Aside from the loss of the Banat and the temporary loss of Belgrade (1717–1739), the Ottoman border on the Danube and Sava remained stable during the eighteenth century. Russian expansion, however, presented a large and growing threat. Accordingly, King Charles XII of Sweden was welcomed as an ally in the Ottoman Empire following his defeat by the Russians at the Battle of Poltava of 1709 in central Ukraine (part of the Great Northern War of 1700–1721). Charles XII persuaded the Ottoman Sultan Ahmed III to declare war on Russia.

The Russo-Ottoman War of 1710—1711, also known as the Pruth River Campaign, was a brief military conflict between the Tsardom of Russia and the Ottoman Empire. The main battle took place during 18-22 July 1711 in the basin of the Pruth river near Stănilești (Stanilesti) after Tsar Peter I entered the Ottoman vassal Principality of Moldavia, following the Ottoman Empire’s declaration of war on Russia. The ill-prepared 38,000 Russians with 5,000 Moldavians, found themselves surrounded by the Ottoman Army under Grand Vizier Baltaci Mehmet Pasha. After three days of fighting and heavy casualties the Tsar and his armies were allowed to withdraw after agreeing to abandon the fortress of Azov and its surrounding territory. The Ottoman victory led to the Treaty of the Pruth which was confirmed by the Treaty of Adrianople. Although the news of the victory was first received well in Constantinople, the dissatisfied pro-war party turned general opinion against Baltacı Mehmet Pasha, who was accused of accepting a bribe from Peter the Great. Baltacı Mehmet Pasha was then relieved from his office.
