Odo of Montbéliard was a leading baron of the crusader Kingdom of Jerusalem in the early 13th century. He often held the highest offices in the kingdom including bailli and constable. Odo was the son of Walter of Montbéliard who was a regent of the kingdoms of Jerusalem and Cyprus. Odo's wife Eschiva of Saint Omer, daughter of Raoul of Saint Omer, was the heiress of the Principality of Galilee. In 1220 Odo was appointed constable of the Kingdom of Jerusalem by the kingJohn of Brienne. In 1223 Odo was appointed as bailli of the kingdom. However in 1227 the Holy Roman Emperor and king of JerusalemFrederick II sent out Thomas of Aquino to replace Odo. The following year Odo was appointed as one of the three commanders of Frederick's Crusade along with Richard Filangieri and Hermann von Salza. At the end of the Sixth Crusade, just before Frederick left Acre to return to Europe, he appointed Odo as constable. Then while Frederick was on his way to the harbour he was pelted with dung and entrails by the unappreciative people of Acre. Odo and John of Ibelin quelled the unrest. In 1233 Odo was caught up in the disaffection at Frederick's decision to appoint Philip of Maugastel as bailli; an appointment which Odo was prepared to support. A furious mob attacked supporters of Philip and it was only the intervention of John of Caesarea that saved Odo from being killed. Odo and Balian of Sidon shared the role of bailli in 1236 against the wishes of Pope Gregory IX whose choice of Richard Filangieri was unacceptable to the barons. Odo took part in Theobald I of Navarre's Crusade of 1239-1240 but there were tensions between Theobald and local barons including Odo. However, the treaty between Theobald and the sultan of Damascus in 1240 gave Galilee back to the Kingdom of Jerusalem, and as Odo of Montbéliard was titularPrince of Galilee, he now took up the rule of Galilee. Tiberias, the capital of Galilee, was sacked by the Khwarezmians in 1244, after which Odo began rebuilding the citadel. But in 1247 the city of Tiberias and Odo's Principality of Galilee were lost to the armies of the Ayyubid sultan al-Salih Ayyub. Odo died later that year.
