The Russo-Turkish War was a conflict between the Ottoman Empire and a coalition led by the Russian Empire which included Romania, Serbia, and Montenegro.

The Ottoman Empire was founded c. 1299 by Osman I as a small beylik in northwestern Asia Minor just south of the Byzantine capital Constantinople. In 1326, the Ottomans captured nearby Bursa, cutting off Asia Minor from Byzantine control. The Ottomans first crossed into Europe in 1352, establishing a permanent settlement at Çimpe Castle on the Dardanelles in 1354 and moving their capital to Edirne (Adrianople) in 1369. At the same time, the numerous small Turkic states in Asia Minor were assimilated into the budding Ottoman sultanate through conquest or declarations of allegiance.
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.

The Ottomans had done poorly in the war. The Sublime Porte above all wanted to stay out of the impending conflict between Napoleon's France and Russia. The Russians did not want a war on two fronts, thus they made peace in order to be free for the upcoming war with France. The Ottomans had extricated themselves from a potentially disastrous war with a slight loss of territory. This treaty became the basis for future Russo-Ottoman relations.
