Excerpt from V.I. Lenin's "Marxism and Revisionism", 1908

In the sphere of politics, revisionism did really try to revise the foundation of Marxism, namely, the doctrine of the class struggle. Political freedom, democracy and universal suffrage remove the ground for the class struggle—we were told—and render untrue the old proposition of the Communist Manifesto that the working men have no country. For, they said, since the “will of the majority” prevails in a democracy, one must neither regard the state as an organ of class rule, nor reject alliances with the progressive, social-reform bourgeoisie against the reactionaries.
