Year 644 (DCXLIV) was a leap year starting on Thursday of the Julian calendar. The denomination 644 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
The Tocharians, or Tokharians, were speakers of Tocharian languages, Indo-European languages known from around 7,600 documents from around 400 to 1200 AD, found on the northern edge of the Tarim Basin . The name "Tocharian" was given to these languages in the early 20th century by scholars who identified their speakers with a people known in ancient Greek sources as the Tókharoi, who inhabited Bactria from the 2nd century BC. This identification is generally considered erroneous, but the name "Tocharian" remains the most common term for the languages and their speakers. Their actual ethnic name is unknown, although they may have referred to themselves as Agni, Kuči, and Krorän, or Agniya, Kuchiya as known from Sanskrit texts.
Turpan is a prefecture-level city located in the east of the autonomous region of Xinjiang, China. It has an area of 69,759 square kilometres (26,934 sq mi) and a population of 693,988 (2020).
The Tarim Basin is an endorheic basin in Xinjiang, Northwestern China occupying an area of about 888,000 km2 (343,000 sq mi) and one of the largest basins in Northwest China. Located in China's Xinjiang region, it is sometimes used synonymously to refer to the southern half of the province, that is, Southern Xinjiang or Nanjiang, as opposed to the northern half of the province known as Dzungaria or Beijiang. Its northern boundary is the Tian Shan mountain range and its southern boundary is the Kunlun Mountains on the edge of the Tibetan Plateau. The Taklamakan Desert dominates much of the basin. The historical Uyghur name for the Tarim Basin is Altishahr, which means 'six cities' in Uyghur. The region was also called Little Bukhara or Little Bukharia.
Kucha, or Kuche, was an ancient Buddhist kingdom located on the branch of the Silk Road that ran along the northern edge of what is now the Taklamakan Desert in the Tarim Basin and south of the Muzat River.
Karasahr or Karashar, which was originally known in the Tocharian languages as Ārśi, Qarašähär, or Agni or the Chinese derivative Yanqi, is an ancient town on the Silk Road and the capital of Yanqi Hui Autonomous County in the Bayingolin Mongol Autonomous Prefecture, Xinjiang.
Gaochang, also called Khocho, Karakhoja, Qara-hoja, Kara-Khoja or Karahoja, was a ruined ancient oasis city on the northern rim of the inhospitable Taklamakan Desert in present-day Xinjiang, China. The site is also known in published reports as Chotscho, Khocho, Qocho or Qočo. During the Yuan dynasty and Ming dynasty, Gaochang was referred to as "Halahezhuo" (Qara-khoja) and Huozhou.
The Protectorate of the Western Regions (simplified Chinese: 西域都护府; traditional Chinese: 西域都護府; pinyin: Xīyù Dūhù Fǔ; Wade–Giles: Hsi1-yü4 Tu1-hu4 Fu3) was an imperial administration (a protectorate) situated in the Western Regions administered by Han dynasty China and its successors on and off from 59 or 60 BCE until the end of the Sixteen Kingdoms period in 439. The "Western Regions" refers to areas west of Yumen Pass, especially the Tarim Basin in southern Xinjiang. These areas would later be termed Altishahr (southern Xinjiang, excluding Dzungaria) by Turkic-speaking peoples. The term "western regions" was also used by the Chinese more generally to refer to Central Asia.
The Protectorate General to Pacify the West, initially the Protectorate to Pacify the West, was a protectorate established by the Chinese Tang dynasty in 640 to control the Tarim Basin. The head office was first established at the prefecture of Xi, now known as Turpan, but was later shifted to Qiuci (Kucha) and situated there for most of the period.
In the years following Tang Taizong's subjugation of the Eastern Turkic Khaganate, the emperor began to exert his military power toward the oasis city-states of the Tarim Basin. These states, populated by Tocharian and Saka peoples, were loosely allied with the Western Turkic Khaganate. In 640, Emperor Taizong sent the military commander Hou Junji to defeat and annex Gaochang (Karakhoja)—the first attempt by any Chinese dynasty to set up a permanent military and political presence in the region since Fu Jian in the 4th century. In 644, after Karasahr (Yanqi)—an ally in the campaign against Karakhoja—turned against Tang and allied with the Western Turkic Khaganate, the Tang commandant at Karakhoja, Guo Xiaoke, attacked and captured the King of Karasahr, Long Tuqizhi, but Karasahr subsequently rebelled. In 648, the ethnically Turkic Tang general Ashina She'er who was the second son of Shibi Khan, attacked both Karasahr and Kucha in the northern Tarim, conquering both. Kashgar and Khotan in the western Tarim then also submitted to Tang, allowing the dynasty to dominate the region until it was briefly seized by Tibet during the reign of Emperor Taizong's son Emperor Gaozong.
The Four Garrisons of Anxi were Chinese military garrisons installed by the Tang dynasty in the Tarim Basin between 648 and 658. They were stationed at the Indo-European city-states of Qiuci (Kucha), Yutian (Hotan), Shule (Kashgar) and Yanqi (Karashahr) in modern Xinjiang. The Protectorate General to Pacify the West was headquartered in Qiuci.
The Tang dynasty in Inner Asia was the expansion of the Tang dynasty's realm in Inner Asia in the 7th and, to a lesser degree, the 8th century AD, in the Tarim Basin, the Mongolian Plateau, and portions of Central Asia. Wars were fought against the Gokturk Empires and Xueyantuo, but also against many states of Central Asia. This expansion was not steady; for example, the Tang did lose control of the Tarim Basin temporarily to the Tibetan Empire in the 680s, and their expansion north of the Gobi Desert was thwarted in 682. Emperor Taizong's military success was, in part, a consequence of changes he initiated in the Chinese army, including improved weaponry. The emperor placed a new emphasis on cavalry, which was very important because his non-Han opponents used the horse effectively in warfare.
The Shorchuk or Shikshin Temple is a ruined compound of Buddhist sites located about 25–30 km southwest of the town of Karasahr, Yanqi Hui Autonomous County, Xinjiang, China. The site was a major religious center along the northern route of the Silk Road in the second half of the first millennium CE. Another name for the site is Ming-oi in Turkic.
The conquest of the Western Turks, known as the Western Tujue in Chinese sources, was a military campaign in 655–657 led by the Tang dynasty generals Su Dingfang and Cheng Zhijie against the Western Turkic Khaganate ruled by Ashina Helu. The Tang campaigns against the Western Turks began in 640 with the annexation of the Tarim Basin oasis state Gaochang, an ally of the Western Turks. Several of the oasis states had once been vassals of the Tang dynasty, but switched their allegiance to the Western Turks when they grew suspicious of the military ambitions of the Tang. Tang expansion into Central Asia continued with the conquest of Karasahr in 644 and Kucha in 648. Cheng Zhijie commanded the first foray against the West Tujue, and in 657 Su Dingfang commanded the main army dispatched against the Western Turks, while the Turkic generals Ashina Mishe and Ashina Buzhen led the side divisions. The Tang troops were reinforced by cavalry supplied by the Uyghurs, a tribe that had been allied with the Tang since their support for the Uyghur revolt against the Xueyantuo. Su Dingfang's army defeated Helu at the battle of Irtysh River.
The Tang campaign against Kucha was a military campaign led by the Tang dynasty general Ashina She'er against the Tarim Basin oasis state of Kucha in Xinjiang, which was aligned with the Western Turkic Khaganate. The campaign began in 648 and ended on 19 January 649, after the surrender of the Kuchan forces following a forty-day siege in Aksu. Kuchean soldiers tried to recapture the kingdom with the assistance of the Western Turkic Khaganate, but were defeated by the Tang army.
The Tang campaigns against the Western Turks, known as the Western Tujue in Chinese sources, were a series of military campaigns conducted by the Tang dynasty against the Western Turkic Khaganate in the 7th century AD. Early military conflicts were a result of the Tang interventions in the rivalry between the Western and Eastern Turks in order to weaken both. Under Emperor Taizong, campaigns were dispatched in the Western Regions against Gaochang in 640, Karasahr in 644 and 648, and Kucha in 648.
The Tang campaigns against Karasahr were two military campaigns sent by Emperor Taizong of the Tang dynasty against the Tarim Basin kingdom of Karasahr, a vassal of the Western Turkic Khaganate. The city-state, which later became part of Xinjiang), may have been known to its inhabitants by the Tocharian name Agni, which was rendered Yanqi in Chinese sources. The first campaign in 644 was led by the Tang commander Guo Xiaoke, protector-general of the Anxi Protectorate in western China, who defeated the oasis state and a Western Turkic army and installed a Tang loyalist as ruler. The second campaign in 648, which was part of the campaign against Karasahr's neighboring state of Kucha, was led by a Turkic general of the Tang dynasty, Ashina She'er, who defeated and conquered Karasahr.
The military of the Tang dynasty was staffed with a large population of Turkic soldiers, referred to as Tujue (突厥) in Chinese sources. Tang elites in northern China were familiar with Turkic culture, a factor that contributed to the Tang acceptance of Turkic recruits. The Tang emperor Taizong adopted the title of "Heavenly Kaghan" and promoted a cosmopolitan empire. Turkic soldiers that served under the Tang dynasty originated from the Eastern Turkic Khaganate. It began with Tang dynasty Emperor Taizong who sent his general Li Jing, eventually ended in defeating the Eastern Turks and capturing their leader Jiali Khan.
Turkic peoples began settling in the Tarim Basin in the 7th century. The first settlers were likely Tang-allied Türk (Tujue) tribes. The area was later settled by the Uyghur people, who founded the Qocho Kingdom there in the 9th century. The historical area of what is modern-day Xinjiang consisted of the distinct areas of the Tarim Basin and Dzungaria. The area was first populated by Indo-European Tocharian and Saka peoples, who practiced Buddhism. The Tocharian and Saka peoples came under Chinese rule in the Han dynasty as the Protectorate of the Western Regions due to wars between the Han dynasty and the Xiongnu and again in the Tang dynasty as the Protectorate General to Pacify the West due to wars between the Tang dynasty and the First, Western, and Eastern Turkic Khaganates. The Tang dynasty withdrew its control of the region in the Protectorate General to Pacify the West and the Four Garrisons of Anxi after the An Lushan Rebellion, after which the Turkic peoples and the other native inhabitants living in the area gradually converted to Islam.
The Shule Kingdom was an ancient oasis kingdom of the Taklamakan Desert that was on the Northern Silk Road, in the historical Western Regions of what is now Xinjiang in Northwest China. Its capital was Kashgar, the source of Kashgar's water being a river of the same name. Much like the neighboring people of the Kingdom of Khotan, people of Kashgar spoke Saka, one of the Eastern Iranian languages.
