The history of communism is closely linked to the thought that the Prussian philosopher Karl Marx used the difficult situation of government as a springboard to communism. This saw communism as the optimal state, abolition of private ownership of the means of production. For Marx, only after humanity was able to produce excessively, private property would develop massively and permanently. However, in the West, communism was an idea of a society based on common property, an idea that goes back even from classical antiquity. Its modern form as a mass political movement emerged in Europe with the movement of workers during the Industrial Revolution in the 19th century.
Class struggle and political revolution is necessary for socialism to emerge. They think that everyone will just adopt it, without struggle or a fight, if it's represented convincingly.
