Innocent V

Pope Innocent V (Latin: Innocentius V; c. 1225 – 22 June 1276), born Pierre de Tarentaise, was head of the Catholic Church and ruler of the Papal States from 21 January to 22 June 1276. A member of the Order of Preachers, he acquired a reputation as an effective preacher. He held one of the two "Dominican Chairs" at the University of Paris, and was instrumental in helping with drawing up the "program of studies" for the Order. In 1269, Peter of Tarentaise was Provincial of the French Province of Dominicans. He was a close collaborator of Pope Gregory X, who named him Bishop of Ostia and raised him to cardinal in 1273.

Upon the death of Gregory in 1276, Peter was elected pope, taking the name Innocent V and becoming the first pope elected in a papal conclave. He died about five months later, but during his brief tenure facilitated a peace between Genoa and King Charles I of Sicily. Pope Innocent V was beatified in 1898 by Pope Leo XIII.
