The Treaty of Jassy, signed at Jassy (Iași) in Moldavia (presently in Romania), was a pact between the Russian and Ottoman Empires ending the Russo-Turkish War of 1787–92[1] and confirming Russia's increasing dominance in the Black Sea.

It confirmed the Treaty of Küçük Kaynarca of 1774, wherein the Ottomans had ceded suzerainty over the Crimean Khanate to Russia.

[3] Yedisan (the territory between Dniester and Bug rivers) was transferred to Russia, establishing the Dniester as the Russo-Turkish frontier in Europe, while leaving the Asiatic frontier (Kuban River) unchanged.

[4] The Ottomans also acknowledged Georgia (the Kingdom of Kartli-Kakheti) as a Russian protectorate.

[3] The signing of peace was strongly influenced by the storming of the Ottoman fortress of Izmail by commander Alexander Vasilyevich Suvorov-Rymniksky.
