• Partition of the Duchy of Pomerelia
In 1227, after the death of Leszek the White, the High Duke of Poland, the Duchy of Pomerelia had achieved independence from the Kingdom of Poland. Following that, the duke of Pomerelia, Swietopelk II, had partitioned the county between himself and his brother, Warcisław I of Świecie, to whom he had given the Świecie and Lubiszewo. Wartisław I had died between 1227 and 1233. Following his death, his state was divided between Swietopelk II, who got the area of Świecie, Sambor II, who got the Duchy of Lubiszewo, and Racibor of Białogarda, who got Duchy of Białogarda.
