Swietopelk I, Duke of Pomerania

Swietopelk I (Polish: Świętopełk, also referred to as Swantopolk I), (born around 1080, died before 1148) sometimes called "Swietopelk of Nakło" (Polish: Świętopełk Nakielski) to distinguish him from other rulers of the same name, was one of the first known Dukes of Pomerania; in the years 1109/13 to 1121 he ruled over Pomerelia. He is usually thought to have been the son of Świętobór I (Swantibor), although other historians make him a brother of Świętobór (as well as of a third Pomeranian duke, Dumar) and son of Siemomysl I.
