The Western Xia was a Tangut-led Chinese dynasty which ruled over what are now the northwestern Chinese subdivisions of Ningxia, Gansu, eastern Qinghai, northern Shaanxi, northeastern Xinjiang, southwest Inner Mongolia, and southernmost Outer Mongolia from 1032 until 1227 when they were destroyed by the Mongols. The country was established by the Tangut people; likewise its earliest coins were escribed with Tangut characters, while later they would be written in Chinese. Opposed to Song dynasty coins that often read top-bottom-right-left, Western Xia coins exclusively read clockwise. Despite the fact that coins had been cast for over a century and a half, very little were actually produced and coins from Western Xia are a rarity today. Although the Western Xia cast their own coins barter remained widely used.

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 Buddhist imperial dynasty of China that existed from 1038 to 1227. At its peak, the dynasty ruled over modern-day northwestern 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).
