Death of Benito Mussolini in the context of "Italian fascist"

Duce (/ˈduːtʃeɪ/ DOO-chay, Italian: [ˈduːtʃe]) is an Italian title, derived from the Latin word dux, 'leader', and a cognate of duke. National Fascist Party leader Benito Mussolini was identified by Fascists as Il Duce ('The Leader') of the movement since the birth of the Fasci Italiani di Combattimento in 1919. In 1925 it became a reference to the dictatorial position of Sua Eccellenza Benito Mussolini, Capo del Governo, Duce del Fascismo e Fondatore dell'Impero ('His Excellency Benito Mussolini, Head of Government, Leader of Fascism and Founder of the Empire'). Mussolini held this title together with that of President of the Council of Ministers: this was the constitutional position which entitled him to rule Italy on behalf of the king of Italy. Founder of the Empire was added for the exclusive use by Mussolini in recognition of his founding of an official legal entity of the Italian Empire on behalf of the king in 1936 following Italy's victory in the Second Italo-Ethiopian War. The position was held by Mussolini until 1943, when he was removed from office by the king and the position of Duce was discontinued, while Marshal Pietro Badoglio was appointed Presidente del Consiglio.

This position was the model which other fascist leaders adopted, such as the position of Führer by Adolf Hitler and Caudillo by Francisco Franco. In September 1943, Mussolini styled himself as the "Duce of the Italian Social Republic" (Italian: Duce della Repubblica Sociale Italiana), and held the position until the collapse of the Italian Social Republic and his execution in April 1945.

The Italian campaign of World War II, also called the Liberation of Italy following the German occupation in September 1943, consisted of Allied and Axis operations in and around Italy, from 1943 to 1945. The joint Allied Forces Headquarters (AFHQ) was operationally responsible for all Allied land forces in the Mediterranean theatre and it planned and led the invasion of Sicily in July 1943, followed in September by the invasion of the Italian mainland and the campaign in Italy until the surrender of the Axis forces in Italy in May 1945.

The invasion of Sicily in July 1943 led to the collapse of the Fascist Italian regime and the fall of Mussolini, who was deposed and arrested by order of King Victor Emmanuel III on 25 July. The new government signed an armistice with the Allies on 8 September 1943. However, German forces soon invaded northern and central Italy, committing several atrocities against Italian civilians and army units who opposed the German occupation and started the Italian resistance movement. Mussolini, who was rescued by German paratroopers, established a collaborationist puppet state, the Italian Social Republic (RSI), to administer the German-occupied territory. On 13 October 1943, the Allies recognized Italy as a co-belligerent in the war against Germany. Thereafter, the Italian Co-Belligerent Army and the Italian partisans fought alongside the Allies against German troops and the collaborationist National Republican Army; an aspect of this period is the Italian civil war. In the summer of 1944, after the Axis defeats at Cassino and Anzio, central Italy, including Rome, was liberated. Northern Italy was liberated following the final spring offensive and the general insurrection of Italian partisans on 25 April 1945. Mussolini was captured by the Italian resistance and summarily executed by firing squad. The campaign ended when Army Group C surrendered unconditionally to the Allies on 2 May 1945, one week before the formal German Instrument of Surrender. Both sides committed war crimes during the conflict, and the independent states of San Marino and Vatican City surrounded by Italian territory also suffered damage.
