Founded in Rome during the Third Fascist Congress on 7–10 November 1921, the National Fascist Party transformed from a previously paramilitary group to a more cohesive political group.
Mussolini’s new right-wing organization advocated Italian nationalism, had black shirts for uniforms, and launched a program of terrorism and intimidation against its leftist opponents. By October 1922, Italy seemed to be slipping into political chaos. The Black Shirts marched on Rome and Mussolini presented himself as the only man capable of restoring order. King Victor Emmanuel invited Mussolini to form a government. Mussolini gradually dismantled the institutions of democratic government and in 1925 made himself dictator, taking the title 'Il Duce'.
He set about attempting to re-establish Italy as a great European power. The regime was held together by strong state control and Mussolini's cult of personality.In 1935, Mussolini invaded Abyssinia (now Ethiopia) and incorporated it into his new Italian Empire. He provided military support to Franco in the Spanish Civil War. Increasing co-operation with Nazi Germany culminated in the 1939 Pact of Steel. Influenced by Hitler, Mussolini began to introduce anti-Jewish legislation in Italy. His declaration of war on Britain and France in June 1940 exposed Italian military weakness and was followed by a series of defeats in North and East Africa and the Balkans.
In July 1943, Allied troops landed in Sicily. Mussolini was overthrown and imprisoned by his former colleagues in the Fascist government. In September, Italy signed an armistice with the Allies. The German army began the occupation of Italy and Mussolini was rescued by German commandos. He was installed as the leader of a new government, but had little power. As the Allies advanced northwards through Italy, Mussolini fled towards Switzerland. He was captured by Italian partisans and shot on 28 April 1945.
