Marxism is a left-wing to far-left method of socioeconomic analysis that uses a materialist interpretation of historical development, better known as historical materialism, to understand class relations and social conflict and a dialectical perspective to view social transformation. It originates from the works of 19th-century German philosophers Karl Marx and Friedrich Engels. As Marxism has developed over time into various branches and schools of thought, no single, definitive Marxist theory exists. In addition to the schools of thought which emphasize or modify elements of classical Marxism, various Marxian concepts have been incorporated and adapted into a diverse array of social theories leading to widely varying conclusions. Alongside Marx's critique of political economy, the defining characteristics of Marxism have often been described using the terms dialectical materialism and historical materialism, though these terms were coined after Marx's death and their tenets have been challenged by some self-described Marxists. Marxism has had a profound impact on global academia, having influenced many fields, including anthropology, archaeology, art theory, criminology, cultural studies, economics, education, ethics, film theory, geography, historiography, literary criticism, media studies, philosophy, political science, political economy, psychology, science studies, sociology, urban planning, and theatre. Overview Marxism seeks to explain social phenomena within any given society by analysing the material conditions and economic activities required to fulfill human material needs. It assumes that the form of economic organisation, or mode of production, influences all other social phenomena, including broader social relations, political institutions, legal systems, cultural systems, aesthetics and ideologies. These social relations and the economic system form a base and superstructure. As forces of production (i.e. technology) improve, existing forms of organising production become obsolete and hinder further progress. Karl Marx wrote: "At a certain stage of development, the material productive forces of society come into conflict with the existing relations of production or—this merely expresses the same thing in legal terms—with the property relations within the framework of which they have operated hitherto. From forms of development of the productive forces these relations turn into their fetters. Then begins an era of social revolution." These inefficiencies manifest themselves as social contradictions in society which are, in turn, fought out at the level of class struggle. Under the capitalist mode of production, this struggle materialises between the minority who own the means of production (the bourgeoisie) and the vast majority of the population who produce goods and services (the proletariat).
