Who is Karl Marx and Vladimir Lenin from The Rebel and what is their importance?

Karl Marx was the socio-political-economic philosopher whose theories and prophecies were the groundwork of Soviet socialism, and later communism.

Lenin was a politician and reformer who refined (some would say corrupted) Marx's beliefs into the philosophy that gave rise to Communism and the Soviet Union. His philosophy essentially recreated the age-old master/slave relationship into uneducated proletariat and educated leaders who maintained control, over both the revolution and those whom the revolution was intended to benefit, by any means available, violent or otherwise.
