The Italian front was one of the main theatres of war of World War I. It involved a series of military engagements along the border between the Kingdom of Italy and Austria-Hungary from 1915 to 1918. Following secret promises made by the Allies in the 1915 Treaty of London, the Kingdom of Italy entered the war on the Allied side, aiming to annex the Austrian Littoral, northern Dalmatia and the territories of present-day Trentino and South Tyrol. The front soon bogged down into trench warfare, similar to that on the Western Front, but at high altitudes and with extremely cold winters. Fighting along the front displaced much of the local population, and several thousand civilians died from malnutrition and illness in Italian and Austro-Hungarian refugee camps.
The Battle of Vittorio Veneto was fought from 24 October to 3 November 1918 near Vittorio Veneto on the Italian Front during World War I. After having thoroughly defeated Austro-Hungarian troops during the defensive Battle of the Piave River, the Italian army launched a great counter-offensive: the Italian victory marked the end of the war on the Italian Front, secured the dissolution of the Austro-Hungarian Empire and contributed to the end of the First World War just one week later. The battle led to the capture of over 5,000 artillery pieces and over 350,000 Austro-Hungarian troops, including 120,000 Germans, 83,000 Czechs and Slovaks, 60,000 South Slavs, 40,000 Poles, several tens of thousands of Romanians and Ukrainians, and 7,000 Austro-Hungarian loyalist Italians and Friulians.

The Battle of Doberdò took place in August 1916, fought by the Kingdom of Italy and Austria-Hungary. The Austro-Hungarian army was primarily made up of regiments filled with Hungarians and Slovenians. The battle was a part of the Sixth Battle of the Isonzo, and occurred in a strategic area: the most western edge of the Karst Plateau. The Italians had already conquered the lowland area surrounding Monfalcone and Ronchi, and attempted to push over the Karst Plateau to seize control of the major road that linked the city of Trieste, with its important port, to Gorizia. After fierce combat, and sustaining heavy casualties, the Italian forces secured victory, forcing the Austro-Hungarian forces to retreat, and capturing Gorizia.
Although a member of the Triple Alliance, Italy did not join the Central Powers – Germany and Austria-Hungary – when the war started with Austria-Hungary's declaration of war on Serbia on 28 July 1914. In fact, the two Central Powers had taken the offensive while the Triple Alliance was supposed to be a defensive alliance. Moreover the Triple Alliance recognized that both Italy and Austria-Hungary were interested in the Balkans and required both to consult each other before changing the status quo and to provide compensation for whatever advantage in that area: Austria-Hungary did consult Germany but not Italy before issuing the ultimatum to Serbia, and refused any compensation before the end of the war.
The Fifth Battle of the Isonzo was fought from March 9–15, 1916 between the armies of the Kingdom of Italy and those of Austria-Hungary. The Italians had decided to launch another offensive on the Soča (Isonzo) River.
