The capture of Danzig marked a new phase in the history of the Teutonic Knights. The persecution and abolition of the powerful Knights Templar, which began in 1307, worried the Teutonic Knights, but control of Pomerelia allowed them to move their headquarters in 1309 from Venice to Marienburg (Malbork) on the Nogat River, outside the reach of secular powers. The position of Prussian Landmeister was merged with that of the Grand Master. The Pope began investigating misconduct by the knights, but no charges were found to have substance. Along with the campaigns against the Lithuanians, the knights faced a vengeful Poland and legal threats from the Papacy.
