The Nogai Horde sprang up in 1391-1399 as a consequence of disintegration of the Golden Horde in the inter-river area of the Volga River (Nog. "the Idel’"), the Ural River ("the Zaik" or "the Jaik") and the Emba River ("the Jem"), in other words, in the West of the modern Kazakhstan. Though direct descendants of Nogai nomads turned out residents of many other territories, the 600th anniversary both of the famous Nogai epos "Edige", adopted by some other Turks, and of the Nogai Horde itself as a state was officially celebrated in the Nogai Region of the Dagestan Republic in the Northern Caucasus, November 15-17, 1991.
