Болеслав I Храбрый
In the late 10th century, the Polish dukes Mieszko I and Bolesław I Chrobry subdued parts of Pomerania, but did not succeed to subdue the lower Oder region. In 1121/22, the Polish duke Bolesław III Wrymouth conquered the area along with the Duchy of Pomerania under Wartislaw I. The tribe was subsequently Christianized, missionary Otto of Bamberg celebrated the first mass baptism in Pyrzyce. A separate tribal identity, if upheld so far, vanished when it was integrated in the Duchy of Pomerania.
