The Austro-Hungarian Empire signed an armistice with Italy on this day in 1918. Signing an armistice with its former ally, Austria-Hungary was forced to surrender to the allies, with unconditional surrender coming only eight days later. Although the United States had previously allowed for a Austro-Hungarian confederation to take the place of the Empire, by 1918 it had gone back on its word, demanding the dissolution of the Empire and supporting the rapidly growing Czechoslovakian and Slavic independence movements. The Slavs in the South had already assembled into a Yugoslav Committee, determined to form a united Slavic country. Meanwhile, a provisional Czechoslovakian government joined the Allies in October of 1918. By November of 1918, the Austro-Hungarian Empire had no choice but to accepts the Allied demands, dissolving the empire and ending the Hapsburg reign over Austria. Along with granting independence to many parts of the empire, the armistice also granted Italy its neighboring provinces, long claimed by the country to be part of its cultural union.
