In late 1401, the new war against the Order overstretched the resources of the Lithuanians, who found themselves fighting on two fronts after uprisings in the eastern provinces. Another of Władysław's brothers, the malcontent Švitrigaila, chose this moment to stir up revolts behind the lines and declare himself grand duke. On 31 January 1402, he presented himself in Marienburg, where he won the backing of the Knights with concessions similar to those made by Jogaila and Vytautas during earlier leadership contests in the Grand Duchy.
