Otto arrived in Pyritz, and the fact that he was already wealthy assured the Pomeranians that his aim was only to convert them to Christianity, not to become wealthy at the expense of the Pomeranian people. He persuaded the Pomeranians that their conversion would protect them from further punishment by his God, which was how the devastating Polish conquest was depicted. This approach turned out to be successful, and was backed by parts of the Pomeranian nobility who had already been raised as Christians, like Duke
