The Fourth Council of Constantinople of 879-880 is the Eighth Ecumenical Council for Eastern Orthodox Christians. Photios, a noble layman, had been appointed Patriarch of Constantinople but deposed by a Council of Constantinople called in 869 by Emperor Basil I the Macedonian and Pope Adrian II. Called in 879, this Greek Fourth Council of Constantinople, held after Photios had been reinstated on order of the Emperor, annulled the earlier one. Today, the Roman Catholic Church recognizes the council in 869-870 as "Constantinople IV", while the Eastern Orthodox Churches recognize the councils in 879-880 as "Constantinople IV" and revere Photios as a saint. At the time that these councils were being held, this division was not yet clear.
