List of socialist states

This article is about self-proclaimed socialist states. For countries governed by Marxist–Leninist communist parties, see Communist state.

Several past and present states have declared themselves socialist states or in the process of building socialism. The majority of self-declared socialist countries have been Marxist–Leninist or inspired by it, following the model of the Soviet Union or some form of people's or national democracy. They share a common definition of socialism and they refer to themselves as socialist states on the road to communism with a leading vanguard party structure, hence they are often called communist states. Meanwhile, the countries in the non-Marxist–Leninist category represent a wide variety of different interpretations of the term socialism and in many cases the countries do not define what they mean by it. Modern uses of the term socialism are wide in meaning and interpretation.

Because a sovereign state is a different entity from the political party that governs that state at any given time, a country may be ruled by a socialist party without the country itself claiming to be socialist or the socialist party being written into the constitution. This has occurred in both one-party and multi-party political systems. In particular, there are numerous cases of social democratic and democratic socialist parties winning elections in liberal democratic states and ruling for a number of terms until a different party wins the elections. While socialist parties have won many elections around the world and most elections in the Nordic countries, none of those countries has adopted socialism as a state ideology or written the party into the constitution.

Several countries with liberal democratic constitutions mention socialism. India is a democracy that has been governed by non-socialist parties on many occasions, but its constitution makes references to socialism. Certain other countries such as Hungary, Myanmar, and Poland have constitutions that make references to their communist and socialist past by recognizing or condemning it, but without claiming to be socialist in the present.

Overview

Self-identification is the only criterion used by the list, therefore it includes all countries that have claimed to be socialist, even if their claims are disputed. All countries that have not claimed to be socialist are excluded, even in cases where certain outside observers regarded those countries as socialist. Mao Zedong and the Communist Party of China considered the Taiping Heavenly Kingdom to be a proto-communist state, although the kingdom never declared itself socialist, hence it is not included on this list. The list includes countries that assert in their constitutions that they are based on socialism, regardless of their economic or political system. It does not list countries that do not have constitutional references to socialism as socialist states, even in cases where the government is currently run by a socialist party or other left-wing (centre-left and far-left) parties. Inversely, countries that do maintain constitutional references to socialism are listed, even when those countries are governed by non-socialist parties. The list is best understood as a list of countries that explicitly claim to be socialist and it does not reflect the actual economic systems themselves.

A combined map of all countries that declared themselves socialist states under any definition at some point in their history, color-coded for the number of years they said they were socialist:
  •   Over 70 years
  •   60–70 years
  •   50–60 years
  •   40–50 years
  •   30–40 years
  •   20–30 years
  •   10–20 years
  •   Under 10 years
States that had communist governments in red, states that the Soviet Union believed at one point to be moving toward socialism in orange and other socialist states in yellow. Not all of the bright red states remained Soviet allies:
  States that have or had a socialist government
  States that the Soviet Union believed to be moving toward socialism
  States with constitutional references to socialism

States with governing communist or socialist parties (alone or as part of a coalition)

See also: List of communist parties, List of democratic socialist parties and organizations, List of social democratic and democratic socialist parties that have governed, List of socialist parties with national parliamentary representation, List of social democratic parties, and List of left-wing political parties

There are multiple states with communist or socialist parties leading the government, sometimes together. Such states are not considered to be communist or socialist states because the countries themselves do not provide a constitutional role for their ruling socialist/communist parties or deem socialism a state ideology. This does not include socialist parties following social democracy which governed most of the Western world as part of the mainstream centre-left and refers to democratic socialist parties positioned to their left.
