Qara Khitai in the context of "Liao dynasty"

The Jin dynasty (/dʒɪn/, Chinese: 金朝; pinyin: Jīn cháo), officially the Great Jin (大金; Dà Jīn), was a Jurchen-led imperial dynasty of China and empire ruled by the Wanyan clan that existed between 1115 and 1234. It is also often called the Jurchen dynasty or the Jurchen Jin after the ruling Jurchen people. At its peak, the empire extended from Outer Manchuria in the north to the Qinling–Huaihe Line in the south.

The Jin dynasty emerged from Wanyan Aguda's rebellion against the Liao dynasty (916–1125), which held sway over northern China until being driven by the nascent Jin to the Western Regions, where they would become known in Chinese historiography as the Western Liao. After conquering the Liao territory, the Jin launched a century-long campaign against the Song dynasty (960–1279) based in southern China, whose rulers were ethnically Han Chinese. Over the course of the Jin's rule, their emperors adapted to Han customs and even fortified the Great Wall against the ascendant Mongol Empire. The Jin also oversaw a number of internal cultural advances, such as the revival of Confucianism.

The Khwarazmian Empire (English: /kwəˈræzmiən/), or simply Khwarazm, was a culturally Persianate, Sunni Muslim empire of Turkic mamluk origin. Khwarazmian Empire ruled large parts of present-day Central Asia, Afghanistan, and Iran from 1077 to 1231; first as vassals of the Seljuk Empire and the Qara Khitai (Western Liao dynasty), and from circa 1190 as independent rulers up until the Mongol invasion in 1219–1221.

The date of the founding of the state remains debatable. The dynasty that ruled the empire was founded by Anush Tigin (Gharachai), initially a Turkic slave of the rulers of Gharchistan, later a Mamluk in the service of the Seljuks. However, it was under Ala ad-Din Atsiz (r. 1127–1156), a descendant of Anush Tigin, that Khwarazm became independent from its neighbors.

Between 1219 and 1221, the Mongol forces under Genghis Khan invaded the lands of the Khwarazmian Empire in Central Asia. The campaign, which followed the annexation of the Qara Khitai Khanate, saw widespread devastation and atrocities. The invasion marked the completion of the Mongol conquest of Central Asia, and began the Mongol conquest of Persia.

Both belligerents, although large, had been formed recently: the Khwarazmian dynasty had expanded from their homeland to replace the Seljuk Empire in the late 1100s and early 1200s; nearly simultaneously, Genghis Khan had unified the Mongolic peoples and conquered the Western Xia dynasty. Although relations were initially cordial, Genghis was angered by a series of diplomatic provocations. When a senior Mongol diplomat was executed by Khwarazmshah Muhammed II, the Khan mobilized his forces, estimated to be between 90,000 and 200,000 men, and invaded. The Shah's forces were widely dispersed and probably outnumbered—realizing his disadvantage, he decided to garrison his cities individually to bog the Mongols down. However, through excellent organization and planning, the Mongols were able to isolate and conquer the Transoxianan cities of Bukhara, Samarkand, and Gurganj. Genghis and his youngest son Tolui then laid waste to Khorasan, destroying Herat, Nishapur, and Merv, three of the largest cities in the world. Meanwhile, Muhammed II was forced into flight by the forces of Mongol generals Subutai and Jebe; unable to reach any bastions of support, he died destitute on an island in the Caspian Sea. His son and heir Jalal-al Din managed to mobilize substantial forces, defeating a Mongol general at the Battle of Parwan, but these were crushed by Genghis at the Battle of the Indus a few months later.

The Western Xia or the Xi Xia (Chinese: 西夏; pinyin: Xī Xià; Wade–Giles: Hsi Hsia), officially the Great Xia (大夏; Dà Xià; Ta Hsia), also known as the Tangut Empire, and known as Mi-nyak to the Tanguts and Tibetans, was a Tangut-led imperial dynasty of China that existed from 1038 to 1227. At its peak, the dynasty ruled over modern-day north-central China, including parts of Ningxia, Gansu, eastern Qinghai, Northern Shaanxi, North Eastern Xinjiang, and Southwest Inner Mongolia, and Southernmost Outer Mongolia, measuring about 800,000 square kilometres (310,000 square miles).

The capital of Western Xia was Xingqing (modern Yinchuan); another major Xia city and archaeological site is Khara-Khoto. Western Xia was annihilated by the Mongols in 1227. Most of its written records and architecture were destroyed, so the founders and history of the empire remained obscure until 20th-century research in China and the West. Today the Tangut language and its unique script are extinct, only fragments of Tangut literature remain.

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.

Hotan Prefecture (see also § Etymology) is located in the Tarim Basin region of southwestern Xinjiang, China, bordering the Tibet Autonomous Region to the south and Union Territory of Ladakh and Gilgit-Baltistan to the west. The vast majority of the Aksai Chin region which is disputed between China and India is administered as part of Hotan Prefecture. The seat of Hotan Prefecture is Hotan and its largest county by population is Karakax County. The vast majority of the residents of the prefecture are Muslim Uyghurs and live around oases situated between the desolate Taklamakan Desert and Kunlun Mountains.

The region was the center of the ancient Iranian Saka Buddhist Kingdom of Khotan. Later, the region was part of the Kara-Khanid Khanate, followed by the Qara Khitai, Chagatai Khanate, Moghulistan and the Dzungar Khanate, which was conquered by the Qing dynasty of China. Hotan became part of Xinjiang under Qing rule. In the 1930s, the Khotan Emirate declared independence from China. The People's Liberation Army entered Hotan in 1949.

The Kara-Khanid Khanate (Persian: قراخانیان, romanized: Qarākhāniyān; Chinese: 喀喇汗國; pinyin: Kālā Hánguó), also known as the Karakhanids, Qarakhanids, Ilek Khanids or the Afrasiabids (Persian: آل افراسیاب, romanized: Āl-i Afrāsiyāb, lit. 'House of Afrasiab'), was a Karluk Turkic khanate that ruled Central Asia from the 9th to the early 13th century. The dynastic names of Karakhanids and Ilek Khanids refer to royal titles with Kara Khagan being the most important Turkic title up until the end of the dynasty.

The Khanate conquered Transoxiana in Central Asia and ruled it independently between 999 and 1089. Their arrival in Transoxiana signaled a definitive shift from Iranic to Turkic predominance in Central Asia, yet the Kara-khanids gradually assimilated the Perso-Arab Muslim culture, while retaining some of their native Turkic culture. The Khanate split into the Eastern and Western Khanates in the 1040s. In the late 11th century, they came under the suzerainty of the Seljuk Empire followed by the Qara Khitai (Western Liao dynasty) who defeated the Seljuks in the Battle of Qatwan in 1141. The Eastern Khanate ended in 1211, and the Western Khanate was extinguished by the Khwarazmian Empire in 1212.

The Anushtegin dynasty or Anushteginids (English: /ænuʃtəˈɡinid/, Persian: خاندان انوشتکین), also known as the Khwarazmian dynasty (Persian: خوارزمشاهیان) was a Sunni Muslim dynasty of Turkic mamluk origin from the Bekdili clan of the Oghuz Turks. The Anushteginid dynasty ruled the Khwarazmian Empire, consisting in large parts of present-day Central Asia, Afghanistan and Iran in the approximate period of 1077 to 1231, first as vassals of the Seljuks and the Qara Khitai (Western Liao), and later as independent rulers, up until the Mongol conquest of the Khwarazmian Empire in the 13th century.

The dynasty was founded by commander Anushtegin Gharchai, a former Turkic slave of the Seljuq sultans, who was appointed as governor of Khwarazm. His son, Qutb ad-Din Muhammad I, became the first hereditary Shah of Khwarazm. Anush Tigin may have belonged to either the Begdili tribe of the Oghuz Turks or to Chigil, Khalaj, Qipchaq, Qangly, or Uyghurs.
