Marx owed Hegel's dialetic idealism the fundamental inspiration for the formulation of his historial materialism and the concept of alienation, key points of philosophy.
Marx and Engels were exiled again in 1845 and moved to Brussels, where they wrote the Communist Manifiesto in 1848. Then they returned to Germany during 1848-49 revolutions, but after they were quashed Marx lived in exile in London for the rest of his life. He and his wife lived in extreme poverty, supported by Engel's business. The first volume of his great Das Kapital was published in 1867, the second and third appeared posthumously. Marx's ideas had a profound effect on world histroy. He tought that reality was historically constitued, containing internal conflicts that drive change. His most important philosophical works were The Economic and Philosophical Manuscripts, Theses on Feuerbach, German Ideology, The Poverty of Philosophy, Communist Manifiesto and Das Kapital.
