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'.
Engels later argued that utopian socialists failed to recognize why it was that socialism arose in the historical context that it did, that it arose as a response to new social contradictions of a new mode of production, i.e. capitalism.his shift in socialism was seen as complimentary to shifts in contemporary biology sparked by Charles Darwin and the understanding of evolution by natural selection; Marx and Engels saw this new understanding of biology as essential to the new understanding of socialism, and vice versa.
