Koca Yusuf Pasha was an Ottoman statesman. He was grand vizier from 25 January 1786 to 28 May 1789 (during reign of Abdul Hamid I), and Kapudan Pasha (Grand Admiral of the Ottoman Navy) after 19 December 1789. He became grand vizier again, this time serving from 12 February 1791 until mid-1792 (during reign of Selim III). He is considered to be one of the best Ottoman commanders of his time period,
He was a Georgian convert to Islam and also served as the governor of the Peloponnese.
The Treaty of Jassy, signed at Iași (Jassy) in Moldavia (present-day Romania), was a pact between the Russian and Ottoman Empires ending the Russo-Turkish War of 1787–92 and confirming Russia's increasing dominance in the Black Sea.
The treaty was signed on 9 January 1792 (O.S.: 29 December 1791) by Grand Vizier Koca Yusuf Pasha and Prince Bezborodko (who had succeeded Prince Potemkin as the head of the Russian delegation when Potemkin died). It confirmed the Treaty of Küçük Kaynarca of 1774, wherein the Ottomans had ceded suzerainty over the Crimean Khanate to Russia. Yedisan (the territory between Dniester and Southern Bug rivers) was transferred to Russia, establishing the Dniester as the Russo-Turkish frontier in Europe, while leaving the Asiatic frontier (Kuban River) unchanged. The Ottomans also acknowledged Georgia (the Kingdom of Kartli-Kakheti) as a Russian protectorate.
