The Seventh Ecumenical Church Council of Nicea (Iznik) (AD 787)

The seventh Ecumenical Church Council was convened by emperor Constantine VI and his mother Irene in 787, about 126 years after the sixth church council. Approximately three hundred and sixty bishops, primarily from the eastern church, met together in the Church of Holy Wisdom (Hagia Sophia) in Nicea (modern Iznik) from September 24 to October 13. Led by Constantinople’s bishop Tarasius, the council approved the use of Christian icons in churches and monasteries.
