Class struggle in the context of "International Workingmen's Association"

Marxism is a political philosophy and method of socioeconomic analysis that uses a dialectical materialist interpretation of historical development, known as historical materialism, to understand class relations and social conflict. Originating in the works of 19th-century German philosophers Karl Marx and Friedrich Engels, the Marxist approach views class struggle as the central driving force of historical change.

Marxist analysis views a society's economic mode of production as the foundation of its social, political, and intellectual life, a concept known as the base and superstructure model. In its critique of capitalism, Marxism posits that the ruling class (the bourgeoisie), who own the means of production, systematically exploit the working class (the proletariat), who must sell their labour power to survive. This relationship, according to Marx, leads to alienation, periodic economic crises, and escalating class conflict. Marx theorised that these internal contradictions would fuel a proletarian revolution, leading to the overthrow of capitalism and the establishment of a socialist mode of production. For Marxists, this transition represents a necessary step towards a classless, stateless communist society.

The Spanish Civil War (Spanish: guerra civil española) was fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic and included socialists, anarchists, communists, and separatists. The opposing Nationalists who established the Spanish State were an alliance of fascist Falangists, monarchists, conservatives, and traditionalists supported by Nazi Germany and Fascist Italy and led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war was variously viewed as class struggle, a religious struggle, or a struggle between dictatorship and republican democracy, between revolution and counterrevolution, or between fascism and communism. The Nationalists won the war, which ended in early 1939, and ruled Spain until Franco's death in November 1975.

The war began after the partial failure of the coup d'état of July 1936 against the Popular Front government by a group of generals of the Spanish Republican Armed Forces. The Nationalist faction consisted of right-wing groups, including Christian traditionalist party CEDA, monarchists, including both the opposing Alfonsists and the religious conservative Carlists, and the Falange Española de las JONS, a fascist political party. However, rebelling units in almost all important cities did not gain control, leaving Spain militarily and politically divided. The rebellion was countered with the help of arming left-wing social movements and parties and formation of militias, what led to rapid socioeconomic and political transformation in the Republican zone, referred to as the Spanish Revolution. The Nationalist forces received munitions, soldiers, and air support from Fascist Italy and Nazi Germany while the Republican side received support from the Soviet Union and Mexico. Other countries, such as the United Kingdom, France, and the United States, continued to recognise the Republican government but followed an official policy of non-intervention. Despite this policy, tens of thousands of citizens from non-interventionist countries directly participated in the conflict, mostly in the pro-Republican International Brigades.

Capital: A Critique of Political Economy (German: Das Kapital. Kritik der politischen Ökonomie), also known as Das Kapital (German: [das kapiˈtaːl]), is a foundational theoretical text in Marxist philosophy, economics, and politics by Karl Marx. His magnum opus, the work is a critical analysis of political economy, meant to reveal the economic patterns underpinning the capitalist mode of production. Das Kapital is in three volumes, of which only the first was published in Marx's lifetime (1867); the others were completed from his notes and published by his collaborator Friedrich Engels in 1885 and 1894.

The central argument of Das Kapital is that the motivating force of capitalism is in the exploitation of labour, whose unpaid work is the ultimate source of surplus value and profit. Beginning with an analysis of the commodity, Marx argues that the capitalist mode of production is a historically specific system where social relations are mediated by commodity exchange. He posits a labour theory of value, contending that the economic value of a commodity is determined by the socially necessary labour time required for its production. Under this system, the worker's capacity to labour (their labour power) is sold as a commodity, but its use-value—the ability to create new value—is greater than its exchange-value (the wage), allowing the capitalist to extract surplus value. This process drives capital accumulation, which in turn fosters technological change, the creation of a reserve army of labour, and a long-term tendency of the rate of profit to fall, leading to economic crises and intensifying class conflict.

The Eighteenth Brumaire of Louis Napoleon (German: Der 18te Brumaire des Louis Napoleon) is an essay written by Karl Marx between December 1851 and March 1852, and originally published in 1852 in Die Revolution, a German monthly magazine published in New York City by Marxist Joseph Weydemeyer. Later English editions, such as the 1869 Hamburg edition with a preface by Marx, were entitled The Eighteenth Brumaire of Louis Bonaparte. The essay serves as a major historiographic application of Marx's theory of historical materialism.

The Eighteenth Brumaire focuses on the 1851 French coup d'état, by which Louis-Napoléon Bonaparte, president of the Second Republic and Napoléon Bonaparte's nephew, became emperor of the Second French Empire as Napoleon III. It seeks to explain how capitalism and class struggle created conditions which enabled "a grotesque mediocrity to play a hero's part". Marx describes the divisions and alliances among the bourgeoisie, the petty bourgeoisie, the peasantry, revolutionaries, and social democrats, among other groups, and how a lack of dominance of any one group led to the re-emergence of monarchy, despite the Revolution of 1848. Marx describes the Second Empire as a "Bonapartist" state, an exception to the basic Marxist conception of the state as an instrument of class rule in that the Bonapartist state becomes semi-autonomous, representing the interests of no single class.

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.

Marxist philosophy or Marxist theory are works in philosophy that are strongly influenced by Karl Marx's materialist approach to theory, or works written by Marxists. Marxist philosophy may be broadly divided into Western Marxism, which drew from various sources, and the official philosophy in the Soviet Union, which enforced a rigid reading of what Marx called dialectical materialism, in particular during the 1930s. Marxist philosophy is not a strictly defined sub-field of philosophy, because the diverse influence of Marxist theory has extended into fields as varied as aesthetics, ethics, ontology, epistemology, social philosophy, political philosophy, the philosophy of science, and the philosophy of history. The key characteristics of Marxism in philosophy are its materialism and its commitment to political practice as the end goal of all thought.The theory is also about the struggles of the proletariat and their reprimand of the bourgeoisie.

Marxist theorist Louis Althusser, for example, defined the philosophy as "class struggle in theory", thus radically separating himself from those who claimed philosophers could adopt a "God's eye view" as a purely neutral judge.
