Karl Marx (1818-83) was a German political philosopher. He was born in Trier, Germany, to liberal Jewish parents who had converted to Protestantism in order to advance the law career of his father. In 1836, after a year at the University of Bonn, Marx entered the University of Berlin, where he concentrated on philosophy. Deeply influenced by Hegelian thought, he was a member of a student group known as the Young Hegelians, who espoused a radical, atheistic version of Hegel’s The Phenomenology of the Spirit (1807).
