Guérin de Montaigu
[4] Tradition would have it that he was a native of Auvergne and that he was the brother of Pierre de Montaigu, Grand Master of the Knights Templar from 1219 to 1232.
The Knights Templar had aligned themselves with the bourgeoisie of Antioch and the alliance of az-Zahir Ghazi, the Ayyubid sultan of Aleppo, while the Hospitallers sided with Raymond-Roupen and the king of Armenia.
Leo I supported his claims by confiscating the Templars' property in Cilicia, ruining Antioch's trade by raids, and even risking excommunication in 1210–1213.
The leader of the Antiochene nobility William Farabel in 1219, allowed the return of Bohémond IV and the escape of Raymon-Roupen, who later died in 1222.
He authorized Gerald of Lausanne, Latin Patriarch of Jerusalem, to lift the ban if Bohémond agreed to make peace with the Hospitallers.
Bohémond confirmed the Hospitallers' right to hold Jabala and a nearby fortress and granted them money fiefs in both Tripoli and Antioch.
Montaigu received from Raymond-Roupen Gibelacar on 22 May 1207, the castle of Château de la Vieille in September 1210 and an annuity of 200 bezants on the casal of Gédéide in December 1216.
Wichard of Karslberg gave them his land of Engelsdorf in Carinthia in February 1214; Poppo of Wertheim gave Morbach, confirmed in 1218 by his family; they received from Ulrich of Stubenberg on July 18, 1218 the towns of Hatzendorf and Kroisbach in Styria; from Vulvin of Stubenberg, Söchau and Aspach in June 1221; from Count Hugues II of Montfort, the church of Feldkirch, a chapel in the valley of Sainte-Marie and confirmation of goods in Cluse, Brégence and Rinegg in September 1218; from Count Baudouin of Bentheim goods in Esterwege in 1223.
[4] In 1208, the duke of Burgundy Eudes III made a series of donations in memory of his stay in the Holy Land in 1190; Milon de Saint-Florentin gave them land at Villiers-Vineux on June 26, 1220; the count Henri I of Rodez the city of Canet, Frontignan, the Bastide-Pradines, Canabières and Bouloc, on October 18, 1221; the viscount of Béarn Guillaume-Raymond de Moncade the castle of Macied on February 17, 1224; Archambaud IV the house of Buys on June 1225.
[4] The first wave of troops of the Fifth Crusade, due to the efforts of pope Innocent III, arrived at Acre in the late summer of 1217.
The king of Jerusalem, John of Brienne, gathered them all together in the presence of the three grand masters of the military orders for a council of war and to determine the course of action to be taken.
During a skirmish against the sultan's camp at Fariskur on 22 August 1219, the Marshal of the Hospitaller, Aymar de Lairon, fell with thirty two of his companions.
[4] Emperor Frederick II sent four ships to Acre for John of Brienne, Raoul of Merencourt, the Latin patriarch of Jerusalem, the legate Pelagius Galvano and the grand masters of the military orders to confer with him on his promise to go on Crusade.
In 1228, he persuaded pope Gregory IX to break the truce holding between Christian and Muslim powers, but refused to serve in the army commanded by Frederick II, who was excommunicated.
