During his pontificate he largely continued to pursue the pro-French political policy of his predecessor, Pope Martin IV. Giacomo Savelli was born in Rome into the rich and influential family of the Savelli. His father was Luca Savelli, who died as Senator of Rome in 1266. His mother Joanna belonged to the Aldobrandeschi family. In 1261 he was created Cardinal Deacon of Santa Maria in Cosmedin by Pope Urban IV, who also appointed him papal prefect in Tuscany and captain of the papal army. Savelli became Protodeacon of the Sacred College in November 1277 and as such, he crowned Popes Nicholas III on 26 December 1277 and Martin IV on 23 March 1281. When Martin IV died on 28 March 1285, at Perugia, Cardinal Savelli was unanimously elected Pope on 2 April, on the first ballot, and took the name of Honorius IV.
He remained at Perugia throughout April, but, once negotiations were completed, he travelled to Rome and took up residence in the family palace next to Santa Sabina on the Aventine Hill. Sicilian affairs required immediate attention from the new Pope. Previously, under Martin IV, the Sicilians had rejected the rule of Charles of Anjou, taking Peter III of Aragon 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. On the other hand, he did not approve of the tyrannical government the Sicilians had been subject to under Charles of Anjou.
He passed forty-five ordinances intended chiefly to protect the people of Sicily against their king and his officials. The death of Peter III on 11 November 1285 changed the Sicilian situation in that his kingdoms were divided between his two oldest sons: Alfonso III of Aragon, who received the crown of Aragon, and James II of Aragon, who succeeded as King of Sicily. 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 27 February 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, negotiations for peace were begun by Honorius IV and King Alfonso III. Rome and the States of the Church enjoyed a period of tranquillity during the pontificate of Honorius IV, the like of which they had not enjoyed for many years. He had the satisfaction of reducing the most powerful and obstinate enemy of papal authority, Count Guido of Montefeltro, who for many years had successfully resisted the papal troops. 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 live in Rome, but now the Romans cordially invited Honorius IV to make Rome his permanent residence. In his relations with the Holy Roman Empire, where no more danger was to be apprehended since the fall of the Hohenstaufen dynasty, Martin followed the moderate course taken by Gregory X. Rudolf I of Germany sent Bishop Henry of Basel to Rome to request coronation. 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.
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. At the University of Paris he advocated the establishment of chairs for Eastern languages to teach these languages to those who would labour for the conversion of the Muslims and the reunion of the schismatic churches in the East. He raised only one man to be cardinal, his cousin Giovanni Boccamazza, archbishop of Monreale, on 22 December 1285. The tomb of Pope Honorius IV is in the church of Santa Maria in Aracoeli in Rome. The Mongol ruler Arghun sent an embassy and a letter to Pope Honorius IV in 1285, a Latin translation of which is preserved in the Vatican. We will send our messengers to ask you to send an army to Egypt, so that us on one side, and you on the other, we can, with good warriors, take it over.
