The
Truce of Ulm (also known as the
Treaty of Ulm) was signed in
Ulm on March 14, 1647 between
France,
Sweden, and
Bavaria. This
truce was developed after France and Sweden invaded Bavaria during the
Thirty Years' War. Both invading nations forced
Maximilian I, Elector of Bavaria, to conclude the truce and renounce his alliance with Emperor
Ferdinand III. However, Maximilian broke the truce and returned to his alliance with Ferdinand in the autumn of 1647.
