Treaty of Nissa

Peace treaty signed on October 3, 1739 in Nissa by the Ottoman Empire on one side and Russia on the other. The Russo-Ottoman war in 1736-1739 was the result of Russian effort to regain Azov and the Crimea as a first step to dominating the Black Sea. In several successful raids led by Marshal Munich, Russians break the resistance of Tatars, cross the river Dniester into Moldavia and in 1739 march as far south along the Black Sea coast as Jassy, which they capture. Austria enters war in 1737 on the Russian side to get their share, but then make peace with Ottomans at the separate Treaty of Belgrade, surrendering Serbia to Ottomans to leave them in position to resist Russian push toward Istanbul. In return, Sultan is forced to acknowledge Austrian Emperor as official representative for all Ottoman Christian subjects, a position also claimed by Russia. Austrian pullout forced Russia also to accept peace at Nissa, by which Russia gave up the Crimea and Moldavia, is allowed to build port at Azov but is not allowed to build fortifications there, and is not allowed any fleet on the Black Sea.
