The Four Oirat (Dorben Oirad), also known as the Alliance of the Four Oirat tribes or the Oirat confederation (Oirads; Mongolian: ; in the past, also Eleuths), was the confederation of the Oirat tribes, which marked the rise of the Western Mongols in Mongolian history.
Despite the universal currency of the term "Four Oirat" among Eastern Mongols and Oirats and numerous explanations by historians, no consensus has been reached on the identity of the original four tribes. While it is believed that the term Four Oirats refers to the Choros, Torghut, Dorbet and Khoid tribes, there is a theory that the Oirats were not consanguineous units but political-ethnic units, composed of many patrilineages.
After the overthrow of the Yuan dynasty (1271-1368), Möngke-Temür, a high official of the Yuan, had placed himself at the head of the Oirats. When he died, three chieftains, Mahamu (Mahmud), Taiping and Batu-bolad, ruled them. They sent envoys with gifts to the Ming dynasty. In 1409, the Yongle Emperor (r. 1402-1424) bestowed upon them the title of wang in return. The Oirats began to challenge the Borjigin Emperors in the reign of Elbeg Khan (c. 1394-1399).
It is curious to find one of the 3 chief was with Muslim name, Mahmud. Before 1640, the Oirats had been wavering between the two faiths, Islam and Buddhism. Both these creeds had supporters among the pagan Oirats.
The Chinese Yongle Emperor demanded Öljei Temür Khan Bunyashiri to accept his supremacy in 1409 but Öljei Temür refused and defeated a Ming force the next year. In 1412 a large force under Yongle forced Öljei Temür Khan to flee westward. The Oirats led by Mahamu of Choros killed Öljei Temür who suffered great loss.
The Western Mongols had Delbeg Khan, a descendant of Ariq Böke, whose family had been relegated to Mongolia during the Yuan, crowned. However, the Eastern Mongols under Arugtai of the Asud refused to accept the new khan and they were in constant war with each other. The Ming dynasty intervened aggressively against any overpowerful Mongol leader, exacerbating the Mongol-Oirat conflict.
In 1408 Mahamu was succeeded by his son Toghan, who continued his strife with Arugtai chingsang. By 1437, Toghan had totally defeated Arugtai and an Ögedeid Emperor Adai Khan. Toghan made Genghisid princes his puppet khans of the Mongolia-based Northern Yuan dynasty. When he died in 1438, his son Esen became a taishi. The Oirats had close relations with Moghulistan and Hami where the Chagatayid Khans reigned. From the Ming chronicles, it is known that the Oirats conducted regular raids on those areas. Esen crushed the Moghulistan and Hami monarchs and forced them to accept him as their overlord. He also conquered Outer and Inner Mongolia and subjugated the Jurchens in Manchuria. The Ming's Zhengtong Emperor was captured by Esen in 1449. During his reign, the Oirat headquarters was centered on north-west Mongolia and Barkol and the Irtysh were the western limits of their settlement. Esen relied on Muslim merchants from Samarkand, Hami and Turpan and his own royal house: Choros was related to Moghulistan according to a myth. After murdering Khagan Agbarjin, Esen took the title khan for himself. But soon after he was overthrown by the Oirat noblemen and killed by a son of a man whom he executed.
From 1480 on, the Eastern Mongols under Mandukhai Khatun and Dayan Khan pushed the Oirats westward. By 1510 Dayan Khan had unified the entire Mongol nation including Oirats. However, the Khalkhas and some princes of southwest Inner Mongolia repeatedly launched massive attacks on the Oirats and looted their properties in the Irtysh, Barkol and Altai from 1552 to 1628. The Oirats were still powerful in Mongolia even after the fall of Esen and continued to hold Karakorum until the 16th century when Altan Khan recaptured the city from the hands of the Oirats. Oppressed and subjugated by Altan Khan of the Khalkha, Oirat confederation crushed the Khalkha prince Sholoi Ubaashi Khungtaiji perhaps around 1623.
The collapse of the confederation of the Oirats began with Torghuds, along with the Dorbets and a few Khoshud clansmen, seceding from the union. In 1628 the Torghud chief Khoo Orlug with some Dorbeds and Khoshuuds moved westward across the Kazakh steppes. The little jüz of the Kazakhs and the Nogais tried to halt them at Nemba and Astrakhan but were defeated by the Torghuds. The Torghuds subjugated local Turkic peoples of Manghyslak and Caspian Sea. They colonized the Volga Delta and occupied whole steppes north of the Caspian, establishing the Kalmyk Khanate. The Kalmyks plundered the Khanate of Khiva from 1603 to 1670. The Kalmyk Khanate proved good allies to the Russian Empire.
The Khoshuud Güshi Khan went to Qinghai (Koke Nuur) in 1636. He increased his possessions in Tibet and Amdo. Güshi Khan protected the 5th Dalai Lama and his Yellow Church from the old red clergy of the Tibetan Buddhism. The Khoshut Khanate defeated the enemy of the Dalai Lama and Güshi Khan appointed his son ruler of Tibet.
About 1620 the Choros scattered after bitter fighting with the Khalkha Altan Khan. Some of the Choros fled with a body of the Dorbed northwad into Siberia and present-day Baranaoul. But the majority of the Choros with the Dorbeds and the Khoids settled in the region of the Black Irtysh, the Urungu, the Imil, and the Ili, forming the Dzungar Khanate.
In 1640 the Oirats and the Khalkha made peace and formed an alliance, issuing new code, the Mongol-Oirat code. Led by the Khoshuud nobility, the Oirats began to convert to Buddhism. They became the chief defenders of the Dalai and Panchen Lamas. The Oirats who used the Mongolian script adopted in 1648-49 the clear script designed by the Oirat cleric and scholar Zaya Pandita Namkhaijamtsu.
