Neosocialism was a political faction that existed in France and Belgium during the 1930s and which included several revisionist tendencies in the French Section of the Workers' International (SFIO). During the 1930s, the faction gradually distanced itself from revolutionary Marxism and reformist socialism while stopping short of merging into traditional class-collaborative socialism of radical-socialist progressivism. Instead, they advocated a revolution from above which they termed as a constructive revolution. In France, this brought them into conflict with the Socialist Party's traditional policy of anti-governmentalism and the neosocialists were expelled from SFIO. From the start, this linked them to fascist politics in France and many neosocialists expressed admiration for Italian Fascism. This tendency later emerged as an ideological orientation in its own right with the Neosocialist Party which advocated authoritarianism and antisemitic policies as well as intimate cooperation with the Nazis. History In the wake of the Great Depression, a group of deputies led by Henri de Man in Belgium (the leader of the Belgian Labour Party's right-wing, and founder of the ideology of planisme, i.e. planism, meaning economic planning) and in France by Marcel Déat and Pierre Renaudel (leader of the SFIO's right wing), René Belin of the General Confederation of Labour, the Young Turk current of the Radical-Socialist Party (Pierre Mendès-France) argued that the unprecedented scale of the global economic crisis, and the sudden success of national-populist parties across Europe, meant that time had run out for socialists to slowly pursue either of the traditional stances of the parliamentary left: gradual, progressive reformism or Marxist-inspired popular revolution. Instead, influenced by Henri de Man's planism, they promoted a "constructive revolution" headed by the state, where a democratic mandate would be sought to develop technocracy and a planned economy. This approach saw great success in the Belgian Labour Party in 1933-1934, where it was adopted as official policy with the support of the party's right (De Man) and left (Paul-Henri Spaak) wings, though by 1935 enthusiasm had waned. Such ideas also influenced the non-conformist movement on the French right. Marcel Déat published in 1930 Perspectives socialistes (Socialist Perspectives), a revisionist work closely influenced by Henri de Man's planism. Along with over a hundred articles written in La vie socialiste (The Socialist Life), the review of the SFIO's right-wing, Perspective socialistes marked the shift of Déat from classical socialism to neosocialism. Déat replaced class struggle with class collaboration and national solidarity, advocated
