Communism
Karl Marx said that for society to change into a communist way of living, there would have to be a period of change. During this period, the workers would govern society. This is called a dictatorship of the proletariat. Marx was very interested in the Paris Commune of 1870, when the workers of Paris ran the city after the Prussian Army defeated the French Army. He thought that this practical experience was more important than the theoretical views of the various radical groups.
