After the Austro-Turkish War of 1716–1718 the Treaty of Passarowitz confirmed the loss of the Banat, Serbia and "Little Walachia" (Oltenia) to Austria. The Treaty also revealed that the Ottoman Empire was on the defensive and unlikely to present any further aggression in Europe. The Austro-Russian–Turkish War, which was ended by the Treaty of Belgrade in 1739, resulted in the recovery of Serbia and Oltenia, but the Empire lost the port of Azov, north of the Crimean Peninsula, to the Russians.

True
