MOZDOK, a town of Russia, in Caucasia, and in the province of Terek, on the left bank of the river Terek, 605 ft. above sea-level, in 43° 41′ N. and 44° 39′ E., 50 m. N. of Vladikavkaz. The population, 8760 in 1863, numbered 14,583 in 1897, and consisted of Kabardians, Chechens, Ossetes, Georgians and Armenians. Built in 1763 by the prince of Kabardia, Mozdok soon became an important point in the Russian advance towards the Caucasus, and was fortified. In 1840 it was attacked by the Circassian patriot Shamyl and 5000 mountaineers. The melons and water-melons of Mozdok are widely famed; and vine-growing and silkworm breeding prosper.
