Between the middle of April and the end of May 1871, London resident Karl Marx collected and compiled English, French, and German newspaper clippings on the progress of the French civil war, which pitted the radical workers of Paris against conservative forces from outside the city.[1] Marx had access to French publications supported by the Commune as well as various bourgeois periodicals published in London in English and French. Marx also had access to personal interpretations of events passed along by several leading figures in the Commune and associates such as Paul Lafargue and Peter Lavrov.[2]
