The Margraves of Brandenburg also claimed the region and had Przemysł assassinated in early 1296. Władysław I the Elbow-high (Łokietek), Przemysł's successor, was only in loose control of Pomerelia and Gdańsk with the actual control of the area being in the hands of the local Swienca family who had come into power already under Mestwin II. In 1301, one year after Wenceslaus II of Bohemia had been crowned king of Poland, the princes of Rügen, who also claimed to be the heirs of Pomerelia, mounted an expedition. Wenceslaus, who with the Polish crown had also acquired the claim to Pomerelia, called the Teutonic Order for help. The Teutonic knights occupied Gdańsk, repelled the princes of Rügen, and left the town in 1302. While the Norwegian king Haakon backed Rügen's claims, his 1302 call to the Hanseatic cities for aid remained without answer.
