Georges Sorel in the context of "Édouard Berth"

Fascist movements in Europe were the set of various fascist ideologies which were practiced by governments and political organizations in Europe during the 20th century. Fascism was born in Italy following World War I, and other fascist movements, influenced by Italian fascism, subsequently emerged across Europe. Among the political doctrines which are identified as ideological origins of fascism in Europe are the combining of a traditional national unity and revolutionary anti-democratic rhetoric which was espoused by the integral nationalist Charles Maurras and the revolutionary syndicalist Georges Sorel.

The earliest foundations of fascism in practice can be seen in the Italian Regency of Carnaro, led by the Italian nationalist Gabriele D'Annunzio, many of whose politics and aesthetics were subsequently used by Benito Mussolini and his Italian Fasces of Combat which Mussolini had founded as the Fasces of Revolutionary Action in 1914. Despite the fact that its members referred to themselves as "fascists", the ideology was based around national syndicalism. The ideology of fascism would not fully develop until 1921, when Mussolini transformed his movement into the National Fascist Party, which then in 1923 incorporated the Italian Nationalist Association. The INA established fascist tropes such as colored shirt uniforms and also received the support of important proto-fascists like D'Annunzio and nationalist intellectual Enrico Corradini.

Sorelianism is advocacy for the support of the ideology and thinking of Georges Sorel, a French revolutionary syndicalist. Sorelians oppose bourgeois democracy, the developments of the 18th century, the secular spirit, and the French Revolution, while supporting Classicism. A revisionist interpretation of Marxism, Sorel believed that the victory of the proletariat in class struggle could be achieved only through the power of myth and a general strike. To Sorel, the aftermath of class conflict would involve rejuvenation of both the bourgeoisie and the proletariat.

With the seeming failure of syndicalism, Sorel announced his abandonment of socialist literature in 1910, and claimed in 1914, using an aphorism of Benedetto Croce, that "socialism is dead" due to the "decomposition of Marxism". He became a supporter of Charles Maurras-style integral nationalism (maurrassisme) beginning in 1909, which he believed had similar moral aims to syndicalism despite being enemies materially. In this sense, Sorelianism is considered a precursor to fascism. However, Sorel became disillusioned with these ideas with World War I, and from 1918 until his death in 1922, became a supporter of the Russian Revolution and communism, believing them a revival of syndicalism.

Antonio Francesco Gramsci (UK: /ˈɡræmʃi/ GRAM-shee, US: /ˈɡrɑːmʃi/ GRAHM-shee; Italian: [anˈtɔːnjo franˈtʃesko ˈɡramʃi] ; 22 January 1891 – 27 April 1937) was an Italian Marxist philosopher and politician. He was a founding member and one-time leader of the Italian Communist Party. A vocal critic of Benito Mussolini and fascism, he was imprisoned in 1926, and remained in prison until shortly before his death in 1937.

During his imprisonment, Gramsci wrote more than 30 notebooks and 3,000 pages of history and analysis. His Prison Notebooks are considered a highly original contribution to 20th-century political theory. Gramsci drew insights from varying sources—not only other Marxists but also thinkers such as Niccolò Machiavelli, Vilfredo Pareto, Charles Darwin, Sigmund Freud, Friedrich Nietzsche, Pierre Joseph Proudhon, Georges Sorel, and Benedetto Croce. The notebooks cover a wide range of topics, including the history of Italy and Italian nationalism, the French Revolution, fascism, Taylorism and Fordism, civil society, the state, historical materialism, folklore, religion, and high and popular culture.
