Sultan Mahmud I ibn Mustafa II, who ruled from 1143 AH to 1168 AH (1730–1754 CE), and was succeeded by Ahmed III. ²

Al-Salabi says that he summoned the first European French adviser for military affairs, Alexander, the Count (Bonneval). ²

When Russia and Austria declared war on Poland and Russia occupied it, they fought the Ottoman state. Al-Salabi says that the Ottomans halted the advance of the Russians in Moldavia and the advance of Austria in Bosnia, Serbia and Wallachia, and defeated the Serbs and the Austrian armies, which withdrew. Austria then asked for peace through France, and the Treaty of Belgrade was signed in 1152 AH (1739 CE), in which it gave up Belgrade and the lands of Serbia and Wallachia. Russia pledged not to build ships on the Black Sea and to demolish the fortresses of the port of Azov. ²
