[11] During the 12th century, the pagan Pomeranians faced continuous incursions by their expanding Christian neighbours of Denmark, Poland and the Saxon dukes of the Holy Roman Empire.

In 1121, they were eventually subdued by Polish Duke Bolesław III Wrymouth, who established a diocese with its seat at Kołobrzeg, where Reinbern became the first bishop.

[12][13] The influx of settlers from the Holy Roman Empire during the Ostsiedlung caused the Germanization of Pomerania, as many native Pomeranians were slowly and gradually assimilated and discontinued the use of their Slavic language and culture.
