What happened
Italy entered the Second World War alongside Nazi Germany, with Mussolini's fascist regime declaring war on France and Great Britain on June 10, 1940, and later on the Soviet Union and the United States. Military defeats and the Allied invasion of Sicily turned opinion against the regime, and on July 25, 1943, the Fascist Grand Council itself voted no confidence in Mussolini; King Victor Emmanuel III had him arrested the same day. The new Italian government surrendered unconditionally to the Allies on September 3, 1943, and by late September had become, in the words of General Eisenhower, a co-operator with the Allied powers, formally declaring war on Germany on October 13, 1943. German forces freed Mussolini and installed him as the nominal head of a puppet state, the Italian Social Republic based at Salo, while Italy itself split into a war zone between advancing Allied troops, German occupying forces, and Italian anti-fascist partisans. As Allied and partisan forces liberated northern Italy in April 1945, Mussolini was captured near Lake Como while attempting to flee to Switzerland and was shot by partisans on April 28, 1945; his body was publicly displayed in Milan.
Why it matters
Italy's abrupt switch from Axis partner to a country fighting itself, with fascist, royalist, German-occupying, and partisan forces all active on Italian soil at once, left deep and lasting divisions over collaboration and resistance that shaped the postwar republic's politics for decades. The war itself, its other fronts, and the wider Axis collapse are covered on the World War II timeline.
How we know
Italy's declarations of war, the July 1943 overthrow of Mussolini, and the September 1943 armistice terms are documented in official U.S. State Department historical records describing the Allied side of these negotiations, and Mussolini's capture and execution are corroborated by multiple independent historical accounts of the final days of the war in northern Italy.
