Biography[]
Michael was appointed as the Patriarch of Constantinople in 1043, and during his reign he argued extensively with Pope Leo IX, including minor factors such as the use of unleavened bread for the Eucharist and major events such as the takeover of Orthodox Christian churches in southern Italy by Catholic Normans. The disagreements led to the Great Schism of 1054, which would not be solved.
