Explanation:
Karl Heinrich Marx (1818 - 83) is a German social philosopher. In 1845 he went to Brussels, joined the Socialist League of the just in 1847, later renamed the Communist League, and in conjunction with Engels wrote for it the communist manifesto (1848). He envisaged a global political and social revolution as a result of the conflict between the working classes and the capitalists, who used the state to enforce their own dominance. His goal was to unite all workers in order to achieve political power. Marx's theories were developed at length in Das Kapital (1867; ed. by Engels) and inspired the communist movements of the 20th century. At the heart of Marxism lies the materialist conception of history, according to which the development of all human societies is ultimately determined by the methods of production that people adopt to meet their needs.
