^Loew PO: Danzig. Biographie einer Stadt, Munich 2011, p. 32: "Sambor [...] styled himself 'princeps Pomoranorum,' [...], but not 'dux,' which was the privilege of the Piasts." p. 33: "After Sambor's death [...] his brother Mestwin [...] strove after gaining ever greater independence from Poland. He confidently styled himself 'princeps in Danzk' and expanded southwards. His oldest son Swantopolk (Swietopelk), ruling from 1217 onwards, exploited Poland's fragmentation to acquire independence for his realm; already since 1227 he styled himself 'dux,' 'Duke of Pomerelia.'"
