1943–1945

The Italian Campaign and the Fall of Mussolini

Why did Italy become a battlefield of both war and civil conflict until 1945 after leaving the war in 1943?

The Italian Campaign was the Mediterranean theatre of the Second World War, beginning with the Allied invasion of Sicily in July 1943 and ending with the surrender of German forces in Italy in May 1945. After defeat in North Africa and sustained bombing, parts of the Fascist regime and the monarchy concluded that continuing the war would destroy the state, while the Allies sought to remove Italy from the war and tie down German forces in the south. After Sicily fell, the Fascist Grand Council deposed Benito Mussolini, and Pietro Badoglio's government signed the Armistice of Cassibile on 3 September. When announced on 8 September, German forces occupied central and northern Italy and rescued Mussolini, who established the Italian Social Republic. Allied troops landed at Salerno and Taranto, but the Apennines, Gustav Line, Anzio, and Monte Cassino made the advance costly. Rome fell in June 1944, yet fighting continued at the Gothic Line. In April 1945, the Allied offensive and a partisan uprising broke the northern front. Mussolini was captured and executed, and German Army Group C surrendered on 2 May.

Consequences

The campaign removed Italy from the Axis alliance, but it did not produce immediate liberation. German occupation, the Italian Social Republic, the royal government, and resistance networks turned the war into both an occupation conflict and an Italian civil war. Civilians, soldiers, Jews, and partisans paid the costs of reprisals, bombing, and combat. Liberation in 1945 destroyed Fascist rule, but did not immediately abolish the monarchy or established state institutions, leaving the resistance to contest postwar legitimacy. The dispute over Mediterranean strategy connects to the opening of a European front examined in The Second Front and the Normandy Landings.
