The Second Council of Nicaea is believed to have been the Seventh Ecumenical Council by Roman Catholics, Eastern Orthodox, Old Catholics, and various other Western Christian groups. It met in AD 787 in Nicaea (site of the First Council of Nicaea; present-day İznik in Turkey) to restore the honoring of icons (or, holy images),[1] which had been suppressed by imperial edict inside the Byzantine Empire during the reign of Leo III (717 - 741). His son, Constantine V (741 - 775), had held a synod to make the suppression official.
