Context paragraphs:
Benito Mussolini: Benito Amilcare Andrea Mussolini ( ; ] ; 29 July 1883 – 28 April 1945) was an Italian politician, journalist and leader of the National Fascist Party ("Partito Nazionale Fascista"; PNF), ruling the country as Prime Minister from 1922 to 1943—constitutionally until 1925, when he dropped all pretense of democracy and set up a legal dictatorship.

Duce: Duce (] , "leader") is an Italian title, derived from the Latin word "dux", and cognate with "duke".  National Fascist Party leader Benito Mussolini was identified by Fascists as "Il Duce" ("The Leader") of the movement.  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 dismantled, while Marshal Pietro Badoglio was appointed Presidente del Consiglio.

Manifesto of the Fascist Intellectuals: The Manifesto of Fascist Intellectuals ("Manifesto degli Intellettuali del Fascismo", ] ), by the actualist philosopher Giovanni Gentile, formally establishes the political and ideologic foundations of Italian Fascism.  It justifies the political violence of the Blackshirt paramilitaries of the National Fascist Party (PNF — "Partito Nazionale Fascista"), in the revolutionary realisation of Italian Fascism as the authoritarian and totalitarian rėgime of Prime Minister Benito Mussolini, who ruled Italy as "Il Duce" ("The Leader"), from 1922 to 1943.

March on Rome: The March on Rome (Italian: "Marcia su Roma" ) was an organized mass demonstration in October 1922 which resulted in Benito Mussolini's National Fascist Party ("Partito Nazionale Fascista", or PNF) acceding to power in the Kingdom of Italy ("Regno d'Italia").  In late October 1922 Fascist Party leaders planned an insurrection, to take place on 28 October.  When facisct troops entered Rome, Prime Minister Luigi Facta wished to declare a state of siege, but this was overruled by the king.  On the following day, 29 October 1922, the king appointed Mussolini as Prime Minister, thereby transferring political power to the fascists without armed conflict.

Filippo Andrea VI Doria Pamphili: Filippo Andrea VI Doria Pamphili (March 1, 1886 – February 3, 1958) was an Italian politician.  He was born into the Doria Pamphili family in Rome, Kingdom of Italy.  He became the 1st mayor of Rome after its liberation in World War II, after his predecessor, a member of the National Fascist Party and its successor the Republican Fascist Party, fled to the territory of the Italian Social Republic.  He died in Rome, Italy.

Congress of Verona (1943): The Congress of Verona in November 1943 was the only congress of the Italian Republican Fascist Party, the successor of the National Fascist Party.  At the time, the Republican Fascist Party was nominally in charge of the Italian Social Republic, a small fascist state set up in Northern Italy after the Allies entered Rome.  The Salò Republic was in fact a German puppet state and most of its internal and external policies were dictated by German military commanders.  Nevertheless, Italian fascists were allowed to keep the trappings of sovereignty.  It was under these conditions that they organized the Congress of Verona, ostensibly for the purpose of charting a new political course and rejuvenating the Italian fascist movement.

Giovanni Orgera: Giovanni Orgera (December 14, 1894 – December 12, 1967) was an Italian politician.  He was born in Naples, Kingdom of Italy.  He was mayor of Naples (1936–1943) as a member of the National Fascist Party.  He was mayor of Rome from January to June 1944 as a member of the Republican Fascist Party.  He later went to Desenzano del Garda, Province of Brescia, Lombardy as a supporter of the Italian Social Republic.  He died in Rome, Italy.

Italian Fascism: Italian Fascism (Italian: "fascismo italiano" ), also known simply as Fascism (Italian: "fascismo" ), is the original Fascist ideology, as developed in Italy.  The ideology is associated with a series of three political parties led by Benito Mussolini: the Fascist Revolutionary Party (PFR), founded in 1915, the succeeding National Fascist Party (PNF) which was renamed at the Third Fascist Congress on 7-10 November 1921 and ruled the Kingdom of Italy from 1922 until 1943, and the Republican Fascist Party that ruled the Italian Social Republic from 1943 to 1945.  Italian Fascism is also associated with the post-war Italian Social Movement and subsequent Italian neo-fascist movements.

Argentine Fascist Party: The Argentine Fascist Party (Partido Fascista Argentino, PFA) was a fascist political party in Argentina from 1932 until its official disbandment in 1936, when it was succeeded by the National Fascist Union ("Union Nacional Fascista", UNF).  Founded by Italian Argentines, the party was formed as a breakaway faction from Argentina's National Fascist Party ("Partido Nacional Fascista", PNF).  It was based upon Italian Fascism and was recognized by Benito Mussolini's Italian National Fascist Party in 1935.  In the 1930s the party became a mass organization, particularly in Córdoba.  Nicholás Vitelli led the PFA's branch in Córdoba until his death in 1934, whereafter Nimio de Anquín took the leadership of the party.  The PFA's main political allies in Córdoba were the Argentine Civic Legion and the Nationalist Action of Argentina/Affirmation of a New Argentina movement.

Yugoslav Radical Union: The Yugoslav Radical Union (, Југословенска радикална заједница; Slovene: "Jugoslovanska radikalna skupnost" ; or JRZ) was a political party founded by Yugoslav Prime Minister Milan Stojadinović in 1935 as the ruling party of Yugoslavia that sponsored authoritarian mass mobilization.  The party, whose agenda was based upon fascism, was the dominant political movement in the country until 1939, when Stojadinović was removed as Prime Minister.  Party members wore green shirt uniforms and addressed Stojadinović as "Vođa" ("Leader").  Stojadinović told Italian foreign minister Galeazzo Ciano that although the party was initially established as a moderate authoritarian movement, his intention was to model the party after the Italian National Fascist Party.
