The dissatisfaction of the Bavarian Elector Maximilian I with the imperial warfare, political and other reasons caused the discord in Bavarian-imperial relations. The result was the Bavarian conclusion of the separate armistice from Ulm with enemies on 14 March 1647.
After twenty-eight years, Maximilian seceded from the Emperor. In September, however, he revoked a mentioned treaty and started a new military cooperationwith him.
