The Nogai Horde was a confederation founded by the Nogais 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 Manghuds 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 Nogays were led by Edigu, a commander of Manghit paternal origin and Jochid maternal origin, who founded the Nogai dynasty. In 1557, 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 Horde broke down further under the onslaught of the Kalmyks. The Nogais north of the Black Sea were nominally subject to the Crimean Khanate rather than the Nogai Bey. They were divided into the following groups: Budjak (from the Danube to the Dniester), Yedisan (from the Dniester to the Bug), Jamboyluk (Bug to Crimea), Yedickul (north of Crimea) and Kuban. In particular, the Yedisans are mentioned as a distinct group, and in various locations. Society There were two groups of Nogais: those north of the Caspian Sea under their own Bey (leader), and those north of the Black Sea nominally subject to the Crimean Khan. The first group was broken up circa 1632 by the Kalmyks. The second shared the fate of the Khanate of Crimea. The Nogai language was a form of Kypchak Turkic, the same language group as that of the neighboring Kazakhs, Bashkirs and Crimean and Volga Tatars. Their religion was Muslim, but religious institutions were weakly developed. They were pastoral nomads grazing sheep, horses, and camels. Outside goods were obtained by trade (mostly horses and slaves), raiding, and tribute. There were some subject peasants along the Yaik river. One of the main sources of income for the Nogais was raiding for slaves, who were sold in Crimea and Bukhara. Hunting, fishing, caravan taxation, and seasonal agricultural migration also played a role, although this is poorly documented. The basic social unit was the semi-autonomous ulus or band. Aristocrats were called mirza. The ruler of the Nogais was the Bey. The capital or
