Karl Heinrich Marx (May 5, 1818 – March 14, 1883) was a 19th century philosopher, political economist, and revolutionary. Often called the father of communism, Marx was both a scholar and a political activist. He addressed a wide range of political as well as social issues, and is known for, amongst other things, his analysis of history. His approach is indicated by the opening line of the Communist Manifesto (1848): “The history of all hitherto existing society is the history of class struggles”. Marx believed that capitalism, like previous socioeconomic systems, will produce internal tensions which will lead to its destruction. Just as capitalism replaced feudalism, capitalism itself will be displaced by communism, a classless society which emerges after a transitional period in which the state would be nothing else but the revolutionary dictatorship of the proletariat.
