Marxists have taken various stances regarding patriotism. On one hand, Karl Marx famously stated that "The working men have no country" and that "the supremacy of the proletariat will cause them differences to vanish still faster." The same view is promoted by present-day Trotskyists such as Alan Woods, who is "in favour of tearing down all frontiers and creating a socialist world commonwealth." On the other hand, Marxist-Leninists and Maoists are usually in favor of socialist patriotism based on the theory of socialism in one country.
