Karl Marx was a philosopher, economist, sociologist, historian, journalist, and revolutionary socialist.
Marx was born into a wealthy family in the Rhineland-Palatinate in 1818, and later studied at the University of Bonn and the University of Berlin. He published many books, his best known being The Communist Manifesto. Marx also developed theories about society, economics, and politics, collectively referred to as Marxism. His philosophy holds that all societies progress through the dialect of class struggle. He also believed that capitalism was another form of dictatorship that would soon tear itself apart as tensions grow between classes within society. He believed socialism would replace capitalism, and the working class would gain control.
Marx dedicated his life to these ideas and was known by his friends as "the greatest living thinker." He died on 14 March, 1883.
