Communism is also a political system as much an economic one—with various models in how it is implemented—the well known being the Marxist Leninist model, which argues for the use of a vanguard party to bring about a workers state to be used as a transitional tool to bring about stateless communism, the economic arrangement described above. Other models to bring about communism include anarcho-communism, which argues similarly to Marxist schools for a revolutionary transformation to the above economic arrangement, but does not use a transitional period or vanguard party.
