The Communist Manifesto and Das Kapital are two of the most important publications of the 19th century, hugely influential to the present day. Both were written by Karl Marx, in cooperation with Friedrich Engels. Both were translated in practically every language, and published world-wide. These writings had a tremendous impact on the development of socialist, communist and other revolutionary movements throughout the 19th and 20st century. The writings of Marx and Engels were rigidly interpreted and used to justify repression and the absolute control of the state over the individual. In many African, Asian and Latin American countries, Marxism was a main source of inspiration for liberation movements.
