Nor did Marx publish the "Theses on Feuerbach" during his lifetime. This material was instead later edited by Friedrich Engels and published in February 1888 as a supplement to his pamphlet Ludwig Feuerbach and the End of Classical German Philosophy.[7] Marx's original unedited text was published only in 1924 in German and Russian translation as part of Marx-Engels Archives, Book I, by the Marx-Engels Institute in Moscow.[8]
