Xinjiang Uyghur Autonomous Region in the context of "Sibe people"

Turkestan, also spelled Turkistan, is a historical name for the part of Asia lying between the Caspian Sea to the west, Siberia to the north, the Gobi Desert to the east, and Iran, Afghanistan, Pakistan, and Tibet to the south. Turkestan is primarily inhabited by Turkic peoples, as well as Russian and Tajik-Persian minorities. It is subdivided into West Turkestan, which historically belonged to Russia, and East Turkistan or Xinjiang, which forms part of China.

Throughout history, the region has been exposed to the invasion of several different groups and kingdoms, including the Huns, Hepthalites, Bactrians, Imperial China, Arab Caliphate, Hellenistic Macedonian Empire, Achaemenid Empire, as well as various Turkic states and the Mongol Empire. The Qara Khitai also briefly controlled a significant bulk of Turkestan.

Uyghur, formerly known as Turki or Eastern Turki, is a Turkic language of the Karluk branch, with 8 to 13 million native speakers (as of 2021). It is spoken primarily by the Uyghur people, most of whom live in what is now the Xinjiang Uyghur Autonomous Region of Western China. Apart from Xinjiang, significant communities of Uyghur speakers are also located in Kazakhstan, Kyrgyzstan, and Uzbekistan, and various other countries. Uyghur is a lingua franca of Xinjiang; it is widely used in both social and official spheres, as well as in print, television, and radio. Other ethnic minorities in Xinjiang also use Uyghur as a common language.

Uyghur belongs to the Karluk branch of the Turkic language family, which includes languages such as Uzbek. Like many other Turkic languages, Uyghur displays vowel harmony and agglutination, lacks noun classes or grammatical gender, and is a left-branching language with subject–object–verb word order. More distinctly, Uyghur processes include vowel reduction and umlauting, especially in northern dialects. In addition to other Turkic languages, Uyghur has historically been strongly influenced by Arabic and Persian, and more recently by Russian and Mandarin Chinese.

The Yarkand River (also spelled Yarkent River) is a river in the Xinjiang Uyghur Autonomous Region of western China. It originates in the Siachen Muztagh in a part of the Karakoram range and flows into the Tarim River, with which it is sometimes identified. However, in modern times, the Yarkand river drains into the Midstream Reservoir and exhausts its supply without reaching the Tarim river. The Yarkand River is approximately 1,332.25 km (827.82 mi) in length, with an average discharge of 210 m/s (7,400 cu ft/s).

A part of the river valley is known to the Kyrgyz people as Raskam Valley, and the upper course of the river itself is called the Raskam River. Another name of the river is Zarafshan. The area was once claimed by the ruler of Hunza.

The Uyghur Arabic alphabet (Uyghur: ئۇيغۇر ئەرەب يېزىقى, romanized: Uyghur Ereb Yëziqi, abbr. UEY) is a version of the Arabic alphabet used for writing the Uyghur language, primarily by Uyghurs living in Xinjiang Uyghur Autonomous Region. It is one of several Uyghur alphabets and has been the official alphabet of the Uyghur language since 1982.

The first Perso-Arabic derived alphabet for Uyghur was developed in the 10th century, when Islam was introduced there. The alphabet was used for writing the Chagatai language, the regional literary language, and is now known as the Chagatay alphabet (Uyghur: كونا يېزىق, romanized: Kona Yëziq, lit. 'old script'). It was used nearly exclusively up to the early 1920s. This alphabet did not represent Uyghur vowels and according to Robert Barkley Shaw, spelling was irregular and long vowel letters were frequently written for short vowels since most Turki speakers were unsure of the difference between long and short vowels. The pre-modification alphabet used Arabic diacritics (zabar, zer and pesh) to mark short vowels. Also, the ة‎ was used to represent a short [a] by some Turki writers.
