Which 1918 armistice ended fighting between Italy and Austria-Hungary?

The 1918 armistice that ended fighting between Italy and Austria-Hungary was the Armistice of Villa Giusti.

The agreement was signed on 3 November 1918 at Villa Giusti, outside Padua in northern Italy, after the Austro-Hungarian army collapsed during the Battle of Vittorio Veneto. It took effect 24 hours later, on 4 November, ending organized hostilities on the Italian Front.

The armistice required Austria-Hungary to stop fighting, withdraw from occupied territories, reduce its armed forces, and surrender military equipment. Italian troops quickly moved into areas including Trento, Trieste, and parts of the former Habsburg territories. The agreement was negotiated while the empire itself was disintegrating along national and political lines.

A common mix-up is the Armistice of Belgrade. Hungary signed that separate agreement after breaking away from Austria-Hungary, so Villa Giusti is the correct answer for the armistice between Italy and the Austro-Hungarian authorities. The later Armistice of Compiègne, signed on 11 November 1918, ended fighting between Germany and the Allies.
