Pope Cosmas III of Alexandria was the 58th Pope of Alexandria and Patriarch of the See of St. Mark from 920 to 932.[1] [2]
According to the History of the Patriarchs of Alexandria, after Abuna Peter of the Ethiopian Orthodox Church had become embroiled in a civil war and was forced into exile, and the Emperor of Ethiopia requested a new Abuna to replace him, Cosmas III refused to ordain a new Abuna because Peter was still alive. This led to strained relations between the two powers.
