Yinchuan in the context of "Helan Mountains"

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.

Between 1205 and 1210, and again in 1225-1227, the Mongol Empire embarked on a series of military campaigns that ultimately led to the destruction of the Tangut-led Western Xia dynasty in northwestern China. Hoping to both to plunder and acquire vassalage, Genghis Khan commanded some initial raids against the Western Xia before launching a full-scale invasion in 1209. This was the first major invasion conducted by Genghis, and his first major incursion into China.

The Mongols began a siege of the Western Xia capital Yinchuan that lasted nearly a year, during which the Mongols tried to divert a river to flood the city, but accidentally flooded their own camp instead. Ultimately, Emperor Xiangzong of Western Xia surrendered to the Mongols in January 1210, marking the beginning of a decade of Western Xia vassalage under the Mongols, where they provided support for the Mongol conquest of the Jin dynasty. However, when Genghis invaded the Islamic Khwarazmian Empire in 1219, the Western Xia attempted to break away from Mongol vassalage and form alliances with the Jin and Song dynasties. Angered by the betrayal of the Western Xia, Genghis Khan began a second campaign against them, sending a punitive expedition into Western Xia in 1225. Genghis intended to annihilate the entire Western Xia culture: he methodically destroyed their cities and countryside, and began besieging Yinchuan in 1227. In December, near the end of the siege, Genghis Khan died of unknown causes, which has been presented by some accounts as being the result of wounds he had suffered against the Western Xia. Following Genghis's death, Yinchuan fell to the Mongols, and most of its population was massacred.

Xingqing Prefecture, also known as Irqai, Äriqaya and Egrigaia in Tangut, Secret History of the Mongols and The Travels of Marco Polo respectively, was the capital of Western Xia (Tangut Empire) between the 11th and 13th centuries and its de facto independent precursor Dingnan Jiedushi, in modern Ningxia, China, centering on modern Yinchuan.

After the fall of the Tangut Empire, it was absorbed into imperial China. The Mongol leader and conqueror Genghis Khan, who founded the Mongol Empire, died there on 25 August 1227.

Wuwei (Chinese: 武威; pinyin: Wǔwēi) is a prefecture-level city in northwest central Gansu province. In the north it borders Inner Mongolia, in the southwest, Qinghai. Its central location between three western capitals, Lanzhou, Xining, and Yinchuan makes it an important business and transportation hub for the area. Because of its position along the Hexi Corridor, historically the only route from central China to western China and the rest of Central Asia, many major railroads and national highways pass through Wuwei.

Hetao (Chinese: 河套; pinyin: Hétào; lit. 'river loop') is a C-shaped region in northwestern China consisting of a collection of flood plains stretching from the banks of the northern half of the Ordos Loop, a large northerly rectangular bend of the Yellow River, that forms the river's entire middle section. The region makes up the northern margin of the Ordos Basin, bounded in the west by the Helan Mountains, the north by the Yin Mountains, the east by the northern portion of Lüliang Mountains, and the south by the Ordos Desert and the Loess Plateau (separated by the course of the Ming Great Wall).

The Hetao region is divided into two main sections — the "West Loop" (Chinese: 西套; pinyin: Xītào) in Ningxia, and the "East Loop" (Chinese: 东套; pinyin: Dōngtào) in Inner Mongolia. The west section includes the alluvial Yinchuan Plain (Chinese: 银川平原, a.k.a. Ningxia Plain) around Shizuishan, Yinchuan, and Wuzhong, and the Weining Plain (Chinese: 卫宁平原) around Zhongwei. The east section is further divided into two parts — the western "Back Loop" (Chinese: 后套; pinyin: Hòutào), which includes the Bayannur Plain (Chinese: 巴彦淖尔平原) around Bayannur and Wuhai; and the eastern "Front Loop" Chinese: 前套; pinyin: Qiántào), which includes the Tumochuan Plain (Chinese: 土默川平原) around Baotou and Hohhot.

Lingwu (simplified Chinese: 灵武市; traditional Chinese: 靈武市; pinyin: Língwǔ Shì, Xiao'erjing: لِئٍ‌وُ شِ) is a county-level city of Ningxia Hui Autonomous Region, Southwest China, it is under the administration of the prefecture-level city of Yinchuan.

Shizuishan, formerly Shizuizi, is a prefecture-level city in the Ningxia Hui Autonomous Region of the People's Republic of China. It is the northernmost prefecture in Ningxia and the second most populous, after the regional capital Yinchuan, bordered by Inner Mongolia to all directions except the south. Shizuishan sits on the western bank of the Yellow River on the western side of the Ordos Loop. It was formerly a center for caravans traveling the northern routes to and from Beijing across the Ordos Desert.
