Treaty of Bucharest (1812)
The Treaty of Bucharest between the Ottoman Empire and the Russian Empire, was signed on 28 May 1812, in Manuc's Inn in Bucharest, and ratified on 5 July 1812, at the end of the Russo-Turkish War of 1806–12.
Under its terms, the eastern half of the Principality of Moldavia, between Prut and Dniester Rivers, with an area of 45,630 km2 (17,617.8 sq mi) (Bessarabia), was ceded by the Ottoman Empire (to which Moldavia was a vassal) to Russia. Also, Russia obtained trading rights on the Danube.
In Transcaucasia, the Ottomans renounced their claims to most of western Georgia, but retained control of Akhalkalaki, Poti, and Anapa previously captured by the Russo-Georgian troops in the course of the war
