In
The Secret History of the Mongols, the Naiman subtribe the "Güchügüd" are mentioned. According to Russian Turkologist
Nikolai Aristov's view, the Naiman Khanate's western border reached the
Irtysh River and its eastern border reached the Mongolian
Tamir River. The
Altai Mountains and southern
Altai Republic were part of the Naiman Khanate. They had diplomatic relations with the
Kara-Khitans, and were subservient to them until 1175. Western European and Asian scholars classified them as a
Turkic people from
Sekiz Oghuz (means "Eight Oghuz" in
Turkic). Scholars like Paul Ratchnevsky, Hans Robert Roemer,
Steven Runciman,
John Man,
Morris Rossabi,
Frederick W. Mote, Li Tang, Joo-Yup Lee/Shuntu Kuang, Hans-Joachim Klimkeit, For instance, such Russian orientalists as
Vasily Bartold, Vadim Trepavlov classified them as one of Mongol tribes. They have been described as Turkic-speaking, Chinese historian Feng Chia-Sheng considered the Naimans to be the western branch of the
Zubu; in his view, the eastern Zubu were the Jalairs and the Tatars, while the northern Zubu were the Keraites. Like the
Khitans and the
Uyghurs, many of them were
Nestorian Christians or
Buddhists. The Naimans were located to the west of the Mongols, and there were more Naimans than Mongols in the late 12th century. In 1199, Temüjin (
Genghis Khan) together with an ally
Ong khan launched a campaign against the Naimans. They defeated Buyirugh, a Naiman khan who ruled the mountain lineage. In 1203, the last
Tayang khan, the ruler of Naimans of the steppe, was killed after a battle with Genghis Khan. His son
Kuchlug with his remaining Naiman troops then fled to the
Kara-Khitan Khanate. Kuchlug was well received there and the Khitan Khan gave him his daughter in marriage. Kuchlug soon began plotting against his new father-in-law, and after he usurped the throne, he began to persecute Muslims in the
Hami Oases. But his action was opposed by local people and he was later defeated by the Mongols under
Jebe. Although the Naiman Khanlig was crushed by the Mongols, they were seen in every part of the
Mongol Empire.
Ogedei's great
khatun ("queen")
Töregene might have been from this tribe.
Hulegu had a Naiman general,
Ketbuqa, who died in the
Battle of Ain Jalut in 1260. After the collapse of the Yuan dynasty, the Naiman were eventually assimilated into Mongol, Tatar, and Kazakh tribes. == Among Mongols ==
