Reformism or Revolution?

To commemorate the anniversary of Rosa Luxemburg's murder in 1919, we republish the following introduction to a 2014 Mexican edition of her important work, Reform or Revolution. The legacy of this martyr for proletarian revolution endures through her ideas.

"The imperialist war is crushing the people and threatens to crush them completely. The petty-bourgeois democrats can perhaps stave off disaster for a while. But it is only the revolutionary proletariat that can prevent a tragic end."
