Pope Honorius IV (c. 1210 – April 3, 1287), born Giacomo Savelli, was Pope for two years from 1285 to 1287. During his unremarkable pontificate he largely continued to pursue the pro-French policy of his predecessor, Pope Martin IV (1281–85). He was the last Pope who was married before he took Holy Orders.
He studied at the University of Paris, during which time he held a prebend and a canonry at the cathedral of Châlons-sur-Marne. Later he obtained the benefice of rector at the church of Berton, in the diocese of Norwich, in England, a nation he never visited.
In 1261 he was created Cardinal Deacon of Santa Maria in Cosmedin by Pope Urban IV (1261–64), who also appointed him papal prefect in Tuscany and captain of the papal army. Cardinal Savelli pursued a diplomatic career. Pope Clement IV (1265–68) sent him and three other cardinals to invest Charles of Anjou as King of Sicily at Rome on 28 July, 1265. After the long deadlocked vacancy in the papal see after Clement IV's death, a vacant seat of three years, he was one of the six cardinals who finally elected Pope Gregory X (1271–1276) by compromise on 1 September, 1271, in a conclave held at Viterbo because conditions in Rome were too turbulent.
In 1274 he accompanied Gregory X to the Council of Lyon where it was established that only four mendicant orders were to be tolerated: Dominicans, Franciscans, Augustinians and Carmelites. In July, 1276, he was one of the three cardinals whom Pope Adrian V (1276) sent to Viterbo with instructions to treat with the German King, Rudolf I of Habsburg (1273–1291), concerning his imperial coronation at Rome and his future relations towards Charles of Anjou, whom papal policy supported. The death of Adrian V in the following month rendered fruitless the negotiations with Rudolf I.
Sicilian affairs required immediate attention. Previously, under Martin IV, the Sicilians had rejected the rule of Charles of Anjou, taking Peter III of Aragon (1276–85) as their King without the consent and approval of the Pope.
The massacre of 31 March, 1282, known as the Sicilian Vespers, had precluded any reconciliation; Martin IV put Sicily and Pedro III under an interdict, deprived Pedro III of the Kingdom of Aragon, and gave it to Charles of Valois, the younger of the sons of King Philip III of France (1270–85) whom he assisted in his attempts to recover Sicily by force of arms. The Sicilians not only repulsed the attacks of the combined French and Papal forces but also captured the Angevin heir, Charles of Salerno. On 6 January, 1285, Charles of Anjou died, leaving his captive son Charles of Salerno as his natural successor. Honorius IV, more peaceably inclined than Martin IV, did not renounce the Church's support of the House of Anjou, nor did he set aside the severe ecclesiastical punishments imposed upon Sicily.
On the other hand, he did not approve of the tyrannical government to which the Sicilians had been subject under Charles of Anjou. This is evident from his wise legislation as embodied in his constitution of 17 September, 1285 (Constitutio super ordinatione regni Siciliae) in which he stated that no government can prosper which is not founded on justice and peace, and passed forty-five ordinances intended chiefly to protect the people of Sicily against their king and his officials.
The death of Peter III on November 11, 1285 changed the Sicilian situation in that his kingdoms were divided between his two sons Alfonso III of Aragon (1285–91) receiving the crown of Aragon and James II (1285–96) succeeding as King of Sicily. Honorius IV acknowledged neither the one nor the other: on 11 April, 1286, he solemnly excommunicated King James II of Sicily and the bishops who had taken part in his coronation at Palermo on February 2. Neither the King nor the bishops concerned themselves about the excommunication. The King even sent a hostile fleet to the Roman coast and destroyed the city of Astura by fire.
Charles of Salerno, the Angevin pretender, who was still held captive by the Sicilians, finally grew tired of his long captivity and signed a contract on February 27, 1287, in which he renounced his claims to the Kingdom of Sicily in favour of James II of Aragon and his heirs. Honorius IV, however, declared the contract invalid and forbade all similar agreements for the future.
While Honorius IV was inexorable in the stand he had taken towards Sicily, his relations towards Alfonso III of Aragon became less hostile. Through the efforts of King Edward I of England (1272–1307), negotiations for peace were begun by Honorius IV and King Alfonso III. The Pope, however, did not live long enough to complete these negotiations, which finally resulted in a peaceful settlement of the Aragonese as well as the Sicilian question in 1302 under Pope Boniface VIII (1294–1303).
The Romans were greatly elated at the election of Honorius IV, for he was a citizen of Rome and a brother of Pandulf, a senator of Rome. The continuous disturbances in Rome during the pontificate of Martin IV had not allowed that pope to reside in Rome, but now the Romans cordially invited Honorius IV to make Rome his permanent residence. During the first few months of his pontificate he lived in the Vatican, but in the autumn of 1285 he removed to the magnificent palace which he had just erected on the Aventine.
The two largest religious orders received many new privileges from Honorius IV, documented in his Regesta. He often appointed them to special missions and to bishoprics, and gave them exclusive charge of the Inquisition.
He also approved the privileges of the Carmelites and the Augustinian hermits and permitted the former to exchange their striped habit for a white one. He was especially devoted to the order founded by William X of Aquitaine (d. 1156), and added numerous privileges to those which they had already received from Alexander IV and Urban IV. Besides turning over to them some deserted Benedictine monasteries, he presented them with the monastery of St. Paul at Albano, which he himself had founded and richly endowed when he was still cardinal.
Salimbene, the chronicler of Parma, asserted that Honorius IV was a foe to the religious orders. This may reflect the fact that he opposed the Apostolic Brethren, an order embracing evangelical poverty that had been started by Gerard Segarelli at Parma in 1260. On 11 March, 1286, he issued a bull condemning them as heretics.
At the University of Paris he advocated the establishment of chairs for Eastern languages in order to give an opportunity of studying these languages to those who intended to labour for the conversion of the Muslims and the reunion of the schismatic churches in the East.
The tomb of Pope Honorius IV is in the church of Santa Maria in Aracoeli, Rome.
Honorius IV was hardly capable of acting on this invasion and could not muster the military support necessary to achieve this plan.
