context_section_description: The Treaty of Belgrade (Russian: Белградский мир) was the peace treaty signed on September 18, 1739 in Belgrade, Serbia, by the Ottoman Empire on one side and the Habsburg Monarchy on the other. This ended the hostilities of the two-year Austro-Turkish War, 1737-39, in which the Habsburgs joined Imperial Russia in its fight against the Ottomans. With the Treaty of Belgrade, the Habsburgs ceded Northern Serbia with Belgrade to the Ottomans, and Oltenia, gained by the Treaty of Passarowitz in 1718, to Wallachia (an Ottoman subject), and set the demarcation line to the rivers Sava and Danube. The Habsburg withdrawal forced Russia to accept peace at the Russo-Turkish War, 1735-1739 with the Treaty of Nissa, whereby it was allowed to build a port at Azov, gaining a foothold on the Black Sea.
  The Treaty of Niš is a peace treaty signed on October 3, 1739 in Nissa (ancient Nyssa, in Cappadocia) by the Ottoman Empire on one side and Russian Empire on the other. The Russo-Turkish War, 1735-1739 was the result of the Russian effort to gain Azov and Crimea as a first step towards dominating the Black Sea. In several successful raids led by Marshal Munich, the Russians broke the resistance of the Crimean Khanate, crossed the Dniester into Moldavia and in 1739 marched as far as the Moldavian capital of Iaşi (Jassy), which they captured. The Habsburg Monarchy entered the war in 1737 on the Russian side to get its share, but was forced to make peace with Ottomans at the separate Treaty of Belgrade, surrendering Northern Serbia, Northern Bosnia and Oltenia, and allowing the Ottomans to resist the Russian push toward Constantinople. In return, the Sultan acknowledged the Habsburg Emperor as the official protector of all Ottoman Christian subjects (see Ottoman millet), a position also claimed by Russia. The Austrian pullout forced Russia to accept peace at Niš, giving up its claims to Crimea and Moldavia, being allowed to build a port at Azov but not to build fortifications there or have any fleet in the Black Sea.
