What's the difference between Communism and Marxism?

In my opinion non if the rot's at the top . whether singular or plural none .most governments are out for them selves only difference is cost ..In England we have a Queen and a government .

Communism is a socioeconomic structure that promotes the establishment of a classless, stateless society based on common ownership of the means of production. It is usually considered to be a branch of socialism, a broad group of social and political ideologies, which draws on the various political and intelectual movements with origins in the work of theories of  the INDUSTRIAL REVOLUTION and the FRENCH REVOLUTION, although socialist historians say they are older. Communism states that the only way  to solve the problems would be for the working class, or proletariat, to replace the wealthy bourgeoisie, in order to  establish a peaceful, free society, without classes, or government.
            Marxism is the political philosophy and practice derived from the work of KARL MARX and FRIEDRIC ENGELS. Any politica practice or theory that is based on an interpretation of the work of Marx and Engels may be called Marxism.
              The constitution of the Communist Parties and Communist States was grounded in Marxism; the basic difference between Communism in general and Marxism, is that Communism aims at the realization of a Communist society, while Marxism is a theoritical-practical framwork based on the analysis of ''the conflicts between the powerful and subjugated''.
                         Every system have a good and a bad effect, good result improve the position of the society and bad effect hamper the position. So it is a very controversial question that it is good or bad in today's corruopted worled, because all these corrupton done by us and all these system also created by us.
