Hugues de Revel was Châtelain of the
Krak des Chevaliers from 1243 to 1248 and Grand Commander of the Order from 1251 to 1258. In the latter position, he succeeded
Jean de Ronay. Upon the death of Guillaume de Chateauneuf in 1258, Hugues de Revel was elected Grand Master of the Order. His first act was dated 9 October 1258. As soon as he was elected, he had to face the consequences of the
War of Saint Sabas.
Bohemond VI of Antioch, wanting to take revenge on the
Embriaco lords of
Gibelet, attacked them and found his allies, the Templars and his opponents William II of Botron and the Hospitallers. The death of Bertrand Embriaco, son of Hugues de Gibelet, put an end to the conflict but the Templars with the brothers of Saint-Lazare and Saint-Thomas attacked the Hospitallers, but this ended in a resounding victory of the Hospitallers and the almost complete massacre of the Templars. The Templars and the Hospitallers were able to overcome their differences in 1262, mainly with the extinction of the claims of Margat and Sidon. Revel strengthened the Hospitaller domain by acquiring the Benedictine abbey on Mount Tabor, but the consent of the Archbishop of Nazareth was not obtained until 1263. He had direct relations with the Mamluk Sultan
Baibars in 1263, 1266 and 1267–1268. The siege of the Templar fortress of Safied by the Mamluk army led the Hospitallers to negotiate a separate truce for the
Krak des Chevaliers and the fortress of
Margat in 1267, but Baybars' armies seized the Krak in 1271, which did not prevent Revel from negotiating a truce the same year. Hugues de Revel attached his name to the modification of the statutes of the Order during the general chapters of 1268, 1270, 1274 and 1276 as the compilations of sentences, the "esgarts", and customs, the "usances", fixed between 1239 and 1271 were most certainly made at the instigation of Revel. The success of the administrative activity of Revel is largely due to the treasurer Joseph de Chauncy who officiated from 1248 to 1271 before being called by
Edward I of England. Hugues de Revel died between the second half of 1277 and the first half of 1278. His successor
Nicolas Lorgne exercised his magisterium on 16 June 1278. ==Epigraphy from de Revel's magistracy==
