As the 1983 American Heritage Dictionary noted, fascism is: “A system of government that exercises a dictatorship of the extreme right, typically through the merging of state and business leadership, together with belligerent nationalism.”...Mussolini was quite straightforward about all this. In a 1923 pamphlet titled “The Doctrine of Fascism” he wrote, “If classical liberalism spells individualism, Fascism spells government.” But not a government of, by, and for We The People—instead, it would be a government of, by, and for the most powerful corporate interests in the nation.

Historically, Italian Fascism was founded as a Marxist-leaning party, which some have classified as a form of Fascist-Marxist ideology. From 1914 to at least 1921, Mussolini simultaneously proclaimed himself a Fascist while still adhering to Marxist doctrines and Marxist leaders such as Lenin. In 1914, Mussolini created the Marxist-sounding organization—the Fasci of Revolutionary Action (Fasci d'Azione Rivoluzionaria, FAR). Mussolini’s first Fascist party—the Fascist Revolutionary Party (Partito Fascista Rivoluzionario, PFR)—was founded in 1915. Two years later, Mussolini still considered himself within the Marxist camp, praising the Bolshevik’s 1917 October Revolution, boasting of his camaraderie with Lenin and violent revolution. In the Italian elections of 1919, he publicly compared himself to Lenin, bragging that he was the ‘Lenin of Italy.’

Mussolini insisted that Fascism was the only form of ‘socialism’ appropriate to the ‘proletarian nations’ of the twentieth century.

Because of Italian fascism’s roots in revolutionary syndicalism (labor unionism) and revised Marxism, Mussolini never thought of himself as a rightist; that label was already reserved for the reactionary forces of the monarchy and the clergy. According to the Encyclopedia Americana, Mussolini’s Fasci di Combattimento (combat groups) declared that they were trying to start a ‘leftist revolutionary program of action.’

"..."fascist" is quite simply a word of disapprobiation. The Communists, you surely have noticed, refer to anyone who disagrees with any...any hemidemimisemiquaver in the Communist line as a fascist. Or a proto-fascist. Or a neo-fascist. It has nothing whatever to do with the political disciplines practiced by Mussolini."

In 1925, Mussolini adopted the term [totalitarian] and assigned it a positive meaning. He defined Fascism as ‘totalitarian’ in the sense that it politicized everything ‘human’ as well as ‘spiritual’: ‘Everything within the state, nothing outside the state, nothing against the state.’

Mussolini’s Fascism was a relatively benign form of reactive nationalism—in terms of the regime’s treatment of its domestic population. In the years between 1926 and 1932, when Fascism was establishing its totalitarianism, the special Fascist tribunals for political offenders pronounced only 7 death sentences.

[Italian] Fascism was a variant of classical Marxism, a believe system that pressed some themes argued by both Marx and Engels until they found expression in the form of ‘national syndicalism’ that was to animate the first Fascism.”

Fascism was born of the reaction of the particular against the universal, the national against the international. In its origins it was inseparable from Communism, fighting the latter’s goals even while adopting its methods… Communism and Fascism grew up on the same soil, the soil of Italian Socialism. The founder of the fasci in March 1919, Mussolini was a member of the revolutionary wing of the Socialist movement prior to supporting Italy's entry into the Great War; then, immediately afterward, he found himself in violent conflict with the Bolshevik-leaning leaders of his former party.

Despite the fact that three-fourths of Italy’s economic sector was owned by the government by the mid-1930s, most scholars routinely ignored Italian Fascism’s slide into pure Soviet-style socialism, a concentration of state ownership so large that it was only eclipsed by Stalin’s Soviet Union. The conventional definition of socialism is described as a social and economic system characterized by ‘public ownership’ of the ‘means of production.’ On the other hand, fascism is often explained as a social and economic system characterized by ‘public control’ over the ‘agents of production.’ But Mussolini’s regime eventually morphed into Fascist socialism as its means of production was placed under public ownership.

"The word fascism is not a word of abuse any more than the word capitalism is. It is a concept denoting a very definite kind of mass leadership and mass influence: authoritarian, one-party system, hence totalitarian, a system in which power takes priority over objective interests, and facts are distorted for political purposes. Hence, there are "fascist Jews," just as there are "fascist Democrats.

Fascism is anti-Marxism which seeks to destroy the enemy by the evolvement of a radically opposed and yet related ideology and by the use of almost identical and yet typically modified methods, always, however within the unyielding framework of national self-assertion and autonomy. This definition implies that without Marxism there is no fascism, that fascism is at the same time closer to and further from communism than is liberal anti-communism, that it necessarily shows at least an inclination toward a radical ideology, that fascism should never be said to exist in the absence of at least the rudiments of an organization and propaganda comparable to those of Marxism.

The fascist movement in Italy was a spontaneous movement of large masses, with new leaders from the rank and file. It is a plebian movement in origin, directed and financed by big capitalist powers. It issued forth from the petty bourgeoisie, the slum proletariat, and even to a certain extent from the proletarian masses; Mussolini, a former socialist, is a "self-made" man arising from this movement.

Italian Fascist theories of corporatism arose out of revolutionary and national syndicalism that often paralleled the activities of the trade unions, craft guilds and professional societies. Mussolini acknowledged Fascism’s socialist roots and influences. Among those whom he acknowledged as influencing Fascism were French Marxist Georges Sorel and French Revolutionary Unionist Hubert Lagardelle. Moreover, Mussolini was a union man: he decreed mandatory unionism for all Italian workers. It is true that Mussolini banned strikes, but Lenin had done the same in the Soviet Union.
