The Mass Strike. Rosa Luxemburg

Marx once wrote to a friend that he did not feel his contribution was the discovery of the material underpinnings of politics nor the existence of class conflict but rather identifying the central role that the working class was to play in the struggle toward socialism. Luxemburg felt that the role of a party was to support the spontaneous movement of the working class toward that goal. For her spontaneous did not mean impulsive as in unplanned but rather organic, beyond the capacity of a party to predict, but which a party must engage, educate, and support. A quick and good read.
