Southern Bessarabia

Southern Bessarabia or South Bessarabia is a territory of Bessarabia which, as a result of the Crimean War, was returned to the Moldavian Principality in 1856. As a result of the unification of the latter with Wallachia, these lands became part of United Principalities of Moldova and Wallachia.

In 1878, despite opposition from Romania, the Berlin Treaty, which followed the Russo-Turkish War (1877–1878), transferred this region back to the Russian Empire (which reintegrated it into the Bessarabia Governorate).

The transfer of the territory took place in October 1878. From 13 to 18 October, Russia took over Southern Bessarabia while the Romanian officials withdrew. In 1918 Southern Bessarabia yet again became part of the Kingdom of Romania (under the informal name of Bugeac) for the following 22 years (1918-1940) respectively between June 1941 and 1944.
