Authoritarian socialism, or socialism from above, is an economic and political system supporting some form of socialist economics while rejecting political pluralism. As a term, it represents a set of economic-political systems describing themselves as "socialist" and rejecting the liberal-democratic concepts of multi-party politics, freedom of assembly, habeas corpus, and freedom of expression, either due to fear of counter-revolution or as a means to socialist ends. Journalists and scholars have characterised several countries, most notably the Soviet Union, China, Cuba, and their allies, as authoritarian socialist states.
Contrasted to democratic socialist, social democratic, anti-statist, and libertarian forms of socialism, authoritarian socialism encompasses some forms of African, Arab and Latin American socialism. Although considered an authoritarian or illiberal form of state socialism, often referred to and conflated as socialism by critics and argued as a form of state capitalism by left-wing critics, those states were ideologically Marxist–Leninist and declared themselves to be workers' and peasants' or people's democracies. Academics, political commentators and other scholars tend to distinguish between authoritarian socialist and democratic socialist states, with the first represented in the Soviet Bloc and the latter represented by Western Bloc countries which have been democratically governed by socialist parties - such as Britain, France, Sweden and Western social-democracies in general, among others. Those who support authoritative socialist regimes are pejoratively known as tankies.
