Insurrectionary Communism, is a 
Communist tendency that seeks to achieve communism through Insurrection.
Insurrectionary Communism is quite different from most communist tendencies, and can be differentiated through its refusal of the very concept of revolution. Rather than attempting to dismantle the present state and construct a new one, Insurrectionary Communism seeks to abolish all repressive social relations and free desire through a process of insurrection. This process, distinct from the naive utopianism of anarchist communism, is inherently a process; it is not some ideal that is immediately realized. To insurrectionary communists, communism can only exist as a lived process rather than a heaven to be brought into existence.
Insurrectionary Communism views itself as a movement to abolish the present state of things, rather than the proletarian movement. It is not a proletarian movement simply because it seeks to dissolve rather than affirm the proletarian condition. Insurrectionary Communism possesses a unique perspective on violence drawing from Sorel and Newman, promoting anti-capitalist, liberating violence based on self-affirmation and liberation as opposed to the disciplinary guillotine logic of the Jacobins.
