Karl Marx was a German philosopher, economist, historian, and social theorist whose work laid the foundation for critical sociology and Marxist theory. Best known for his critique of capitalism and class society, Marx developed a materialist conception of history—historical materialism—that interprets social change as a result of conflicts between social classes over the control of the means of production.
His seminal works, including The Communist Manifesto (co-authored with Friedrich Engels, 1848) and Das Kapital (1867), analyze capitalism as a historically specific mode of production characterized by exploitation, alienation, and cyclical crises. Marx’s theory of surplus value remains central to critiques of capitalist economies.
Marx introduced key sociological concepts such as class struggle, base and superstructure, ideology, and commodity fetishism. His ideas have profoundly influenced a wide range of disciplines—from sociology and political science to economics, cultural studies, and literary theory.
While often associated with revolutionary movements, Marx was also a meticulous scholar whose work offers a systemic analysis of economic relations, power structures, and ideology. His influence extends to critical theory, conflict theory, and numerous contemporary approaches that investigate inequality, domination, and resistance.
Even more than a century after his death, Karl Marx remains one of the most cited and contested figures in the social sciences. His theories continue to inspire debates on capitalism, democracy, and social justice.
