The town was conquered by Bayezid I, sultan of the Ottoman Empire, in his 1393 Danubian campaign. The construction of a fortress was begun here during the reign of Murad IV, but by 1650 only the fortress's foundation walls and towers were standing. In the 17th century, it occasionally served as the winter headquarters for the Grand Vizier of the Turks during their wars with Russia. The town's location near to the Black Sea made it a target for the Russian navy, the town was bombed by the Russians in 1854 during the Crimean War. In the mid-19th century, Babadag formed part of the region (sanjak) of Silistra within the "Bulgarian Government" (Danube Vilayet). Following the 1877–1878 war between the Ottoman and Russian empires, Babadag became part of independent Romania.
