The tsarist government was a capitalism based system, the economic system based on private enterprise. Marx says that capitalism contains the seeds of it's own destruction, and must eventuallybe replaced with communism. Communism is a socioeconomic order in which private property has been abolished and people live without social divisions. Marx even thinks world communism is historically inevitable. According to Marx, communism must be reached in two steps, capitalism to socialism and socialism to communism.
Socialism is the intermediate transition from capitalism to communism.

For years Lenin gained more and more knowledge of Communism, and gradualy provocted the citizens of Russia toward revolution. One of Lenin's most famous works of his own was called What Is To Be Done .
