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.

From the 1250s to about 1300, the Golden Horde's kingmaker Nogai Khan (a direct descendant of Genghis Khan through Jochi) formed an army of the Manghits joined by numerous Turkic tribes. Around a century later in the 1390s, 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.

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. They were mostly Sunni Muslims, but their religious institutions were not centralised and the Nogais strongly opposed any efforts to do so. When the Ottomans tried to impose their control over the Nogai Horde, they heavilly supported the creation of new mosques and madrasses as they served as the instrument of political legitimisation for the Ottoman sultan who also served as the Caliph. However, those attempts were mostly unsuccessful and the Ottomans failed to demolish the authority of the tribe leaders and centralize their rule over the Nogais.

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 winter camp was at Saraychik, a caravan town on the lower Yaik. From 1537 the second in rank was the Nur-al-Din, usually the Bey's son or younger brother and expected successor. The Nur-al-Din held the right bank along the Volga. From the 1560s there was a second Nur-al-Din, a sort of a war chief. Third in rank was the Keikuvat, who held the Emba.
