EDIRNE, TREATY OF

or Treaty of Adrianople

(September 14, 1829) Pact concluding the Russo-Turkish War of 1828–29.

Signed at Edirne (ancient Adrianople), Turkey, the treaty opened the Turkish straits to Russian shipping and granted Russia some territorial concessions. It strengthened Russia's position in Eastern Europe and weakened that of the Ottoman empire, and it foreshadowed the Ottoman empire's dependence on the European balance of power and the dismemberment of its Balkan possessions.
