Far-left politics are politics further to the left on the political spectrum than the standard political left. The far-left encompasses a wide range of heterogeneous ideologies, mainly anarchism and communism; it includes groups that advocate for revolutionary socialism and related communist ideologies, as well as anti-capitalism and anti-globalisation. The modern far-left distinguishes itself from social democracy through its inherent opposition to capitalism, neoliberalism, and globalisation. Anarchist strains of far-left thought are anti-authoritarian in nature, and most far-left schools of thought aim at a classless, stateless society. Leninist-led revolutions advocated for the eventual withering away of the state through a transitional socialist phase, though mainstream Western scholarship and historians generally characterize the resulting governance structures as authoritarian.
