Karl Heinrich Marx (May 5, 1818 Trier, Germany – March 14, 1883 London) was an immensely influential German philosopher, political economist, and revolutionary organizer of the International Workingmen's Association. While Marx addressed a wide range of issues, he is most famous for his analysis of history in terms of class struggles, summed up in the opening line of the introduction to the Communist Manifesto: "The history of all hitherto existing society is the history of class struggle."
Marx's thought was strongly influenced by:
- The dialectical method and historical orientation of Georg Wilhelm Friedrich Hegel;
- The classical political economy of Adam Smith and David Ricardo;
- French socialist and sociological thought, in particular the thought of Jean-Jacques Rousseau.
Marx believed that he could study history and society scientifically and discern tendencies of history and the resulting outcome of social conflicts. Some followers of Marx concluded, therefore, that a communist revolution is inevitable. However, Marx famously asserted in the eleventh of his Theses on Feuerbach that "philosophers have only interpreted the world, in various ways; the point however is to change it", and he clearly dedicated himself to trying to alter the world. Consequently, most followers of Marx are not fatalists, but activists who believe that revolutionaries must organize social change.
