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.
[1] Two years later he joined his cousin, Walter III, Count of Brienne, who had laid claim to the Principality of Taranto and other domains in the Kingdom of Sicily and invaded Southern Italy.
[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] 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.
