Marx’s theories about society, economics and politics—collectively known as Marxism—hold that all societies progress through the dialectic of class struggle: a conflict between an ownership class which controls production and a lower class which produces the labour for such goods. Heavily critical of the current socio-economic form of society, capitalism, he called it the “dictatorship of the bourgeoisie“, believing it to be run by the wealthy classes purely for their own benefit, and predicted that, like previous socioeconomic systems, it would inevitably produce internal tensions which would lead to its self-destruction and replacement by a new system, socialism.^[5] He argued that under socialism society would be governed by the working class in what he called the “dictatorship of the proletariat“, the “workers state” or “workers’ democracy”.^[6][7] He believed that socialism would, in its turn, eventually be replaced by a stateless, classless society called communism. Along with believing in the inevitability of socialism and communism, Marx actively fought for the former’s implementation, arguing that both social theorists and underprivileged people should carry out organised revolutionary action to topple capitalism and bring about socio-economic change.^[8][9]

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 worker’s parties worldwide were also influenced by Marxist ideas. Various theoretical variants, such as Leninism, Stalinism, Trotskyism and Maoism, were developed. Marx is typically cited, with Émile Durkheim and Max Weber, as one of the three principal architects of modern social science.^[10] Marx has been described as one of the most influential figures in human history.^[11][12]
