Nicholas I: Biography, Facts and Career

Pope Nicholas I (Latin: Nicolaus I; c. 800 – 13 November 867), called Nicholas the Great, was the bishop of Rome and ruler of the Papal States from 24 April 858 until his death on 13 November 867. He is the last of the three popes listed in the Annuario Pontificio with the title "the Great", alongside Leo I and Gregory I. Nicholas is remembered as a consolidator of papal authority, exerting decisive influence on the historical development of the papacy and its position among the Christian nations of Western Europe. Nicholas I asserted that the pope should have suzerainty over all Christians, even royalty, in matters of faith and morals. Nicholas refused King Lothair II of Lotharingia's request for an annulment of his marriage to Teutberga. When a council pronounced in favor of annulment, Nicholas I declared the council deposed, its messengers excommunicated, and its decisions invalid. Despite pressure from the Carolingians, who laid siege to Rome, his decision held. During his reign, relations with the Byzantine Empire soured because of his support for Patriarch Ignatios of Constantinople, who had been removed from his post in favor of Photius I. Since the seventeenth century, Nicholas has been venerated as a saint in the Catholic Church, with his feast on 13 November. His claims of supremacy over territories outside his jurisdiction, the incorporation of the filioque in the Constantinopolitan Nicene creed, and his pressure on Bulgaria to remain under Roman rule, provoked tensions between Rome and Constantinople, leading to his excommunication by the Greeks at the fourth Council of Constantinople.
