Altishahr in the context of "Uyghur language"

The Tarim Basin is an endorheic basin in Xinjiang, Northwestern China occupying an area of about 888,000 km (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 (Chinese: 南疆; pinyin: Nánjiāng), 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 (Traditional Uyghur: آلتی شهر, Chinese: 六城), which means 'six cities' in Uyghur. The region was also called Little Bukhara or Little Bukharia. The basin is a major area for renewable energy development, particularly solar and wind power, with a focus on utilizing the vast Taklamakan Desert. A high-voltage power loop has been constructed around the basin, collecting energy from various sources and transmitting it to other regions.

The Western Regions or Xiyu (Hsi-yü; Chinese: 西域) was a historical name specified in Ancient Chinese chronicles between the 3rd century BC to the 8th century AD that referred to the regions west of the Yumen Pass, most often the Tarim Basin in present-day southern Xinjiang (also known as Altishahr) and Central Asia (specifically the easternmost portion around the Ferghana Valley), though it was sometimes used more generally to refer to other regions to the west of China as well, such as Parthia (which technically belonged to West Asia) and Tianzhu (as in the novel Journey to the West, which refers to the Indian subcontinent in South Asia).

Because of their strategic location astride the Silk Road, the Western Regions have been historically significant to China since at least the 3rd century BC.

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.

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: Hsi-yü Tu-hu Fu) 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 AD. 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 was the first direct rule by a Chinese government of the area. It consisted of various vassal states and Han garrisons placed under the authority of a protector-general of the Western Regions, who was appointed by the Han court.

Khoja or Khwaja (Kazakh: қожа; Kyrgyz: кожо; Uyghur: خوجا; Persian: خواجه; Tajik: хӯҷа; Uzbek: xo'ja; Chinese: 和卓; pinyin: hézhuó), a Persian word literally meaning 'master' or ‘lord’, was used in Central Asia as a title for the descendants of the noted Central Asian Naqshbandi Sufi teacher, Ahmad Kasani (1461–1542) or others in the Naqshbandi intellectual lineage prior to Baha al-Din Naqshband. The most powerful religious figure in the late Timurid era was the Naqshbandi Shaykh Khwaja Ahrar. The Khojas often were appointed as administrators by Mongol rulers in the Altishahr or present-day region of Tarim Basin in Xinjiang, China.

The Khojas of Altishahr claimed to be Sayyids (descendants of Muhammad) and they are still regarded as such by the fraternity people of Altishahr. Although Ahmad Kasani himself, known as Makhdūm-i-Azam or "Great Master" to his followers, never visited Altishahr (today's Tarim Basin), many of his descendants, known as Makhdūmzādas and bearing the title Khoja (properly written and pronounced Khwaja) played important parts in the region's politics from the 17th to 19th centuries.

Amursana (Mongolian ᠠᠮᠤᠷᠰᠠᠨᠠᠭ᠎ᠠ; Chinese: 阿睦爾撒納; 1723 – 21 September 1757) was an 18th-century taishi (太师; 太師) or prince of the Khoit-Oirat tribe that ruled over parts of Dzungaria and Altishahr in present-day northwest China. Known as the last great Oirat hero, Amursana was the last of the Dzungar rulers. The defeat of his rebel forces by Qing dynasty Chinese armies in the late 1750s signaled the final extinction of Mongol influence and power in Inner Asia, ensured the incorporation of Mongol territory into the Qing Chinese Empire, and brought about the Dzungar genocide, the Qing Emperor's "final solution" to China's northwest frontier problems.
