New social movements in the context of "Libertarian socialist"

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.

The anti-nuclear movement is a social movement that opposes various nuclear technologies. Some direct action groups, environmental movements, and professional organisations have identified themselves with the movement at the local, national, or international level. Major anti-nuclear groups include Campaign for Nuclear Disarmament, Friends of the Earth, Greenpeace, International Physicians for the Prevention of Nuclear War, Peace Action, Seneca Women's Encampment for a Future of Peace and Justice and the Nuclear Information and Resource Service. The initial objective of the movement was nuclear disarmament, though since the late 1960s opposition has included the use of nuclear power. Many anti-nuclear groups oppose both nuclear power and nuclear weapons. The formation of green parties in the 1970s and 1980s was often a direct result of anti-nuclear politics.

Scientists and diplomats have debated nuclear weapons policy since before the atomic bombings of Hiroshima and Nagasaki in 1945. The public became concerned about nuclear weapons testing from about 1954, following extensive nuclear testing including the Castle Bravo disaster. In 1963, many countries ratified the Partial Test Ban Treaty which prohibited atmospheric nuclear testing.
