The Greeks' struggle for independence sparked the Russo-Turkish War of 1828-1829, in which Russian forces advanced into Bulgaria, the Caucasus, and northeastern Anatolia itself before the Turks sued for peace. The resulting Treaty of Adrianople (Edirne) in September 14, 1829 gave Russia most of the eastern shore of the Black Sea and the mouth of the Danube. Turkey recognized Russian sovereignty over Georgia and parts of present-day Armenia. Serbia achieved autonomy and Russia was allowed to occupy Moldavia and Walachia (guaranteeing their prosperity, and full "liberty of trade" for them) until Turkey had paid a large indemnity.
