context_page_description: The Russo-Turkish wars were a series of twelve wars fought between the Russian Empire and the Ottoman Empire between the 17th and 20th centuries. It was one of the longest series of military conflicts in European history. Except for the war of 1710–11 and the Crimean War, which is often treated as a separate event, the conflicts ended disastrously for the stagnating Ottoman Empire; conversely they showcased the ascendancy of Russia as a European power after the modernisation efforts of Peter the Great in the early 18th century.
context_section_description: Russia joined the European Holy League (Austria, Poland, Venice) in 1686. During the war, the Russian army organized the Crimean campaigns of 1687 and 1689 and the Azov campaigns (1695–96). The Russian involvement marked the beginning of the Russo-Turkish Wars. In the light of Russia's preparations for the war with Sweden and other countries' signing the Treaty of Karlowitz with Turkey in 1699, the Russian government signed the Treaty of Constantinople with the Ottoman Empire in 1700.
  After the Russians had defeated the Swedes and the pro-Swedish Empire Ukrainian Cossacks led by Ivan Mazepa in the Battle of Poltava in 1709, Charles XII of Sweden managed to persuade the Ottoman Sultan Ahmed III to declare war on Russia on November 20, 1710.
  By the late 17th century, the Iranian Safavid dynasty, which neighbored both empires and had been one of the greatest rivals for Turkey for centuries (16th–19th centuries), had been heavily declining. Taking advantage of the situation, Russia and the Ottoman Empire conquered swaths of its territory comprising contemporary Dagestan, Azerbaijan, and Northern Iran, which was taken by Peter I in the Russo-Persian War (1722–1723); the Ottomans took the territory to the west, comprising modern day Armenia, parts of Eastern Anatolia, as well as western Iran. The gains by both were confirmed in the Treaty of Constantinople (1724). For a few years, they bordered each other along a large territory in the Caucasus, which caused further frictions.
  Russia managed to secure a favourable international situation by signing treaties with Persia in 1732 and 1735. These returned all Iranian territories gained since 1722 in the North and South Caucasus and Northern Iran, and avoided war with the emerging leader of Persia, Nader Shah. The treaties had other diplomatically favourable aspects as they established a Russo-Iranian alliance against Turkey, as Persia was at war with the Ottoman Empire. In the meantime Russia was also supporting the accession to the Polish throne of Augustus III in the War of the Polish Succession (1733–35), over the French-nominated Stanisław Leszczyński. Austria had been Russia's ally since 1726.
  Russia entered into another war with the Ottoman Empire in 1736, prompted by raids on Ukraine by Crimean Tatars and the military campaign of the Crimean khan in the Caucasus. In May 1736, the Russian army launched an invasion of the Crimean peninsula. On June 19, the Russian Don army (28,000 men) under the command of General Peter Lacy seized the Azov Fortress with the support of the Don Flotilla under the command of Vice Admiral Peter Bredahl. In July 1737, the Münnich army took by storm the Ottoman fortress of Ochakov. The Lacy army (now 40,000 strong) marched into the Crimea the same month, inflicting a number of defeats on the army of the Crimean khan and capturing Karasubazar. Lacy and his soldiers had to leave the Crimea, however, due to lack of supplies.
  Austria entered the war against Turkey in July 1737 but was defeated a number of times. In August, Russia, Austria and Turkey began negotiations in Nemirov, which would turn out to be fruitless. There were no significant military operations in 1738. The Russian army had to leave Ochakov and Kinburn due to a plague outbreak. In 1739, the Münnich army crossed the Dnieper, defeated the Ottoman Empire at Stavuchany, and occupied the fortress of Khotin (August 19) and Iaşi. However, Austria was defeated by the Ottoman Empire once again and signed a separate peace treaty on August 21. This, coupled with the imminent threat of Swedish invasion, forced Russia to sign the Treaty of Belgrade with Turkey on September 18, ending the war.
