World revolution

World revolution is the Marxist concept of overthrowing capitalism in all countries through the conscious revolutionary action of the organized working class. These revolutions would not necessarily occur simultaneously, but where and when local conditions allowed 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, 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.

The end goal of such internationally oriented revolutionary socialism is to achieve world socialism, and later, stateless communism.

The October Revolution of 1917 in Russia sparked a revolutionary wave of socialist and communist uprisings across Europe, most notably the German Revolution, the Hungarian Revolution, Biennio Rosso and the revolutionary war in Finland with the short lived Finnish Socialist Workers' Republic, which made large gains and met with considerable success in the early stages; see also Revolutions of 1917-23.
