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.
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."
Karl Heinrich Marx was a German philosopher, economist, historian, sociologist, political theorist, journalist, critic of political economy, and socialist revolutionary. His best-known titles are the 1848 pamphlet The Communist Manifesto and the four-volume Das Kapital (1867–1883). Marx's political and philosophical thought had enormous influence on subsequent intellectual, economic, and political history. His name has been used as an adjective, a noun, and a school of social theory.
Friedrich Engels was a German philosopher, critic of political economy, historian, political theorist and revolutionary socialist. He was also a businessman, journalist and political activist, whose father was an owner of large textile factories in Salford (Lancashire, England) and Barmen, Prussia (now Wuppertal, Germany).
Engels developed what is now known as Marxism together with Karl Marx. In 1845, he published The Condition of the Working Class in England, based on personal observations and research in English cities. In 1848, Engels co-authored The Communist Manifesto with Marx and also authored and co-authored (primarily with Marx) many other works. Later, Engels supported Marx financially, allowing him to do research and write Das Kapital. After Marx's death, Engels edited the second and third volumes of Das Kapital. Additionally, Engels organised Marx's notes on the Theories of Surplus Value which were later published as the "fourth volume" of Das Kapital. In 1884, he published The Origin of the Family, Private Property and the State on the basis of Marx's ethnographic research.
The International Workingmen's Association (IWA), often called the First International (1864–1876), was an international organisation which aimed at uniting a variety of different left-wing socialist, communist and anarchist groups and trade unions that were based on the working class and class struggle. It was founded in 1864 in a workmen's meeting held in St. Martin's Hall, London. Its first congress was held in 1866 in Geneva.
In Europe, a period of harsh reaction followed the widespread Revolutions of 1848. The next major phase of revolutionary activity began almost twenty years later with the founding of the IWA in 1864. At its peak, the IWA reported having 8 million members while police reported 5 million. In 1872, it split in two over conflicts between statist and anarchist factions and dissolved in 1876. The Second International was founded in 1889.
