A report on Xinjiang, Tarim Basin, Xiongnu and Silk Road

The Yuezhi were an ancient people first described in Chinese histories as nomadic pastoralists living in an arid grassland area in the western part of the modern Chinese province of Gansu, during the 1st millennium BC. After a major defeat at the hands of the Xiongnu in 176 BC, the Yuezhi split into two groups migrating in different directions: the Greater Yuezhi (Dà Yuèzhī 大月氏) and Lesser Yuezhi (Xiǎo Yuèzhī 小月氏).

The subsequent Kushan Empire, at its peak in the 3rd century AD, stretched from Turfan in the Tarim Basin in the north to Pataliputra on the Gangetic plain of India in the south.

The Kushanas played an important role in the development of trade on the Silk Road and the introduction of Buddhism to China.

They have thus placed the original homeland of the Yuezhi 1,000 km further northwest in the grasslands to the north of the Tian Shan (in the northern part of modern Xinjiang).

Kucha, or Kuche (also: Kuçar, Kuchar; كۇچار, Кучар; also ; कूचीन), 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.

The area lies in present-day Aksu Prefecture, Xinjiang, China; Kuqa town is the county seat of that prefecture's Kuqa County.

During the Later Han (25–220 CE), Kucha, with the whole Tarim Basin, became a focus of rivalry between the Xiong-nu to the north and the Chinese to the east.

The Tarim mummies are a series of mummies discovered in the Tarim Basin in present-day Xinjiang, China, which date from 1800 BC to the first centuries BC, with a new group of individuals recently dated to between c. 2100 and 1700 BC. The mummies, particularly the early ones, are frequently associated with the presence of the Indo-European Tocharian languages in the Tarim Basin, although the evidence is not totally conclusive and many centuries separate these mummies from the first attestation of the Tocharian languages in writing.

After the Yuezhi experienced a series of major defeats at the hands of the Xiongnu, during the 2nd century BCE, a group known as the Greater Yuezhi migrated to Bactria, where they established the Kushan Empire.

She was discovered in 1980 by Chinese archaeologists working on a film about the Silk Road.

From its numerous subjects, the dynasty raised professional and conscripted armies of hundreds of thousands of troops to contend with nomadic powers for control of Inner Asia and the lucrative trade-routes along the Silk Road.

While the Turks were settled in the Ordos region (former territory of the Xiongnu), the Tang government took on the military policy of dominating the central steppe.

There was a long string of conflicts with Tibet over territories in the Tarim Basin between 670 and 692, and in 763 the Tibetans even captured the capital of China, Chang'an, for fifteen days during the An Shi Rebellion.

In fact, it was during this rebellion that the Tang withdrew its western garrisons stationed in what is now Gansu and Qinghai, which the Tibetans then occupied along with the territory of what is now Xinjiang.

Central Asia was historically closely tied to the Silk Road trade routes, acting as a crossroads for the movement of people, goods, and ideas between Europe and the Far East.

The Russian geographer Nikolaĭ Khanykov questioned the latitudinal definition of Central Asia and preferred a physical one of all countries located in the region landlocked from water, including Afghanistan, Khorasan, Kyrgyzstan, Tajikistan, Turkmenistan, Uyghuristan (Xinjiang), and Uzbekistan.

Tocharian, another Indo-European language group, which was once predominant in oases on the northern edge of the Tarim Basin of Xinjiang, is now extinct.

Russian historian Lev Gumilev wrote that Xiongnu, Mongols (Mongol Empire, Zunghar Khanate) and Turkic peoples (First Turkic Khaganate, Uyghur Khaganate) played a role to stop Chinese aggression to the north.
