In the aftermath of the defeat at Grunwald, the Teutonic Order lost much of its military and economic importance. The way of thinking of the Old Prussians had changed as well. It was not surprising that when Grand Master Heinrich von Plauen was heading towards war with the Kingdom of Poland, his army (consisting of Prussian nobility and villagers) stationed near the village of Lautenburg (Lidzbark Welski) refused to fight the Poles on 29 September 1413, and he was relieved from his position as Grand Master by Küchmeister.
