The Moldavian Soviet Socialist Republic or Moldavian SSR (Romanian: Republica Sovietică Socialistă Moldovenească, Moldovan Cyrillic: Република Советикэ Сочиалистэ Молдовеняскэ), also known as the Moldovan Soviet Socialist Republic, Moldovan SSR, Soviet Moldavia, Soviet Moldova, or simply Moldavia or Moldova, was one of the 15 republics of the Soviet Union that existed from 1940 to 1991. The republic was formed on 2 August 1940 from parts of Bessarabia, a region annexed from Romania on 28 June of that year, and parts of the Moldavian Autonomous Soviet Socialist Republic, an autonomous Soviet republic within the Ukrainian SSR.
From the Moldavian Soviet Socialist Republic Supreme Soviet's adoption of the declaration of sovereignty on 23 June 1990 to 23 May 1991, the country was internationally recognized as the Soviet Socialist Republic of Moldova. Furthermore, from 23 May 1991 until the declaration of independence on 27 August 1991, it was renamed to the Republic of Moldova while remaining a constituent republic of the USSR. Its independence was officially recognized by the international community on 26 December of that year when the USSR was dissolved.
