The Western Xia Dynasty, also known as the Xi Xia, was a dynasty that ruled from 1038 to 1227 in what is now northwestern China. Founded by the Tangut people, it was known for its unique culture, language, and Buddhist influences. The dynasty established a strong political and military presence, often engaging in conflicts with neighboring states, including the Song Dynasty. The Western Xia was notable for its advancements in architecture and writing, using a script derived from Tibetan and Chinese characters. The dynasty eventually fell to the Mongol Empire under Genghis Khan, leading to its dissolution and the integration of its territory into the larger Mongol realm.
