The North Caucasus (Russian: Се́верный Кавка́з; IPA: [ˈsʲevʲɪrnɨj kɐfˈkas]) or Ciscaucasia is the northern part of the Caucasus region between the Sea of Azov and Black Sea on the west and the Caspian Sea on the east, within European Russia.
Geographically, the Northern Caucasus (territory north of the Greater Caucasus Range) includes the Russian republics and krais of the North Caucasus. As part of the Russian Federation, the Northern Caucasus region is included in the North Caucasian and Southern Federal Districts and consists of Krasnodar Krai, Stavropol Krai, and the constituent republics, approximately from west to east: the Republic of Adygea, Karachay–Cherkessia, Kabardino-Balkaria, North Ossetia–Alania, Ingushetia, Chechnya, and the Republic of Dagestan. The outer border of the Soviet Union's North Caucasus Krai was the same as that of present-day North Caucasus Economic Region (Raion) which includes an oblast (Rostov Oblast), two krais (Krasnodar Krai and Stavropol Krai), and seven republics. The former North Caucasus Military District (Okrug) also included Astrakhan Oblast, Volgograd Oblast, and the Republic of Kalmykia. Its administrative center was Rostov-on-Don until 10 January 1934, Pyatigorsk until January 1936, then Ordzhonikidze (today Vladikavkaz) and, from 15 December 1936, Voroshilovsk (today Stavropol).
