The earliest is the alleged plot to invade Tibet by Genghis Khan in 1206, which is considered anachronistic; there is no evidence of Mongol-Tibetan encounters prior to the military campaign in 1240.
These relations were continued by Kublai Khan, who founded the Mongol Yuan dynasty and granted authority over whole Tibet to Drogon Chogyal Phagpa, nephew of Sakya Pandita.
[2] Genghis' campaign was targeted at the Tangut kingdom of Western Xia, not Tibet, and there was certainly no tribute being paid to the Mongols prior to 1240.
In 1240, the Mongol Prince Godan, Ögedei's son and Güyük's younger brother, "delegated the command of the Tibetan invasion to the Tangut[5] general, Doorda Darqan (Dor-ta)".
[11] However, modern studies find that the oldest sources credit the Mongol scouts with burning Rgyal-lha-khang only, while a large number of Rwa-sgreng monks were slain.
[7] Wylie points out that the Tibetans stopped paying tribute in 1227, while Doorda Darkhan's invasion was in 1240, suggesting that the Mongols, not known for their empathy, would not wait over a decade to respond.
The text from which this claim is based on also makes other anachronistic mistakes, insisting that Genghis was planning to attack Tibet prior to Doorda Darkhan's invasion, when the real campaign was against the Tangut kingdom of Western Xia.
[16] The Mongols hoped to find a single monarch with whom they could threaten into submission, but instead found a Tibet that was religiously and politically divided, without a central government.
They invited Sakya Pandita to Godan's camp, where he agreed to capitulate Tibet, after the Mongols threatened a full-scale invasion of the region.
In order to strengthen his control over Tibet, Möngke made Qoridai commander of the Mongol and Han troops in Turpan in 1251.
Wyle is sceptical however of all of these sources, arguing that the lack of substantive evidence for an invasion raises doubts about the extent of Mongol movements in Tibet proper.
'[21] He concludes:- "Excluding the 1252 attack against the unidentified Mon-mkmar-mgon-po-gdong mentioned earlier, there seems to be no evidence to prove the presence of Mongol troops in central Tibet during the two decades that 'Phags-pa Lama was away from Sa-skya (1244–65).
During those years, external campaigns of conquest and internal feuds between scions of the sons of Chinggis Khan occupied the attention of the Mongols.
Later William Rubruck reports that he saw Chinese, Tibetan, and Indian Buddhist monks at the capital city, Karakorum, of the Mongol Empire.
Although, Karmapa of the Karma Kagyu school politely refused to stay with him, preferring his brother the Khagan, in 1253 Prince Kubilai summoned to his court the Sa-skya-pa hierarch's two nephews, Blo-gros rGyal-mtshan, known as ’Phags-Pa lama (1235–80), and Phyag-na rDo-rje (1239–67) from the late Godan's ordo in Liangzhou.
Tibet was subdued to the Mongol Empire under Mongolian administrative rule,[25] but the region was granted with a degree of political autonomy.
[28] Though most government institutions established by Kublai Khan in his court resembled the ones in earlier Chinese dynasties,[29] Tibet never adopted the imperial examinations or Neo-Confucian policies.
Buddhist monks from Tibet were popular and well respected in Mongol-ruled Iran (the Ilkhanate),[24] Mongolia, China (the Yuan) and Central Asia (the Chagatai Khanate).
[citation needed] by support The Oirats converted to Tibetan Buddhism around 1615, and it was not long before they became involved in the conflict between the Gelug and Karma Kagyu schools.
The descendants of Güshi Khan continued to rule as Dharma kings (chogyals) of Tibet, although they were eclipsed by the Dalai Lama and his regent for long periods.
The Emperor retaliated in 1718, but his military expedition suffered inadequate logistics and was annihilated by the Dzungars at the Battle of the Salween River not far from Lhasa.
[33] In 1723 Lobzang Danjin, another descendant of Güshi Khan, defended Amdo against Qing dynasty's attempts to extend its rule into Tibet, but was crushed in the following year.
