The Fascist regime collapsed; King Victor Emmanuel III dismissed Mussolini and appointed Marshal Pietro Badoglio as Prime Minister. The Fascist Party was dissolved, its symbols banned. But the armistice was not a peace treaty—it was a military surrender that left a power vacuum the Germans instantly filled.
Rescued from captivity by German paratroopers (Operation Oak), Mussolini was installed as head of the *Repubblica Sociale Italiana* (RSI) in September 1943. Based in Salò on Lake Garda, this puppet state controlled northern and central Italy under German tutelage. It raised its own military divisions (the *Esercito Nazionale Repubblicano*) and a brutal secret police. The RSI lasted until April 1945, when Mussolini was captured and executed by partisans near Lake Como.
The Allies landed at Salerno (Operation Avalanche) on September 9, 1943, beginning a grueling 20-month campaign up the peninsula. The Gustav Line (Monte Cassino), the Anzio landing, the liberation of Rome (June 4, 1944), the Gothic Line, and the final Spring 1945 offensive were the major phases. The terrain, weather, and determined German defense made it one of the Western Front's costliest campaigns.
Simultaneously, a vicious civil war raged. The Italian Resistance (*Resistenza*)—communists, socialists, liberals, Catholics, monarchists, and autonomous bands—fought German occupiers and RSI fascists. It was a war of liberation, but also a class struggle and a settling of scores. Estimates suggest 50,000–70,000 partisans died; civilian casualties from reprisals (e.g., Marzabotto, Sant'Anna di Stazzema) were horrific. The RSI's collaborationist forces committed atrocities and deported Jews and political opponents.
On October 13, 1943, the Badoglio government declared war on Germany. The Italian Co-Belligerent Army (*Esercito Cobelligerante Italiano*) was formed from troops in the south, eventually fielding several combat groups (Cremona, Friuli, Folgore, Legnano) that fought under Allied command. Their contribution was politically vital for Italy's post-war standing.
Rome fell in June 1944; Florence in August; the Gothic Line was breached in April 1945. The general insurrection (April 25, 1945) liberated Milan, Turin, and Genoa before Allied troops arrived. Germany surrendered in Italy on May 2, 1945.
Italy emerged devastated: cities bombed, infrastructure ruined, society fractured. A 1946 institutional referendum abolished the monarchy (54% to 46%) and established the Republic. The 1948 Constitution, drafted by a Constituent Assembly, enshrined democratic principles. The Marshall Plan, land reform (partial), and the "economic miracle" of the 1950s-60s rebuilt the country, but the wounds of 1943–45—political, social, and moral—took decades to heal.
