The paper analyses six folk tales on the legendary pirate Klaus Störtebeker. The topic, known from the middle ages, was written down in the 19th century. Five of the works of reference come from the turn of the 20th century, as the Klaus Störtebeker story reached the peak of its popularity. The sixth comes from the first voluminous anthology of the Pomeranian folk tales. Klaus Störtebeker is connected with Hamburg and the North Sea at mouth of the Elbe River the most often. However, in different versions of its tale there are many elements with reference to Western Pomerania that can be found. As they are shaped differently, the paper compares and analyses them.
