Roger de Moulins was little known to history before his elevation to the magistracy of the Order. He may have been a Norman knight from Moulins, but there is no proof of that. His first concern, after his installation in the Holy Land, was to urge
Baldwin IV of Jerusalem and the principal lords of the kingdom to continue the war against
Saladin with vigor. On 25 November 1177, he participated in the
Battle of Montgisard, winning "the most beautiful victory of the crusades" against the
Ayyubids. Saladin's defeat is regarded as so severe that it was only redeemed by his victory ten years later at the
Battle of Hattin in 1187. The Hospitallers formed one of the strongest military organizations of the kingdom, but this was contrary to the spirit of the Order, distancing them from the works of hospitality for which it had been founded. Pope
Alexander III called them back to the observance of the rule of
Raymond du Puy between 1178 and 1180, issuing a bull that forbade them to take up arms unless they were attacked and urged them not to abandon the care of those sick and in poverty. The Hospitallers were clear rivals of the
Knights Templar. Alexander III persuaded Roger de Moulins to make a truce in 1179 with
Odo de St Amand, then
Grand Master and also a veteran of Montgisard. The pope instituted an arbitration process. Three brothers from each order were chosen as arbiters, each of whom had the right to appoint two other brothers. If the arbitration was insufficient, the friars were to call upon persons outside the orders. If there was still a disagreement, the matter would be submitted in the last resort to the two Grand Masters. The agreement with the Templars was not a good one. They were in constant conflict over their rights and possessions. On one point, the Templars and the Hospitallers were in perfect agreement. The grievances that diocesan authority harbored against the privileges of the orders. The secular clergy did not accept the immunities and privileges that the two orders held from the Holy See. In March 1179, the prelates appealed to the
Third Lateran Council, which reformed the abuses and forbade the orders to receive churches and tithes from the laity without the agreement of the diocesan authority, and cancelled the recent
moderno temporen donations. This decision, while reforming the abuses, left the privileges of the orders intact. Vexed, the clergy redoubled their attacks and it took two papal bulls, 26 August 1180 and 14 August 1182, to bring the clergy back to respecting the decisions of the council, as well as the persons and property of the Hospitallers, and prescribing the excommunication of anyone who would attack the Hospitallers and the Templars with an armed hand. In 1184, he toured Europe with
Arnold of Torroja, the Grand Master of the Templars, and
Heraclius, the
Latin Patriarch of Jerusalem. One objective was to plead with kings and pope
Lucius III to send a new crusade to strengthen the Latin states in the East, which were at the mercy of the growing power of Saladin and established the Hospitaller Order in England, France and Germany. On his way back he helped the
Kingdom of Sicily attack
Thessalonica in 1185. In his time, he established the tradition of the Grand Master of the Hospitallers involvement in the politics of the Kingdom of Jerusalem. After the death of
Baldwin V of Jerusalem in August 1186, Roger ended up at conflict with
Gerard de Ridefort, Arnold's successor as Grand Master, and with
Raynald de Châtillon due to his having opposed
Guy of Lusignan - he at first refused to hand over his key to the royal treasury when Guy was crowned King of Jerusalem in 1186. == The Battle of Cresson ==
