On May 23, 1915, Italy declared war on Austria-Hungary, entering World War I on the side of the Allies. This declaration opened up a new front in World War I, stretching 600 kilometers along Italy's border with Austria-Hungary. Italy's decision to join the war was influenced by the secret Treaty of London, signed with Britain, France, and Russia in April 1915, which promised Italy substantial territorial gains at the expense of Austria-Hungary, including control of Italian-populated regions and expansion of its empire in the Balkans. Prior to the war, Italy had been a partner in the Triple Alliance with Germany and Austria-Hungary but had declared its neutrality when the war broke out in 1914, citing that the treaty did not oblige it to provide military assistance. However, by 1915, Italy's position had shifted, and it entered the war against its former ally, Austria-Hungary, leading to a series of military engagements along their shared border.

Italy's declaration of war on Austria-Hungary
On May 23, 1915, Italy declared war on Austria-Hungary, entering World War I on the side of the Allies: Britain, France, and Russia. This declaration of war, sometimes referred to as 'l'intervento', aroused outrage and acrimony, as Italy had been a member of the Triple Alliance with Austria-Hungary and Germany since 1882.
Italy's decision to join the Allies was largely based on the assurances it received in the Treaty of London, signed in April 1915. The Treaty promised Italy a range of territorial gains, including control over territory on its border with Austria-Hungary, stretching from Trentino through the South Tyrol to Trieste. Italy was also promised parts of Dalmatia, numerous islands along Austria-Hungary's Adriatic coast, the Albanian port city of Vlore, and territory from the Ottoman Empire. In addition, the Allies provided concrete financial assistance in the form of a £50 million loan.
Upon declaring war, the Italian army advanced into the South Tyrol region and to the Isonzo River, where they were met by stiff defense from Austro-Hungarian troops. The Italian forces, despite their numerical advantage, struggled due to equipment and munition shortages, as well as poor morale and a lack of confidence in their newly appointed commander, General Luigi Cadorna. The Italian front, which involved a series of military engagements along the border between the two countries, soon bogged down into trench warfare at high altitudes, with extremely cold winters.
The Italian declaration of war opened up a new front in World War I, stretching 600 kilometers along Italy's border with Austria-Hungary. Italy, which had only recently become a unified nation in 1859, was not yet fully industrialized or prepared for large-scale warfare. Despite mobilizing 1.2 million men in the spring of 1915, they possessed equipment for only 732,000. The war resulted in significant casualties on both sides, with Italian military deaths totaling over 531,000 by the time the Armistice with Austria was signed on November 4, 1918.

The Treaty of London
On April 26, 1915, Italy signed the Treaty of London, committing itself to enter World War I on the side of the Allies. The treaty was a secret agreement between the United Kingdom, France, and Russia on one side, and Italy on the other. Italy was promised significant territorial gains against Austria-Hungary, the Ottoman Empire, and in Africa, where it was promised an enlargement of its colonies.
The terms of the treaty included a belt of territory in the north, stretching from Trentino through the South Tyrol to Trieste, which would become Italian. Additionally, they were promised Balkan gains, including parts of Dalmatia, numerous islands along Austria-Hungary's Adriatic coast, and the Albanian port city of Vlore (known in Italian as Valona). They were also promised a protectorate over a vast swathe of Albania and the prospect of further territory from the Ottoman Empire.
The Entente countries hoped that by enticing Italy to join their side, they could force the Central Powers, particularly Germany and Austria-Hungary, to divert some of their forces away from existing battlefields. They also hoped that Romania and Bulgaria would be encouraged to join them after Italy did the same.
On May 23, 1915, Italy declared war on Austria-Hungary, but it waited a year before declaring war on Germany, leading to resentment from France and the UK. Italy's entry into the war did not entice Bulgaria to join the Entente, as they became more cautious due to early British and French setbacks at Gallipoli.

Italy's territorial gains
On 23 May 1915, Italy declared war on its former ally, Austria-Hungary, joining World War I on the side of the Entente. This move, sometimes referred to as 'l'intervento', was motivated by the promise of significant territorial gains for Italy, as outlined in the Treaty of London signed in April 1915.
The Treaty of London offered Italy a range of territorial incentives to join the Entente, including a continuous stretch of land in the north, from Trentino through the South Tyrol to Trieste. This northern territory was particularly enticing as it provided access to the Adriatic coast. Additionally, Italy was promised gains in the Balkans, specifically in Dalmatia and numerous islands along the Austrian Adriatic coast, including the Albanian port city of Vlore (known as Valona in Italian). These Balkan acquisitions evoked the historical glories of Rome and Venice, appealing to Italian nationalism. Furthermore, Italy was offered control of a vast swathe of Albania and the potential for further expansion into the Ottoman Empire.
Italy's decision to join the Entente powers during World War I was influenced by the allure of territorial expansion. The promise of these gains outweighed Italy's previous allegiance to the Triple Alliance with Austria-Hungary and the German Empire. The territorial incentives offered by the Entente powers, including control of strategic coastal areas and the prospect of an Italian Empire in the Balkans, ultimately guided Italy's foreign policy choices during this critical period.
The Italo-Austrian conflict, known as the Italian Front, witnessed a series of intense military engagements along their shared border. The Italian forces initially faced challenges due to inadequate equipment and the difficult terrain of the Alpine regions. Despite these setbacks, Italy emerged victorious in 1918, capturing Trento and Trieste and successfully annexing the territories outlined in the Treaty of London.

Austria-Hungary's refusal to compromise
On May 23, 1915, Italy declared war on Austria-Hungary, entering World War I on the side of the Allies, despite having been a member of the Triple Alliance alongside Germany and Austria-Hungary since 1882. This was a direct result of Austria-Hungary's refusal to compromise on Italy's territorial ambitions.
Secondly, Italy and Austria-Hungary had competing irredentist claims over Alpine and Adriatic territories. Italy sought to annex regions such as Trentino, South Tyrol, Trieste, and parts of Dalmatia, which bordered Austria-Hungary. These territories were considered crucial for Italy's national dream of establishing a unified Italian state. However, Austria-Hungary was unwilling to cede control over these areas, as they were strategically important and held valuable coastal access.
Additionally, Italy's ambitions extended beyond Europe, with desires for an Italian Empire that included territories in the Balkans and the Ottoman Empire. These ambitions were encouraged and supported by the Allies, who promised Italy significant territorial gains if they joined their side. The Treaty of London, signed in April 1915, guaranteed Italy a range of territorial acquisitions, including control over northern territories bordering Austria-Hungary and gains in the Balkans, such as parts of Dalmatia and the Albanian port city of Vlore. The prospect of fulfilling their imperial ambitions and gaining a foothold in the Mediterranean Basin was a strong motivator for Italy to side with the Allies.
Moreover, Italy's position within the Triple Alliance was ambiguous and tenuous. While Germany and Austria-Hungary shared a strong military alliance, Italy's relationship with them was less solid. Italy had always been the shakiest member of the European alliance system, and its interests were not always aligned with those of its nominal allies. The outbreak of World War I highlighted these differences, as Italy chose to remain neutral initially, while Germany and Austria-Hungary became firmly entrenched in the conflict. Italy's neutrality allowed it to be courted by both sides, and it carefully considered its options to maximize its gains.
In summary, Austria-Hungary's refusal to compromise with Italy on territorial issues, coupled with Italy's ambitions for expansion and its uncertain alliance status, led to Italy's declaration of war on May 23, 1915. This marked a significant shift in the European alliance system and opened up a new front in World War I along the mountainous border between Italy and Austria-Hungary.

Italy's neutral stance
When World War I began in July 1914, Italy was a partner in the Triple Alliance with Germany and Austria-Hungary. However, Italy decided to remain neutral and issued a Declaration of Neutrality on 2 August 1914. Italy's neutral stance was influenced by various factors, including the desire for territorial gains and the competing interests within the country.
Firstly, Italy sought to annex territory along the border with Austria-Hungary, stretching from the Trentino region in the Alps to Trieste on the Adriatic Sea. This would "liberate" Italian-speaking populations from the Austro-Hungarian Empire and unite them with their cultural homeland. Italy's ambition for territorial expansion was a significant factor in its neutrality, as it sought to negotiate with both sides to secure the most favourable terms.
Secondly, Italy's neutral stance reflected the divided sentiments within the country. While nationalists generally favoured entering the war, they were split between aligning with Germany or Britain. Liberals and Socialists, on the other hand, largely supported remaining neutral. The Freemasons, who held influence in Italy at the time, lobbied for Italy to join the war on the side of Great Britain and France. These competing interests created a challenging situation for the Italian Parliament, which struggled to navigate the complex domestic dynamics.
On 23 May 1915, Italy abandoned its neutral position and declared war on Austria-Hungary, joining the Entente powers. This decision was driven by the promises made in the Treaty of London, signed in April 1915, which guaranteed Italy significant territorial gains if it entered the war on the Entente side.
