Libertarian socialism

Libertarian socialism is an anti-authoritarian and anti-capitalist political current that emphasises self-governance and workers' self-management. It is contrasted from other forms of socialism by its rejection of state ownership and from other forms of libertarianism by its rejection of private property. Broadly defined, it includes schools of both anarchism and Marxism, as well as other tendencies that oppose the state and capitalism.

With its roots in the Age of Enlightenment, libertarian socialism was first constituted as a tendency by the anti-authoritarian faction of the International Workingmen's Association (IWA), during their conflict with the Marxist faction. Libertarian socialism quickly spread throughout Europe and the American continent, reaching its height during the early stages of the Russian Revolution of 1917 and particularly during the Spanish Revolution of 1936. Its defeat during these revolutions led to its brief decline, before its principles were resurrected by the New Left and new social movements of the late 20th century.

While its key principles of decentralisation, workers' control and mutual aid are generally shared across the many schools of libertarian socialism, differences have emerged over the questions of revolutionary spontaneity, reformism, and whether to prioritise the abolition of the state or of capitalism.
