King Emeric was Catholic and had himself taken the cross in 1195 or 1196. Many of the crusaders were opposed to attacking Zara, and some, including a force led by the elder Simon de Montfort, refused to participate altogether and returned home or went to the Holy Land on their own. While the Papal legate to the Crusade, Cardinal Peter of Capua, endorsed the move as necessary to prevent the crusade's complete failure, the Pope was alarmed at this development and wrote a letter to the crusading leadership threatening excommunication.
