The German Ideology
Marx's most important works on social and political history include "The Eighteenth Brumaire of Louis Napoleon" (1852), "The Communist Manifesto" (1848), "The German Ideology" (written in 1845, published in 1932), and those chapters of "Das Kapital" (1867-1894) dealing with the historical emergence of capitalists and proletarians from pre-industrial English society.
