Walter of Montbéliard (died in 1212) (Gauthier I de Montfaucon) was regent of the Kingdom of Cyprus from 1205 to 1210, and Constable of Jerusalem from around 1204 to his death.
Aimery, King of Cyprus and Jerusalem, gave his eldest daughter, Burgundia, in marriage to Walter and also made him constable of Jerusalem.[3][4] Aimery died on 1 April 1205 and was succeeded in Cyprus by his ten-year-old son, Hugh I.[5] The High Court elected Walter both guardian of the minor king and regent, violating the custom that prescribed that the two offices were to be separated.[4][6]
The Seljuks laid siege to Satalia (now Antalya in Turkey), an important port in Asia Minor, in 1207.[7] Satalia was held by an Italian adventurer, Aldobrandino.[7] On Aldobrandino's demand, Walter intervened in the conflict and forced the Seljuks to lift the siege.[7] However, the Greek citizens turned against him and expelled the Cypriot troops from the town with Seljuk assistance.[7]
Hugh I reached the age of majority in 1210.[4] Walter surrendered his regency, but refused to render an account of his administration of the royal treasury.[4][8] Instead, he and his family left Cyprus and settled in the Kingdom of Jerusalem.[4] Before long, Walter accused Hugh I of confiscating his estates in Cyprus and expelling him from the island without a fair judgement.[8] In his letter to Pope Innocent III, Walter also referred to an uncanonical election of a bishop in Cyprus, which brought Hugh I into a conflict with the Holy See.[9]
