king's young daughter marry the newly widowed emperor, Frederick II. He agreed to then lead the next crusade and to have his fleet depart from Europe by 24 June 1225. On 1 March 1224 Honorius III wrote to the patriarch of Jerusalem of the imminent departure of the imperial fleet, and to prepare for the marriage of Yolanda of Brienne (aka Isabelle II) to the emperor. Any and all impediments were to be cleared away. Patriarch Raoul, John of Brienne and Hermann von Salza met with the pope in the summer of 1224 to deal with the emperor's announcement that conditions in Sicily had so deteriorated that he could not possibly depart for the Holy Land at this time. A new date for departure was arrived at. As a new patriarch was nominated and in place by May 1225, it would seem that Raoul died in late 1224. His replacement, Gérold of Lausanne, bishop of Valence and former abbot of Cluny, was elected on 10 May 1225.
