Transnistria (also called Trans-Dniestr or Transdniestria) is a breakaway territory located mostly on a strip of land between the River Dniester and the eastern Moldovan border with Ukraine. Since its declaration of independence in 1990, and especially after the War of Transnistria in 1992, it is governed as the Pridnestrovian Moldavian Republic (PMR, also known as Pridnestrovie), a state with limited recognition, which claims the territory to the east of the River Dniester, the city of Bender, and its surrounding localities located on the west bank.
