Coloman supported Béla's attempts to revise their father's grants already during Andrew II's lifetime. The two brothers jointly confirmed a grant made by a previous ban of Croatia in 1231. Coloman ignored the privileges of the Knights Templar and wanted to collect taxes on their estates. The pope appointed Bartholomew le Gros, the bishop of Pécs, to arbitrate in the dispute together with the abbot of Pécsvárad Abbey and the provost of Pécs Chapter, but also forbade them to excommunicate Coloman without his special authorization. The three prelates persuaded Coloman to confirm the knights' privileges on 31 July 1231, but a full reconciliation was reached only after lengthy negotiations in 1239.
