Junggar Basin in the context of "Xinjiang Autonomous Region"

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.

The Dzungar Khanate (Mongolian: ᠵᠡᠭᠦᠨᠭᠠᠷ ᠣᠯᠣᠰ Зүүнгар Улс), also known as the Zunghar Khanate or Junggar Khanate, was a nomadic khanate of Oirat Mongol origin. At its greatest extent, it covered an area from southern Siberia in the north to present-day Kyrgyzstan in the south, and from present-day west of Mongolia and the Great Wall of China in the east to present-day Kazakhstan in the west. The core of the Dzungar Khanate is today part of northern Xinjiang, also called Dzungaria.

About 1620 the western Mongols, known as the Oirats, united in the Junggar Basin in Dzungaria. In 1678, Galdan received from the Dalai Lama the title of Boshogtu Khan, making the Dzungars the leading tribe within the Oirats. The Dzungar rulers used the title of Khong Tayiji, which translates into English as "crown prince". Between 1680 and 1688, the Dzungars conquered the Tarim Basin, which is now southern Xinjiang, and defeated the Khalkha Mongols to the east. In 1696, Galdan was defeated by the Qing dynasty and lost Outer Mongolia. In 1717, the Dzungars conquered Tibet, but were driven out in 1720 by the Qing. From 1755 to 1758, Qing China took advantage of a Dzungar civil war to conquer Dzungaria and killed 70–80% of the Dzungar population. The destruction of the Dzungars led to the Qing conquest of Mongolia, Tibet, and the creation of Xinjiang as a political administrative unit.

The Altai Mountains (/ɑːlˈtaɪ/ ahl-TY) are a mountain range in Central Asia, where Russia, China, Mongolia, and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The highest summit of the range is Belukha, whose summit reaches 4,506 m (14,783 ft) above sea level. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. In the southwest, it is separated from the higher Tian Shan range by the Junggar Basin. It spans from about 45° to 52° N and from about 84° to 99° E.
