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 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 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.

Sir Charles Spencer "Charlie" Chaplin, KBE (16 April 1889 – 25 December 1977) was an English comic actor, film director and composer best known for his work during the silent film era. He became the most famous film star in the world before the end of World War I. Chaplin used mime, slapstick and other visual comedy routines, and continued well into the era of the talkies, though his films decreased in frequency from the end of the 1920s. His most famous role was that of The Tramp, which he first played in the Keystone comedy Kid Auto Races at Venice in 1914. From the April 1914 one-reeler Twenty Minutes of Love onwards he was writing and directing most of his films, by 1916 he was also producing them, and from 1918 he was even composing the music for them. With Mary Pickford, Douglas Fairbanks and D. W. Griffith, he co-founded United Artists in 1919.

Chaplin was one of the most creative and influential personalities of the silent-film era. He was influenced by his predecessor, the French silent film comedian Max Linder, to whom he dedicated one of his films. His working life in entertainment spanned over 75 years, from the Victorian stage and the music hall in the United Kingdom as a child performer, until close to his death at the age of 88. His high-profile public and private life encompassed both adulation and controversy. Chaplin was identified with left-wing politics during the McCarthy era and he was ultimately forced to resettle in Europe from 1952.
