Nogai Horde, Nohai Horde or Nogai Yortu was a confederation of about eighteen Turkic and Mongol tribes that occupied the Pontic-Caspian steppe from about 1500 until they were pushed west by the Kalmyks and south by the Russians in the 17th century. The Mongol tribe called the Manghits constituted a core of the Nogai Horde. In the 13th century, the leader of the Golden Horde, Nogai Khan a direct descendant of Genghis Khan through Jochi, formed an army of the Manghits joined by numerous Turkic tribes. A century later the Nogais were led by Edigu, a commander of Manghit paternal origin and Jochid maternal origin, who founded the Nogai dynasty. In 1557 the Nogai Nur-al-Din Qazi Mirza quarreled with Ismael Beg and founded the Lesser Nogai Horde on the steppe of the North Caucasus. The Nogais north of the Caspian were thereafter called the Great Nogai Horde. In the early 17th century The Great Nogai Horde broke down further under the onslaught of the Kalmyks.
