According to communist theory, the only way to abolish capitalist inequalities is to have the proletariat (working class), who collectively constitute the main producer of wealth in society, and who are perpetually exploited and marginalised by the bourgeoisie (wealthy class), to overthrow the capitalist system in a wide-ranging social revolution.[7] The revolution, in the theory of most individuals and groups espousing communist revolution, usually involves an armed rebellion. The revolution espoused can be explained by theorists in many different ways, and usually depends on the environment in which the particular communism theory originates. For example, the Chinese Revolution involved military combat between the Chinese Red and the Chinese Nationalist Armies, while the Vietnamese Revolution was characterised by guerilla warfare between the heavily-backed Vietnam People's Army and various Western armies, culminating in the Vietnam War which ended in 1975. Meanwhile, the Cuban Revolution was essentially a coup that did not involve intensive wide-scale military conflict between Fulgencio Batista's soldiers and those of Fidel Castro and Che Guevara. In fact, Castro initially did not believe that a vanguard party was necessary in Cuba's case, a view boosted by Batista's unpopularity at the time of the actual armed conflict between the two sides. Regardless of the specific form a communist revolution takes, its aim is for the working class to replace the exploiter class as the ruling class to establish a society without class divisions, called socialism, as a prelude to attempting to achieve the final stage of communism
