The Tangut civilization, also known as the Western Xia dynasty, flourished in northwestern China from the 11th to the 13th centuries. It was established by the Tangut people, who were of Tibetan-Burmese origin. The civilization is notable for its unique language, the Tangut language, and its contributions to art, literature, and Buddhism, particularly the promotion of Vajrayana Buddhism. The Tangut state was strategically located along the Silk Road, facilitating trade and cultural exchange with neighboring regions. The dynasty developed a sophisticated administrative system and built impressive architectural structures, including the capital city of Xiangzhou. The Tangut civilization ultimately fell to the Mongol Empire in the 13th century.
