Chinese Turkestan in the context of "Gilgit Agency"

Inner Asia refers to the northern and landlocked regions spanning North, Central, and East Asia. It includes parts of western and northeast China, as well as southern Siberia. The area overlaps with some definitions of "Central Asia", mostly the historical ones, but certain regions that are often included in Inner Asia, such as Manchuria, are not a part of Central Asia by any of its definitions. Inner Asia may be regarded as the western and northern "frontier" of China proper and as being bounded by East Asia proper, which consists of China proper, Japan, and Korea.

The extent of Inner Asia has been understood differently in different periods. "Inner Asia" is sometimes contrasted to "China proper", that is, the territories originally unified under the Qin dynasty with majority Han populations. By the year 1800, Chinese Inner Asia consisted of four main areas, namely Manchuria (modern Northeast China and Outer Manchuria), the Mongolian Plateau (Inner Mongolia and Outer Mongolia), Xinjiang (Chinese Turkestan or East Turkestan), and Tibet. Many of these areas had been only recently conquered by the Qing dynasty of China and, during most of the Qing period, they were governed through administrative structures different from those of the older Chinese provinces. A Qing government agency, the Lifan Yuan, supervised the empire's Inner Asian regions, also known as Chinese Tartary. The frontier regions of China proper—Gansu, Qinghai, Sichuan, and Yunnan—are also sometimes included as part of Inner Asia.

East Turkestan or East Turkistan (Uyghur: شەرقىي تۈركىستان, ULY: Sherqiy Türkistan, UKY: Шәрқий Туркистан) is a loosely defined geographical region in the northwestern part of the People's Republic of China, on the cross roads of East and Central Asia. The term was coined in the 19th century by Russian Turkologists, including Nikita Bichurin, who intended the name to replace the common Western term for the region, "Chinese Turkestan", which referred to the Tarim Basin in Southern Xinjiang. Beginning in the 17th century, Altishahr, which means "Six Cities" in Uyghur, became the Uyghur name for the Tarim Basin. Uyghurs also called the Tarim Basin "Yettishar," which means "Seven Cities," and even "Sekkizshahr", which means "Eight Cities" in Uyghur. Chinese dynasties from the Han dynasty to the Tang dynasty had called an overlapping area the "Western Regions".

Starting in the 20th century, the Turkic Muslim Uyghur separatists and their supporters used East Turkestan as an appellation for the whole of Xinjiang (the Tarim Basin and Dzungaria) or for a future independent state in present-day Xinjiang Uyghur Autonomous Region. They reject the name Xinjiang (meaning "New Frontier" in Chinese) because of the Chinese perspective reflected in the name, and prefer East Turkestan to emphasize the connection to other, western Turkic groups.

Xinjiang, officially the Xinjiang Uygur Autonomous Region (XUAR), is an autonomous region of the People's Republic of China (PRC), in the northwest of the country at the crossroads of Central Asia and East Asia. The largest province-level division of China by area and the 8th-largest country subdivision in the world, Xinjiang spans over 1.6 million square kilometres (620,000 sq mi) and has about 25 million inhabitants. Xinjiang borders the countries of Afghanistan, India, Kazakhstan, Kyrgyzstan, Mongolia, Pakistan, Russia, and Tajikistan. The rugged Karakoram, Kunlun, and Tian Shan mountain ranges occupy much of Xinjiang's borders, as well as its western and southern regions. The Aksai Chin and Trans-Karakoram Tract regions are claimed by India but administered by China. Xinjiang also borders the Tibet Autonomous Region and the provinces of Gansu and Qinghai. The best-known route of the historic Silk Road ran through the territory from the east to its northwestern border.

High mountain ranges divide Xinjiang into the Dzungarian Basin (Dzungaria) in the north and the Tarim Basin in the south. Only about 9.7% of Xinjiang's land area is fit for human habitation. It is home to a number of ethnic groups, including the Han Chinese, Hui, Kazakhs, Kyrgyz, Mongols, Russians, Sibe, Tajiks (Pamiris), Tibetans, and Uyghurs. There are more than a dozen autonomous prefectures and counties for minorities in Xinjiang. Many older English-language reference works call the area Chinese Turkestan, Chinese Turkistan, East Turkestan or East Turkistan.

Chinese Tartary (Chinese: 中國韃靼利亞; pinyin: Zhōngguó Dádálìyà or Chinese: 中属鞑靼利亚; pinyin: Zhōng shǔ Dádálìyà) is an archaic geographical term referring to the regions of Manchuria, Mongolia, Xinjiang (also referred to as Chinese Turkestan), and Tibet under the rule of the Qing dynasty of China. The geographical extent of Chinese Tartary largely corresponds with that of the "Feudatory Regions" (Chinese: 藩部; pinyin: fānbù), as defined by the Qing court. The term "Tartar" was used by Europeans to refer to ethnicities living in northern, northeastern, and western China, including the Mongols, Manchus, Tibetans, and Central Asians. Some definitions include the Japanese (as indicated in violet on the map below). The regions are now more commonly referred to by scholars as Inner Asia.

Abū Ḥafṣ Qutayba ibn Abī Ṣāliḥ Muslim ibn ʿAmr al-Bāhilī (Arabic: أبو حفص قتيبة بن أبي صالح مسلم بن عمرو الباهلي; 669–715/6) was an Arab commander of the Umayyad Caliphate who became governor of Khurasan and distinguished himself in the conquest of Transoxiana during the reign of al-Walid I (705–715). A capable soldier and administrator, he consolidated Muslim rule in the area and expanded the Caliphate's border to include most of Transoxiana. From 705 to c. 710, he consolidated Muslim control over the native principalities of Tokharistan and conquered the principality of Bukhara, while in 710–712 he conquered Khwarizm and completed the conquest of Sogdiana with the capture of Samarkand. The latter opened the road to the Jaxartes valley, and during the last years of his life Qutayba led annual campaigns there, extending Muslim control up to the Fergana Valley and parts of Chinese Turkestan.

To increase his strained manpower, Qutayba initiated the wide-scale levy of native Khurasani and Transoxianian soldiers who fought alongside the Arab Muslim troops. Following Walid's death, Qutayba, insecure of his position under the new regime, rebelled but failed to secure the support of his army, and was killed. Most of his conquests in Transoxiana were lost in the years after his death; only in the 740s was the Muslim position restored to the line reached by Qutayba, and only after the Battle of Talas in 751 did the region come solidly under Muslim control.
