Dzungaria in the context of "Irtysh"

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 Mongol heartland or Mongolian heartland is the contiguous geographical area in which the Mongol people have primarily lived, particularly as a historiographic term. It is generally considered to comprise the Mongolian Plateau and some adjacent territories, although its exact extent has been changing over the course of history—particularly since the rise of the Mongol Empire in the 13th century. The area is also described as the heartland of the Mongol Empire during its greatest extent, when it stretched from the Sea of Japan in the east to the Middle East and Eastern Europe in the west, making it the largest contiguous land empire in human history.

The modern area that the Mongols live in approximately includes: the modern state of Mongolia; the Inner Mongolia Autonomous Region, along with Dzungaria in Xinjiang and parts of Manchuria, Qinghai, and Ningxia in China; as well as the Buryatia Republic and a few smaller territories in Russia. The Mongolic peoples in this area share the common traditional Mongol culture as well as the Mongol language to varying levels. With the exception of the Mongolian state, all areas in the Mongol heartland have non-Mongol majorities.

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.

China proper, also called Inner China or Han China, are terms used primarily in the Western world in reference to the traditional "core" regions of Chinese civilization centered around the Yellow River and Yangtze River valleys. There is no fixed definition for China proper as many administrative, cultural and territorial shifts have occurred throughout history. One definition refers to the original heartland regions of the Chinese civilization, the Central Plain (southern North China Plain around the lower Yellow River valley) as well as the historical Nine Provinces; another to the Eighteen Provinces inside Shanhai Pass designated by the Qing regime. In contrast, Outer China is a term usually includes the peripheral marchland regions such as Gobi Desert,, Tarim Basin, Northeast China, Dzungaria, Tibetan Plateau and Yungui Plateau, which were historically autonomous regions with unstable allegiance to the authority of Chinese monarchs.

The term was first used by the Europeans during the 17th century to distinguish the historical "Han lands" (Chinese: 漢地, i.e. regions long dominated by the majority Han Chinese population) from "frontier" regions of China where Han populations intermix with other indigenous ethnicities (e.g. Turkic peoples such as Uyghurs, Kazakhs and Uzbeks, Mongolic peoples, and Tibeto-Burmese peoples such as Tibetans, Yi and Bai) and newer foreign immigrants (e.g. Slavic colonists such as Russians and Ukrainian Cossacks), sometimes known as "Outer China". There was no direct translation for "China proper" in the Chinese language at the time due to differences in terminology used by the Qing regime to refer to the regions.

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 Dzungar genocide (Chinese: 準噶爾滅族; pinyin: Zhǔngáěr mièzú) was the mass extermination of the Dzungar people (Oirat Mongols) by the Qing dynasty. The Qianlong Emperor ordered the genocide after the rebellion in 1755 by Dzungar leader Amursana against Qing rule, after the dynasty first conquered the Dzungar Khanate with Amursana's support. The genocide was perpetrated by Manchu and Han generals of the Qing army, supported by Turkic oasis dwellers (now known as Uyghurs) who rebelled against Dzungar rule.

The Dzungar Khanate was a confederation of several Tibetan Buddhist Oirat Mongol tribes that emerged in the early 17th century, and the last great nomadic empire in Asia. Some scholars estimate that about 80% of the Dzungar population, or around 500,000 to 800,000 people, were killed by a combination of warfare and disease during or after the Qing conquest in 1755–1757. After wiping out the native population of Dzungaria, the Qing government then resettled Han, Hui, Uyghur, and Sibe people on state farms in Dzungaria, along with Manchu Bannermen to repopulate the area.

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.
