History of socialism. The history of socialism has its origins in the French Revolution of 1789 and the changes which it wrought, although it has precedents in earlier movements and ideas. The Communist Manifesto was written by Karl Marx and Friedrich Engels in 1848 just before the Revolutions of 1848 swept Europe, expressing what they termed 'scientific socialism'.
In Marxist theory, socialism, also called lower-stage communism or the socialist mode of production, refers to a specific historical phase of economic development and its corresponding set of social relations that supersede capitalism in the schema of historical materialism.lthough Karl Marx and Friedrich Engels wrote very little on socialism and neglected to provide any details on how it might be organized, numerous social scientists and neoclassical economists have used Marx's theory as a basis for developing their own models of socialist economic systems.
