A dispute over the succession to the Duchy of Pomerelia embroiled the Order in further conflict at the beginning of the 14th century. The Margraves of Brandenburg had claims to the duchy which they asserted after the death of King Wenceslaus of Poland in 1306. Duke Władysław I the Elbow-high of Poland also claimed the duchy, based on inheritance from Przemysław II, but he was opposed by some Pomeranians nobles. They requested help from Brandenburg, which subsequently occupied all of Pomerelia except for the citadel of Gdańsk in 1308. Because Władysław was unable to come to the defense of Gdańsk, the Teutonic Knights, then led by Grand Master Siegfried von Feuchtwangen, were called to expel the Brandenburgers.
