Ecumenical Patriarch of Constantinople from 847 to 858 and from 867 to 877
Ignatius of Constantinople was the Ecumenical Patriarch of Constantinople from 847 to 858 and from 867 to 877. Ignatius lived during a complex time for the Byzantine Empire. The Iconoclast Controversy was ongoing, Boris I of Bulgaria converted to Christianity in 864, and the Roman pontiffs repeatedly challenged the ecclesiastical jurisdiction of the Eastern Church in Bulgaria. As patriarch, Ignatius denounced iconoclasm, secured jurisdiction over Bulgaria for the Eastern Church, and played an important role in conflicts over papal supremacy.
