Cardinal Cholet was commissioned by his long-time friend,
Pope Martin IV, to preach the
Aragonese Crusade in 1283. The date on his commission as Legate in France is 9 April 1283. On 27 August 1283, he was granted the faculty of transferring the "vacant" throne of Aragon and the County of Barcelona to one of the sons of King Philip of France. On 3 September 1283, Pope Martin ordered all of the ecclesiastical persons in France to give 10% of their income for three years to the King of France for the Crusade against Pedro of Aragon. He ordered Cardinal Cholet to see to it that these contributions were paid, even by the monastic orders, Templars and Hospitallers. On 10 January 1284, the Pope prodded him to get on with the business: Prince Charles was finally chosen, after long negotiations with Cardinal Cholet, and Pope Martin IV confirmed his appointment as King of Aragon and Count of Barcelona on 5 May 1284. On 4 June 1284, Cardinal
Bernard de Languissel, Bishop of Porto, was ordered to preach the crusade against former King Pedro of Aragon throughout his legation in northern Italy, and Cardinal
Gerardo Bianchi, Bishop of Sabina, to do the same in south Italy. The Pope even enlisted the Dominicans and Franciscans in Sardinia and Corsica to preach the crusade. Cardinal Jean Cholet was also given
legatine authority over the orders of
friars, both generally at his appointment as Legate in the Kingdom of France, and as part of his commission to preach the
plenary indulgence to all those who fought alongside
Charles of Valois for the
Crown of Aragon against
Peter III. By 5 May 1284, Cardinal Cholet had accumulated the following 'provinces' in his Legatine commission: France, Navarre, Aragon, Valencia, the
Kingdom of Majorca, Lyon, Besançon, Vienne, Tarentaise, Ebrudun, Liège, Metz, Verdun, and Tulle. In mid-August, 1284, the Cardinal presided over a Council meeting in Paris; a
maxima multitude praelatorum attended. In 1284, when the aldermen of
Lille attacked a troupe of
Dominicans trying to preach the Aragonese Crusade in their town, Cholet fined them 4,000
livres de Paris and used the money to finance the crusade. In 1285, Cholet himself accompanied Charles into Aragon. The chronicle of S. Paul de Narbonne informs us that on 15 March 1285, the Cardinal accompanied King Philip the Hardi and his two sons, Philip and Charles, in their entry into Narbonne. From there they proceeded into Roussilon and entered Catalonia. On 28 April 1285 at
Girona, Cholet placed his
galero on Charles' head and pronounced him king. This act earned Charles the satirical nickname
roi du chapeau or
Cárles, rey del Xapeu ('king of the hat'), implying that he was no properly crowned king, merely a creature of the Papacy. It was at that moment that Cardinal Cholet made the famous remark, If any man die there, which may God forbid, then will he in shining whiteness ascend into the presence of God, for God will not in any wise permit that his soul be sent to purgatory. The Pope's grant of a plenary indulgence was being applied. Charles' elevation was approved by the Pope on 5 May 1284. But, in an ironic twist, Charles' father, Philip III, died of dysentery in Perpignan, the capital of his ally
James II of Majorca, on 5 October 1285. His skin was removed and interred in the Cathedral of Narbonne. His body was carried back to Paris by the many members of the French Court who had accompanied him in the Crusade against Aragon. When the cortege reached Paris, the
Dominicans, who had been highly favored by the late King, wished to have a share of the relics. They employed the Confessor of the new king,
Philip IV, to persuade the king to give them Philip III's heart—which he most imprudently agreed to do. There was an immediate protest at this violation of custom and ceremonial. The Benedictine monks of
Saint Denis ought to have received all the remains. Both heart and bones were separately buried in the Basilica. Cardinal Cholet and the principal lords of the French Court supported the monks of S. Denis, and some members of the University of Paris even put in their opinion, that the King should not have given the heart, the monks of S. Denis should not have surrendered it, and the Dominican friars should not have kept it, without a specific dispensation from the Pope. No one was pleased, but the Dominicans had and kept possession. Elsewhere, the late King's uncle, Charles of Anjou, King of Sicily, also died in 1285, on 7 January, and King Pedro III of Aragon died on 11 November 1285, one month after his great antagonist, Philip III. On 6 January 1286, the Cardinal Legate was present at the Coronation of Philip IV. In accordance with a bull of Honorius IV, he settled the differences between the scholars of the University and the Chancellor of Paris. In 1286 he gave the Royal Abbey of S. Lucien de Beauvais funds to purchase the land and seigneurie of Foulangues. At some point he also funded the acquisition of the fief of Maulers. But Cardinal Cholet was still preaching the pope's crusades against his secular opponents in 1286. Pedro III may have died, but Sicily was still not back in papal hands. A legitimate king was needed to swear
fealty to the Papacy. On 30 April 1286,
Pope Honorius IV granted an indulgence to all Italian clergy who paid in one year the tithe which had been levied for three years. In May he ordered Cholet to use the indulgence sparingly. ==Conclave: absent==
