The duchy was formed after gaining independence from the Kingdom of Poland in the 11th century, following the death of Bolesław I the Brave in 1025. The duchy was then integrated back into Poland in 1046 or 1048 by Casimir I the Restorer, and its land remained under Polish rule until around 1060, when the duchy was restored. In 1119, the duchy was again conquered by Poland and became its fiefdom, being ruled by stewards under the rule of the King of Poland. In 1210, it briefly became a fiefdom of Denmark under the rule of Valdemar II, until it was reconquered the next year by the king of Poland, Leszek the White. In 1227, the duchy gained independence from Poland, whereupon it was divided into the Duchy of Gdańsk and the Duchy of Świecie and Lubiszewo. Pomerelia united again in 1270 from the duchies of Gdańsk and Świecie, remaining independent until 1294, when Przemysł II, king of Poland, became its duke, making it again dependent on Poland. In 1308, the city of Gdańsk was occupied by the Margraviate of Brandenburg. After this event, the whole duchy was conquered by the State of the Teutonic Order.
