815 – 843Second Iconoclasm -- Triumph of OrthodoxyThe Second Iconoclasm (815-843) begins under Leo V, who revives the iconoclast policy believing that the military successes of the iconoclast emperors Leo III and Constantine V prove God's approval of icon removal. The Second Iconoclasm ends with the Triumph of Orthodoxy on 11 March 843, when Empress Theodora (regent for her son Michael III) restores icon veneration -- celebrated annually in the Orthodox Church to this day as the first Sunday of Lent. The Patriarch who condemned the previous Patriarch for restoring icons is himself condemned; icons return to the churches.
