Platformism is a form of anarchist organization that seeks unity from its participants, having as a defining characteristic the idea that each platformist organization should include only people that are fully in agreement with core group ideas, rejecting people who disagree. It stresses the need for tightly organized anarchist organizations that are able to influence working class and peasant movements.[1]

Symbol of platformism based on the CNT

Platformist groups reject the model of Leninist vanguardism, instead aiming to "make anarchist ideas the leading ideas within the class struggle".[2] According to platformism, the four main principles by which an anarchist organisation should operate are ideological unity, tactical unity, collective responsibility and federalism.
