Synonyms for the council include the Council of Constantinople II (as the second council held in Constantinople after the Council of Chalcedon) and the Eighth Ecumenical Council (as it was recognized as ecumenical by the Orthodox Church). It is also sometimes referred to as the Photian Council, after the leading theologian and politician of the time, Photius I of Constantinople.
