Most modern forms of communism are based upon
Marxism, a variant of the ideology formed by the sociologist
Karl Marx in the 1840s. Some religious societies that have stressed
egalitarianism and common ownership of goods have been described as communist, including
early Christianity and the
Shakers of 19th century America. Marxism subsequently gained support across much of Europe, and under the control of the
Bolshevik Party, a communist government seized power during the
Russian revolution, leading to the creation of the
Soviet Union, the world’s first Marxist state, in the early 20th century.
