The Battle of Calven (Romansh: Chalavaina)1 took place on 22 May 1499 at the exit of the Val Müstair in the Grisons (now part of Switzerland) to the Vinschgau in County of Tyrol (now part of Italy) between the forces of King Maximilian I of the House of Habsburg and those of the free federation of the Three Leagues of the Grisons. It was the decisive battle in the southern Grisons of the Swabian War; after the defeat of the Habsburg troops, the king had to abandon his attempts to control the Engadin and the Val Müstair. The focus of operations in the Swabian War subsequently shifted again to the northern border of the Old Swiss Confederacy.
