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.

Marcy and his followers split from the Socialist Workers Party (SWP) in 1958 over a series of long-standing differences, among them their support for Henry A. Wallace's Progressive Party in 1948, their view of People's Republic of China as a workers' state, and their defense of the 1956 Soviet intervention in Hungary, some of which the SWP opposed.
World revolution is the Marxist concept of overthrowing capitalism in all countries through the conscious revolutionary action of the organized working class. For theorists, these revolutions will not necessarily occur simultaneously, but where and when local conditions allow a revolutionary party to successfully replace bourgeois ownership and rule, and install a workers' state based on social ownership of the means of production. In most Marxist schools, such as Trotskyism and Communist Left, the essentially international character of the class struggle and the necessity of global scope are critical elements and a chief explanation of the failure of socialism in one country.
