Dalai Lama in the context of "1959 Tibetan uprising"

While the Tibetan Plateau has been inhabited since pre-historic times, most of Tibet's history went unrecorded until the creation of Tibetan script in the 7th century. Tibetan texts refer to the kingdom of Zhangzhung (c. 500 BCE – 625 CE) as the precursor of later Tibetan kingdoms and the originators of the Bon religion. While mythical accounts of early rulers of the Yarlung dynasty exist, historical accounts begin with the introduction of Tibetan script from the unified Tibetan Empire in the 7th century. Following the dissolution of Tibetan Empire and a period of fragmentation in the 9th–10th centuries, a Buddhist revival in the 10th–12th centuries saw the development of three of the four major schools of Tibetan Buddhism.

After a period of control by the Mongol Empire and the also Mongol led Yuan dynasty, Tibet effectively became independent in the 14th century and was ruled by a succession of noble houses for the next 300 years. In the 16th century, the Dalai Lama title was created by Altan Khan, and as requested by the family of Altan Khan, seal of authority was granted to the Dalai Lama by the Wanli Emperor. In the 17th century, the senior lama of the Gelug school, the Dalai Lama, became the head of state with the aid of the Khoshut Khanate. Seal of authority and golden sheets were granted by the Shunzhi Emperor to both the Dalai Lama and the founder Güshi Khan of Khoshut Khanate in 1653. In 1717, the Dzungar Khanate invaded Lhasa, killed Lha-bzang Khan of the Khoshut Khanate, which effectively destroyed the Khoshut Khanate. The Qing dynasty then sent military troops in the same year to fight the Dzungars, but failed.

Tibetan Buddhism is a form of Buddhism practiced in Tibet, Bhutan and Mongolia. It also has a sizable number of adherents in the areas surrounding the Himalayas, including the Indian regions of Ladakh, Darjeeling, Sikkim, and Arunachal Pradesh, as well as in Nepal. Smaller groups of practitioners can be found in Central Asia, some regions of China such as Northeast China, Xinjiang, Inner Mongolia and some regions of Russia, such as Tuva, Buryatia, and Kalmykia.

Tibetan Buddhism evolved as a form of Mahayana Buddhism stemming from the latest stages of Buddhism (which included many Vajrayana elements). It thus preserves many Indian Buddhist tantric practices of the post-Gupta early medieval period (500–1200 CE), along with numerous native Tibetan developments. In the pre-modern era, Tibetan Buddhism spread outside of Tibet primarily due to the influence of the Mongol-led Yuan dynasty, founded by Kublai Khan, who ruled China, Mongolia, and parts of Siberia. In the Modern era, Tibetan Buddhism has spread outside of Asia because of the efforts of the Tibetan diaspora (1959 onwards). As the Dalai Lama escaped to India, the Indian subcontinent is also known for its renaissance of Tibetan Buddhism monasteries, including the rebuilding of the three major monasteries of the Gelug tradition.

The Gelug (/ɡəˈluːɡ/, also Geluk; lit. 'virtuous') is the youngest of the four major schools of Tibetan Buddhism. It was founded by Je Tsongkhapa (1357–1419), a Tibetan philosopher, tantric yogi and lama and further expanded and developed by his disciples (such as Khedrup Je, Gyaltsap Je, Dulzin Drakpa Gyaltsen, and Gendün Drubpa).

The Gelug school is alternatively known as Kadam (bKa’-gdams gsar-pa), since it sees itself as a continuation of the Kadam tradition of Atisha (c. 11th century). The school of New Kadam, or New Kadampa is an offshoot of the Gelug-tradition. Furthermore, it is also called the Ganden school, after the first monastery established by Tsongkhapa. The Ganden Tripa ("Ganden Throne Holder") is the official head of the school, though its most influential political figure is the Dalai Lama ("Ocean Teacher"). Allying themselves with the Mongol Khans, the Gelug school emerged as the dominant Buddhist school in Tibet and Mongolia since the end of the 16th century (religiously and politically). Another alternative name for this tradition is the Yellow Hat school or sect.

The Khoshut Khanate was a Mongol Oirat khanate based in the Tibetan Plateau from 1642 to 1717. Based in modern Qinghai, it was founded by Güshi Khan in 1642 after defeating the opponents of the Gelug school of Tibetan Buddhism in Tibet. The 5th Dalai Lama established a civil administration known as Ganden Phodrang with the aid of Güshi Khan. The role of the khanate in the affairs of Tibet has been subject to various interpretations. Some sources claim that the Khoshut did not interfere in Tibetan affairs and had a priest and patron relationship between the khan and Dalai Lama while others claim that Güshi appointed a minister, Sonam Rapten, as de facto administrator of civil affairs while the Dalai Lama was only responsible for religious matters. Güshi Khan accepted the nominal suzerainty of the Qing dynasty in 1654, when seal of authority and golden sheets were granted by the Shunzhi Emperor. In the last years of the khanate, Lha-bzang Khan murdered the Tibetan regent and deposed the 6th Dalai Lama in favor of a pretender Dalai Lama.

The Khoshut Khanate was ended in 1717 when the Dzungar prince Tseren Dondup invaded Tibet, killed Lha-bzang Khan, and installed the 7th Dalai Lama.

Güshi Khan (1582 – 14 January 1655) was a Khoshut prince and founder of the Khoshut Khanate, who supplanted the Tumed descendants of Altan Khan as the main benefactor of the Dalai Lama and the Gelug school of Tibetan Buddhism. In 1637, Güshi Khan defeated a rival Mongol prince Choghtu Khong Tayiji, a Kagyu follower, near Qinghai Lake and established his khanate in Tibet over the next years. His military assistance to the Gelug school enabled the 5th Dalai Lama to establish political control over Tibet.

The Dzungar Khanate (Mongolian: ᠵᠡᠭᠦᠨᠭᠠᠷ ᠣᠯᠣᠰ Зүүнгар Улс), also known as the Zunghar Khanate or Junggar Khanate, was a nomadic khanate of Oirat Mongol origin. At its greatest extent, it covered an area from southern Siberia in the north to present-day Kyrgyzstan in the south, and from present-day west of Mongolia and the Great Wall of China in the east to present-day Kazakhstan in the west. The core of the Dzungar Khanate is today part of northern Xinjiang, also called Dzungaria.

About 1620 the western Mongols, known as the Oirats, united in the Junggar Basin in Dzungaria. In 1678, Galdan received from the Dalai Lama the title of Boshogtu Khan, making the Dzungars the leading tribe within the Oirats. The Dzungar rulers used the title of Khong Tayiji, which translates into English as "crown prince". Between 1680 and 1688, the Dzungars conquered the Tarim Basin, which is now southern Xinjiang, and defeated the Khalkha Mongols to the east. In 1696, Galdan was defeated by the Qing dynasty and lost Outer Mongolia. In 1717, the Dzungars conquered Tibet, but were driven out in 1720 by the Qing. From 1755 to 1758, Qing China took advantage of a Dzungar civil war to conquer Dzungaria and killed 70–80% of the Dzungar population. The destruction of the Dzungars led to the Qing conquest of Mongolia, Tibet, and the creation of Xinjiang as a political administrative unit.

Lha-bzang Khan (Mongolian: ᠯᠠᠽᠠᠩ ᠬᠠᠭᠠᠨ Lazang Khaan; Tibetan: ལྷ་བཟང༌, ZWPY: Lhasang; alternatively, Lhazang or Lapsangn or Lajang; d.1717) was the ruler of the Khoshut (also spelled Qoshot, Qośot, or Qosot) tribe of the Oirats. He was the son of Tenzin Dalai Khan (1668–1701) and grandson (or great-grandson) of Güshi Khan, being the last khan of the Khoshut Khanate and Oirat King of Tibet. He acquired effective power as ruler of Tibet by eliminating the regent (desi) Sangye Gyatso and the Sixth Dalai Lama, Tsangyang Gyatso, but his rule was cut short by an invasion by another group of Oirats, the Dzungar people. At length, this led to the direct involvement of the Chinese Qing dynasty in the Tibetan politics.
