Western Roman Empire in 476 CE conflicting with the rise of Byzantine power in the East. This evidence suggests that there were already tensions and divisions between the Eastern and Western churches before the mutual excommunication in 1054 CE.
