Protectorate of the Western Regions

During the Han–Xiongnu War, the Chinese empire established a military garrison at Wulei (near present-day Cedaya 策达雅, in Bugur/Luntai County). The Chinese sought to control the Western Regions in order to keep the Xiongnu away from Inner China, and to control the valuable Silk Road trade that passed through the area. The local inhabitants of the Western Regions were diverse, and the area contained several groups who originated in Western Eurasia and/or spoke Indo-European languages. These groups included Tocharian-speaking city-states like Ārśi (Arshi; later Agni/Karasahr), Kuča (Kucha), Gumo (later Aksu), Turfan (Turpan), and Loulan (Krorän/Korla). Additionally, residents of the oasis city-states of Khotan and Kashgar spoke Saka, one of the Eastern Iranian languages.[4]

Prior to the establishment of the protectorate, there was a preceding post known as the "Colonel [for the Assistance of Imperial] Envoys" that was established a year after the War of the Heavenly Horses ended in 101 BC. After the war, Han posts were erected between Dunhuang and the Salt Marsh with several hundred farmer soldiers stationed at Luntai and Quli. The post was established to guard their farmland and to take care of grain storage for Han envoys traveling to other states.[5]

The position of Protector-General was officially established in 59 or 60 BCE after the Southern Xiongnu ruler Bi, the Rizhu King of the Right, submitted to the Han dynasty. Rizhu was bestowed the title of Marquis of Allegiance to Imperial Authority while Zheng Ji, the envoy who received him, was commissioned to act Protector-General of both the Northern and Southern routes. Another account states that the post of Protector-General had already been established by 64 BC and Zheng Ji was sent out to meet Rizhu, who led over 10,000 Xiongnu to submit to Han authority. Under the Protector-General was a Deputy Colonel of the Western Regions. The Protector-General established a general headquarters at Wulei.[5]

It was the highest Han dynasty military position in the west during its existence. During the peak of the Protectorate's power in 51 BCE, the Wusun nation was brought under Han submission.[3] The post was abandoned after the usurpation of Wang Mang (Xin dynasty) from 8-22 CE. By then, at least 18 different people had served as protector-general, though only 10 of them have known names. In 45 CE, the eighteen states of the Western Regions requested the re-establishment of the Protectorate to restore peace to the region, but Emperor Guangwu of Han refused.[6]

During the second half of the first century CE, at the time of the Eastern Han dynasty, Chinese armies led by Ban Chao, Dou Gu, and Guo Xun brought the Western Regions back under Han control. The Protectorate was thus re-established.[7] In 74 CE, Emperor Ming of Han and his successor awarded the position of Protector-General (now with administrative obligations as well) to general Chen Mu. In 83 CE, the office of Chief Official of the Western Regions was established and awarded to Ban Chao. The position of the Chief Official was beneath that of the Protector-General. Ban Chao would later be made Protector-General in 91 CE, after which he reconquered the Western Regions.[8] The seat of the Protectorate was for a time shifted to Taqian (or Tagan; near modern Kucha).[5] Ban Chao was succeeded by Ren Shang and Duan Xi.[6]

On 29 July 107, a series of Qiang uprisings in the areas of Hexi Corridor and Guanzhong. Duan Xi was killed and the post was abandoned. The Protectorate was later restored from 123-124 by the son of Ban Chao, Ban Yong. The Protectorate was again revived in 335 by Former Liang and headquartered in Gaochang until the demise of Northern Liang.[5]

In the southern Tarim Basin, coins from the period of the Protectorate's existence have been found with inscriptions in both Chinese and the Kharoshthi script, which was used for local Indo-European languages.[9]

In the 7th century, a successor administration, the Protectorate General to Pacify the West was established by the Tang Dynasty at Xizhou (Turpan) and was later moved to Kucha.[6]
