Moldova is split into two main regions, Bessarabia and Transnistria. Bessarabia is in the eastern part of historic Moldova and is mostly Romanian while Transnistria is the land on the eastern bank of the Nistru River and is mostly Slavic (Ukrainians and Russians). After the Russo-Turkish War in 1806-12, Bessarabia ceded to Russia. Finally on Aug. 27, 1991, Moldova declared its independence from the USSR and was recognized by the United States in December of that same year as they opened an embassy in its capital in 1992. A new constitution was adopted on July 28, 1994, which forever replaced the Soviet Union's constitution and was a symbol of the complete break away from the USSR.
