Eastern Bloc
group of socialist states of Central and Eastern Europe
The Eastern Bloc, also known as the Communist Bloc (Combloc), the Soviet Bloc, the Socialist Bloc and the Workers Bloc, was an unofficial coalition of communist states of Central and Eastern Europe, Asia, Africa, and Latin America that were aligned with the Soviet Union and existed during the Cold War (1947–1991). These states followed Marxism–Leninism and various forms of socialism and opposed the capitalist Western Bloc. The Eastern Bloc was often called the "Second World", while the term "First World" referred to the Western Bloc and "Third World" referred to the non-aligned countries that were mainly in Africa, Asia, and Latin America but also included the pre-1948 European Soviet ally Yugoslavia. Non-Marxist (yet still socialist) countries, such as the Arab socialist governments of the United Arab Republic, Iraq, Libya, Yemen, etc., are sometimes considered part of the bloc.
In Western Europe, the term 'Eastern Bloc' generally referred to the USSR and Central and Eastern European countries in the Warsaw Pact (East Germany, Poland, Czechoslovakia, Hungary, Romania, Bulgaria, and Albania). In Asia, the Eastern Bloc comprised Mongolia, Vietnam, Laos, Kampuchea, North Korea, South Yemen and China. In the Americas, the countries aligned with the Eastern Bloc were Cuba from 1961, and for a short period, Nicaragua and Grenada.
Terminology
The term Eastern Bloc was often used interchangeably with the term Second World. This broadest usage of the term would include not only Maoist China and Cambodia, but also short-lived Soviet satellites such as the Second East Turkestan Republic (1944–1949), the People's Republic of Azerbaijan (1945–1946) and the Republic of Mahabad (1946), as well as the Marxist–Leninist states straddling the Second and Third Worlds before the end of the Cold War: the People's Democratic Republic of Yemen (from 1967), the People's Republic of the Congo (from 1969), the People's Republic of Benin, the People's Republic of Angola and People's Republic of Mozambique from 1975, the People's Revolutionary Government of Grenada from 1979 to 1983, the Derg/People's Democratic Republic of Ethiopia from 1974, and the Somali Democratic Republic from 1969 until the Ogaden War in 1977. Although not Marxist–Leninist, leadership of Ba'athist Syria officially regarded their country as part of the Socialist Bloc and established a close economic, military alliance with the Soviet Union.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Eastern Bloc”, the useful work is to connect “group of socialist states of Central and Eastern Europe” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q170541. VIAF identifies the subject as 237256236. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1947, 1991, 1948 and 1961.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
