Makhnovism refers to various related political and economic theories elaborated by Ukrainian anarchistrevolutionary leader Nestor Makhno, and by other theorists (Peter Arshinov etc.) who claim to be carrying on Makhno's work. During Makhno's lifetime Makhnovism was anarchist, and opposed the state and political parties, as well as bureaucracy, and favoured highly decentralized communes run by peasants and workers. Makhnovism builds upon and elaborates the ideas of Peter Kropotkin, and serves as the philosophical basis for anarchist communism. It is also the philosophical basis for Makhno's contribution to platformism.
