On October 28, 1922, Benito Mussolini, who had started his Fascist Party in 1919, knew the time was ripe for change. He gathered 50,000 supporters for a march on Rome. Inflation was soaring and workers had just called a general strike, so rather than recognizing a state under siege, King Victor Emmanuel III recognized Mussolini as the new government leader. In 1929, Il Duce defined the divisions between the Italian government and the Vatican by signing a concordat granting political and fiscal autonomy to Vatican City. It also made Roman Catholicism the official state religion -- but that designation was removed in 1978 through a revision of the concordat.
During the Spanish Civil War (1936-39), Mussolini's support of Franco's Fascist Party, which staged a coup against the democratically elected government of Spain, helped encourage the formation of the "Axis" alliance between Italy and Nazi Germany. Despite its outdated military equipment, Italy added to the general horror of the era by invading Abyssinia (Ethiopia) in 1935. In 1940, Italy invaded Greece through Albania, and in 1942 it sent thousands of Italian troops to assist Hitler in his disastrous campaign along the Russian front. In 1943, Allied forces, under the command of U.S. Gen. George Patton and British Gen. Bernard Montgomery, landed in Sicily and quickly secured the island as they prepared to move north toward Rome.
In the face of likely defeat and humiliation, Mussolini was overthrown by his own cabinet (Grand Council). The Allies made a separate deal with Victor Emmanuel III, who had collaborated with the fascists during the previous 2 decades and now easily shifted allegiances. A politically divided Italy watched as battalions of fanatical German Nazis released Mussolini from his Italian jail cell to establish the short-lived Republic of Salò, headquartered on the edge of Lake Garda. Mussolini had hoped for a groundswell of popular opinion in favor of Italian fascism, but events quickly proved this nothing more than a futile dream.
In April 1945, with almost half a million Italians rising in a mass demonstration against him and the German war machine, Mussolini was captured by Italian partisans as he fled to Switzerland. Along with his mistress, Claretta Petacci, and several others of his intimates, he was shot and strung upside-down from the roof of a Milan gas station.
