Adrian V

Pope Adrian V (; – 18 August 1276), born Ottobuono de' Fieschi, was the head of the Catholic Church and ruler of the Papal States from 11 July 1276 to his death on 18 August 1276. He was an envoy of Pope Clement IV sent to England in May 1265 who successfully completed his task of resolving disputes between King Henry III of England and his barons. Adrian V was elected pope following the death of Innocent V, but died of natural illness before being ordained to the priesthood.

In the Divine Comedy, Dante meets Adrian V in the fifth terrace of Purgatorio where Adrian V cleanses for the vice of avarice.

Biography Ottobuono belonged to a feudal family of Liguria, the Fieschi, counts of Lavagna. His first clerical position came in 1243, when he was created a papal chaplain. Subsequently, he received several ecclesiastical benefices, becoming archdeacon in Bologna (1244) and Parma (1244/48–1255), canon and chancellor of the cathedral chapter in Reims (1243–1250), canon and dean of the chapter in Piacenza (c. 1247) and canon of the cathedral chapter in Paris (1244/45–1270). In December 1251, he was created Cardinal Deacon of San Adriano by his uncle Pope Innocent IV. He was also archpriest of the patriarchal Liberian Basilica (attested from 1262).

He was sent to England in 1265 by Pope Clement IV to mediate between King Henry III of England and his barons, and to preach the Crusades. Fieschi was related distantly, by affinity, to Henry III; his sister had married Thomas II of Savoy, who was a cousin of Henry's wife, Eleanor of Provence.

He remained in England for several years as the papal legate, serving from October 1265 to July 1268. His diplomatic position was such that his name is still on the oldest extant piece of English statute law, the Statute of Marlborough of 1267, where the formal title mentions as a witness "the Lord Ottobon, at that time legate in England". (Also on this legation was a young diplomat, the future Boniface VIII.) In April 1268 he issued a set of canons, which formed the basis of church law in England until the Protestant Reformation of the sixteenth century.

Under the influence of Charles I of Anjou, he was elected pope to succeed Innocent V on 11 July 1276 but died at Viterbo on 18 August 1276 from illness without ever having been ordained to the priesthood. He is buried there in the church of San Francesco alla Rocca. His funeral monument is attributed to Arnolfo di Cambio. Adrian V was the third pope in the "Year of Four Popes" of 1276.

He annulled Pope Gregory X's bull on the holding of papal conclaves, but died before enacting new regulations.

There exists a lack of historical evidence about Adrian V’s avaricious behavior. Some scholars believe that Dante’s view of Adrian V emanated from reading excerpts from John of Salisbury's Policraticus, in which the author anonymously attributed the behavior of avarice to Adrian IV. Dante likely interpreted the excerpts as referring to Adrian V instead of Adrian IV. Adrian V describes that he had to detach himself from the love of worldly things that came to be after he was assigned the papal sit in the short period he was a pope (Purgatorio 19.106-114).
