The Ottoman Empire signs the Treaty of Adrianople with Russia, thus ending the Russo-Turkish War.

The Ottoman Empire, also called the Turkish Empire, was an imperial realm that controlled much of Southeast Europe, West Asia, and North Africa from the 14th to early 20th centuries; it also controlled parts of southeastern Central Europe, between the early 16th and early 18th centuries.

The Treaty of Adrianople concluded the Russo-Turkish War of 1828–29, between Imperial Russia and the Ottoman Empire. The terms favored Russia, which gained access to the mouths of the Danube and new territory on the Black Sea. The treaty opened the Dardanelles to all commercial vessels, granted autonomy to Serbia, and promised autonomy for Greece. It also allowed Russia to occupy Moldavia and Walachia until the Ottoman Empire had paid a large indemnity; those indemnities were later reduced. The treaty was signed on 14 September 1829 in Adrianople by Count Alexey Fyodorovich Orlov of Russia and Abdülkadir Bey of the Ottoman Empire.

The Russo-Turkish War of 1828–1829 resulted from the Greek War of Independence of 1821–1829; war broke out after the Ottoman Sultan Mahmud II closed the Dardanelles to Russian ships and in November 1827 revoked the 1826 Akkerman Convention in retaliation for the participation of the Imperial Russian Navy in the Battle of Navarino of October 1827.
