Vanguardism

In the context of the theory of Marxist revolutionary struggle, vanguardism is a strategy whereby the most class-conscious and politically advanced sections of the proletariat or working class, described as the revolutionary vanguard, form organizations in order to draw larger sections of the working class towards revolutionary politics and serve as manifestations of proletarian political power against its class enemies.

In theory, the revolutionary vanguard is not intended to be an organization separate from the working class that attempts to place itself at the center of the movement and steer it in a direction consistent with its own ideology. It is instead intended to be an organic part of the working class that comes to socialist consciousness as a result of the dialectic of class struggle.

Vanguardism may also more generally refer to cooperation between avant-garde individuals advancing in any field. Innovative writers and artists are often described as being in the vanguard of development of new forms and styles of art.
