Page "Karl Marx" Paragraph 3

Revolutionary socialist governments espousing Marxist concepts took power in a variety of countries in the 20th century, leading to the formation of such socialist states as the Soviet Union in 1922 and the People's Republic of China in 1949.

Many labor unions and workers ' parties worldwide were also influenced by Marxist ideas, while various theoretical variants, such as Leninism, Stalinism, Trotskyism, and Maoism, were developed from them.

Marx is typically cited, with Émile Durkheim and Max Weber, as one of the three principal architects of modern social science.

Marx has been described as one of the most influential figures in human history.
