Timeline of Karl Marx

He moved to Paris in 1843, where he began writing for other radical newspapers and met Fredrick Engels, who would become his lifelong friend and collaborator.

In 1845 he was exiled and moved to London together with his wife and children where he continued writing and formulating his theories about social and economic activity.

He argued that class antagonisms under capitalism between the bourgeoisie and proletariat would eventuate in the working class' conquest of political power in the form of a dictatorship of the proletariat and eventually establish a classless society, socialism or communism, a society governed by a free association of producers.

Many labour unions and workers' parties worldwide are influenced by Marxism, 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.
