Editing Pope Honorius IV (section)

=== Sicilian Conflict ===
{{Main|War of the Sicilian Vespers}}
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. Martin IV put Sicily and Peter III under an [[interdict]], deprived Peter III of the [[Crown of Aragon]], and gave it to [[Charles of Valois]], the younger of the sons of King [[Philip III of France]], 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 [[Capetian House of Anjou|Angevin]] heir, [[Charles II of Naples|Charles of Salerno]]. On 6 January 1285, Charles of Anjou died, leaving his captive son Charles 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.

Honorius did not approve of the tyrannical government the Sicilians had been subject to under Charles of Anjou. This is evident from legislation embodied in his constitution of 17 September 1285 (''Constitutio super ordinatione regni Siciliae''), in which he stated that no government can prosper that is not founded on justice and peace. 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 [[List of Aragonese monarchs|crown of Aragon]], and [[James II of Aragon]], who succeeded as King of Sicily. Honorius IV acknowledged neither the one nor the other: on 11 April 1286, he solemnly [[excommunication|excommunicated]] King James II of Sicily and the bishops who had taken part in his coronation at [[Palermo]] on 2 February. 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 [[Torre Astura|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 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. 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]].
