Italy’s role in the great conflicts of the 20th century was defined not only by its own ambitions but by the shifting constellation of powers it chose to stand beside. From the secret promises of the First World War to the complex calculations of the Cold War, the peninsula’s alliances have been a central thread in the fabric of modern European history. Understanding these partnerships is essential to grasping Italy’s current geopolitical posture and its enduring search for security and influence.
The Triple Alliance and the It-Turn
In the decades before the outbreak of the First World War, Italy was a proud member of the Triple Alliance, formally bound to Germany and Austria-Hungary. This defensive pact was a cornerstone of the conservative order established after the Franco-Prussian War. However, Italian leadership viewed the alliance through a lens of perceived national incompleteness, particularly with the irredentist claim over Trentino and Trieste, territories controlled by Austria-Hungary. When the war erupted in 1914, Italy declared neutrality, arguing that the alliance was defensive and did not compel action alongside an aggressor. This diplomatic pivot, formalized in the 1915 Treaty of London, saw Italy join the Entente Powers, a dramatic realignment that reshaped the map of Europe.
World War I and the Entente Bargain
Fighting alongside the British, French, and later the Americans, Italy endured a brutal war on the Isonzo front, suffering immense casualties for territory that was both strategically questionable and ethnically contested. The alliance with the Entente was a calculated gamble, driven by the promise of territorial expansion at the expense of a faltering Austria-Hungary. While the victory at Vittorio Veneto and the dismantling of the Austro-Hungarian Empire were significant achievements, the sense of betrayal lingered. Italy entered the post-war negotiations feeling it had not been fully rewarded for its sacrifices, a sentiment that fueled domestic discontent and created the conditions for the rise of fascism. The alliance had delivered the dream of Italia irredenta, but it had also sown the seeds of future disillusionment.
The Pact of Steel and the Axis Descent
In the 1930s, as fascism consolidated its power, Italy found a new partner in Adolf Hitler’s Germany. The Rome-Berlin Axis, formalized through the Pact of Steel in May 1939, was a marriage of convenience between two regimes that shared expansionist ideologies and a deep suspicion of the established liberal order. This alliance, however, was profoundly asymmetrical. Italy’s military was ill-prepared for the mechanized warfare that Germany had mastered, and its economy was not robust enough to sustain a long-term conflict. The decision to enter the Second World War on Germany’s side in June 1940 was less a strategic calculation and more a catastrophic submission to German pressure, leading to a series of devastating defeats across Africa, the Balkans, and the Mediterranean.
The Collapse and the Armistice
The alliance with Germany collapsed under the weight of military failure and internal betrayal. The Allied invasion of Sicily in July 1943 triggered a political earthquake, leading to the arrest of Mussolini by the Fascist Grand Council and the installation of a new government under Marshal Pietro Badoglio. Seeking a way out of the war, the new leadership engaged in secret negotiations with the Allies. The Armistice of Cassibile, announced on September 8, 1943, was a humiliating about-face. Italy was immediately invaded by German forces, which sought to occupy the peninsula and disarm the former allies. The nation was plunged into civil war, with the Italian Co-Belligerent Army fighting alongside the Allies in the north while German troops and the puppet Republic of Salò fought to maintain control.
