**Dingnan Jiedushi **, also known as Xiasui Jiedushi, was a jiedushi created in 787 by the Tang dynasty that lasted until the early Northern Song dynasty, when its ruler Li Yuanhao proclaimed himself emperor and established the Western Xia dynasty. Its seat was in modern Yulin, Shaanxi. Its rulers were of Tangut ethnicity starting from Li Sigong (Tuoba Sigong), and they effectively ruled the circuit in de facto independence despite its nominal submission to the central Chinese dynasties. Attempts by the Later Tang and Song dynasty to dislodge the family from its rule of Dingnan Jiedushi were unsuccessful, and the region eventually became the independent dynasty of Western Xia.
