モルダビア・ソビエト社会主義共和国
The Pridnestrovian Moldavian Soviet Socialist Republic (PMSSR; ; ; ), also commonly known as Soviet Transnistria or simply known as Transnistria, was created on the eastern periphery of the Moldavian Soviet Socialist Republic (MSSR) in 1990 by pro-Soviet separatists who hoped to remain within the Soviet Union when it became clear that the MSSR would achieve independence from the USSR. The PMSSR was never recognised as a Soviet republic by authorities in either Moscow or Chișinău. In 1991, the Pridnestrovian Moldavian Republic succeeded the Pridnestrovian Moldavian Soviet Socialist Republic.
