Revolution and Counter-Revolution in Germany is a book by Friedrich Engels, with contributions by Karl Marx. The book was written as a "series of articles about Germany from 1848 onwards." The project was first suggested to Karl Marx by Charles Dana, one of the editors of the New York Daily Tribune, in early 1851. The series first appeared in the Tribune between October 25, 1851 and October 23, 1852. It marked the beginning of regular contributions by Marx and Engels to the New York Daily Tribune that continued for a decade. Revolution and Counter-Revolution is an account of what happened in Prussia, Austria and other German states during 1848, describing the impact on both middle-class and working-class aspirations and on the idea of German unification. Events in Austria and Prussia are discussed, along with the role of the Poles and Czechs and Panslavism, which Engels was against. Also discussed is the Cologne Communist Trial, in which the defendants were acquitted after some of the evidence was shown to have been crudely forged.
