The White War (Italian: Guerra Bianca, German: Gebirgskrieg, Hungarian: Fehér Háború) is the name given to the fighting in the high-altitude Alpine sector of the Italian front during the First World War, principally in the Dolomites, the Ortles-Cevedale Alps and the Adamello-Presanella Alps.

More than two-thirds of this conflict zone lies at an altitude above 2,000m, rising to 3905m at Mount Ortler. In 1917 New York World correspondent E. Alexander Powell wrote: “On no front, not on the sun-scorched plains of Mesopotamia, nor in the frozen Mazurian marshes, nor in the blood-soaked mud of Flanders, does the fighting man lead so arduous an existence as up here on the roof of the world.

To day the area is laying grund to the ongoing fight between tourists and nature.
