A communist state (sometimes referred as workers' state) is a state that is usually administered and governed by a single party representing the proletariat, guided by Marxist–Leninist philosophy, with the aim of achieving communism. There have been several instances of Communist states with functioning political participation processes involving several other non-Party organisations, such as trade unions, factory committees, and direct democratic participation. The term "Communist state" is used by Western historians, political scientists and media to refer to these countries. However, contrary to Western usage, these states do not describe themselves as "communist" nor do they claim to have achieved communism; they refer to themselves as socialist states or workers' states that are in the process of constructing socialism.
Communist states can be administered by a single, centralised party apparatus, although countries such as the DPRK have several parties. These parties usually are Marxist–Leninist or some variation thereof (including Maoism in China and Juche in North Korea), with the official aim of achieving socialism and progressing toward communism. These states are usually termed by Marxists as dictatorships of the proletariat, or dictatorships of the working class, whereby the working class is the ruling class of the country, in contrast to capitalism, whereby the bourgeoisie is the ruling class.
