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 that they acted upon 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 Danzig (Gdańsk) in 1308. Because Władysław was unable to come to the defense of Danzig, the Teutonic Knights, then led by Hochmeister Siegfried von Feuchtwangen, were called to expel the Brandenburgers.
