An economic and political system
in which the economy
is designed to meet the needs of the people
, but the political power
is held by a certain group and/or individual. Any society
which is socialist
, but non-democratic. Many would claim that true socialism
requires democracy by definition
Communism, as envisioned by Marx and described as a "dictatorship of the proletariat" is authoritarian socialism, although not a true dictatorship. Not all communism is authoritarian, as the anarcho-communists will tell you.
Cuba is an example of an authoritarian socialist state.
