The Communist Correspondence Committee (German: Kommunistisches Korrespondenz-Komitee) was an association in the Anglo-French area, of communists founded by Karl Marx and Friedrich Engels, with committees in Brussels, London, Cologne, and Paris, with the aim of politically and ideologically organising socialists of different countries to form a revolutionary proletarian party.
The first committee was formed in Brussels which became the headquarters of the Correspondence Committee, with members including Karl Marx, Wilhelm Wolff, Joseph Weydemeyer, Edgar von Westphalen, Ferdinand Wolff, and Philip Giot.
[2] Engels, who went to France in 1846 upon the committee’s assignment, led the struggle against Pierre-Joseph Proudhon's reformist influence, the “true socialism,” of Karl Grün and "Weitlingism" or better known as the levelling communism of Wilhelm Weitling among Paris workers.
[3] From 1846 to 1847, Heinrich Bürgers and Roland Daniels worked in Cologne for the Correspondence Committee and the physician Georg Weber in Kiel.
The traveling salesman and poet Georg Weerth also worked as a courier for the committees.
