The Italian Front was a major theater of conflict during World War I, primarily fought between the Kingdom of Italy and the Austro-Hungarian Empire. It began in 1915 and lasted until the war's end in 1918, characterized by a series of battles along the Isonzo River and in the Alps. The front was marked by difficult terrain and trench warfare, leading to high casualties and limited territorial gains. Key battles on the Italian Front included the Battle of Caporetto in 1917, where Italian forces suffered a significant defeat, and the Battle of Vittorio Veneto in 1918, which resulted in a decisive victory for Italy. The front ultimately contributed to the collapse of the Austro-Hungarian Empire and the reshaping of post-war Europe.
