Hello!
Theory of scientific socialism was based on historical materialism where reality is a constant struggle between social classes and that this generated changes in society, in the same way it identified the collective subject of the socialist revolution with the industrial proletariat.
Scientific socialism is the name by which we sought to distinguish the Marxism of Karl Marx and Engels from other socialist currents of the mid-nineteenth century, which by not including theoretical-scientific premises are qualified as utopian socialism.
the theories of utopian socialism emerge in response to the same socio-economic context: the Industrial Revolution, the rule of the bourgeoisie and the rise of the workers' movement, events that were initially manifested in England at the end of the eighteenth century and that spread across the European continent during the nineteenth century.
I hope that it can help you!
Regards!
