An Italian patriotic movement of the late 19th and early 20th centuries. Its members aimed at liberating all lands, mainly in the Alps and on the Adriatic, inhabited by Italians and still held by the Austro-Hungarian empire after 1866. Its activities were restrained when the Italian government entered into the Triple Alliance with the Austro-Hungarian empire and Germany in 1882, but the movement headed the campaign for Italy’s intervention in World War I in 1915. The Settlement of Versailles satisfied most of its claims.
