The dukes' role in the reformation process was ambitious. Bogislaw X, despite his sympathies, forbade Protestant preaching and tumults shortly before his death. Of his sons, Georg I opposed, and Barnim IX supported Protestantism as did Georg's son, Phillip I. In 1531, Georg died, and a Landtag in Stettin formally allowed Protestant preaching, if no tumults would arise from this. On December 13, 1534, a Landtag was assembled in Treptow an der Rega, where the dukes and the nobility against the vote of Cammin bishop Erasmus von Manteuffel officially introduced Protestantism to Pomerania. Bugenhagen in the following month drafted the new Lutheran church order.Du Moulin Eckart (1976), pp.111,112
