Western Xia

The Western Xia or the Xi Xia (Chinese: 西夏; pinyin: Xī Xià; Wade–Giles: Hsi¹ Hsia⁴), officially the Great Xia (大夏; Dà Xià; Ta⁴ Hsia⁴), 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, northeastern 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.

The Western Xia occupied the area around the Hexi Corridor, a stretch of the Silk Road, the most important trade route between northern China and Central Asia. They made significant achievements in literature, art, music, and architecture, which was characterized as "shining and sparkling". Their extensive stance among the other empires of the Liao, Song, and Jin was attributable to their effective military organizations that integrated cavalry, chariots, archery, shields, artillery (cannons carried on the back of camels), and amphibious troops for combat on land and water.

The full title of the Western Xia as named by their own state is L1572 L1890 L2937 L4456 reconstructed as /*phiow¹-bjij²-lhjij-lhjij²/, which word by word denotes 'white', 'high', 'kingdom', 'great', or 𗴂𗹭𘜶𗴲𗂧, 'white', 'high', 'great', 'summer', 'kingdom'. The corresponding Chinese name, 白高大夏國 ("White High Great Xia State"), was also used. Chinese and Japanese scholars commonly interpret the first two words as "upper reaches of the White River", which was possibly referring to the Yellow River. Kepping (1994) proposed the translation "the Kingdom of the Great Xia of the White and Lofty", and suggested that the name refers to a peak in the Helan Mountains named the "White and Lofty Mother". The region was known to the Tanguts as /mjɨ-njaa/, and to the Tibetans as Minyak. Another name the Tanguts used for their state was /khjɨ-dwuu-lhjij/ (萬祕國), which means the "State of Ten Thousand Secrets". "Western Xia" or "Xi Xia" is the state's Chinese name. "Western" refers to its location to the west of the Liao (916–1125) and Jin (1115–1234) dynasties, as well as the Song. "Xia" (pointing to the Xia dynasty) is a historical name for the region that originated from the 5th-century Hu Xia dynasty.

The name Tangut is derived from a form first found in the Orkhon inscriptions dated to 735, which is transcribed in Chinese as Tangwu or Tangute (Tangghut (Tangɣud) in Mongolian). Tangut was used a common name for certain tribes in the Amdo-Kokonor-Gansu region until the 19th century. The Tanguts called themselves Minag, transcribed in Chinese as Mianyao or Miyao.

The Tanguts originally came from the Qinghai-Sichuan-Tibet region, whose home originally was in the highlands of western Sichuan. According to Chinese records, which called them the Dangxiang, the Tanguts were descended from the Western Qiang people, and occupied the steppes around Qinghai Lake and the mountains to its south.

In 608, the Tanguts helped the Sui dynasty defeat the Tuyuhun, however they were betrayed by the Sui forces, who took the chance to loot the Tanguts. In 635, they were requested to serve as guides for Emperor Taizong's campaign against Tuyuhun, but the Tang forces double crossed them in a surprise attack and seized thousands of livestock. In retaliation, the Tanguts attacked the Tang and killed thousands of their soldiers.

By the 650s, the Tanguts had left their homeland to escape pressure from the Tibetans and migrated eastward, to what are now parts of Shanxi and Shaanxi. In 584-5 Tuoba Ningzong led the first group of Tanguts to submit to the Sui. In 628-629 another group under the leadership of Xifeng Bulai surrendered to the Tang. After the Tuyuhun were defeated in 635, the Tanguts under Tuoba Chici also surrendered. The 340,000 Tanguts were divided into 32 jimi prefectures under the control of Tangut chieftains appointed as prefects. Another wave of Tanguts entered Tang territory in 692, adding as many as 200,000 persons to the population in Lingzhou and Xiazhou. In 721–722, Tuoba Sitai, a descendant of Tuoba Chici, aided the Tang in putting down a Sogdian-led revolt in Shuofang. By the time of the An Lushan Rebellion in the 750s, the Tanguts had become the primary local power in the Ordos region in northern Shaanxi. In the 760s, the military commander, Ashina Sijian, harassed six Tangut tribes and took their camels and horses. The Tanguts fled west across the Yellow River and started working for the Tibetans as guides on raiding expeditions. In 764, the Tanguts joined the Tibetans and Uyghurs in supporting the Tang rebel Pugu Huaien. After the Tang reasserted their authority, a descendant of Tuoba Chici, Tuoba Chaoguang, was put in charge of the loyal Tanguts. The Yeli, Bali, and Bozhou clans continued to side with the Tibetans, however the Tanguts also came under Tibetan predation, and frontier settlements continued switching between Tang and Tibetan control for many years. In 806, the Acting Minister of Works, Du You, admitted that they treated the Tanguts badly:
