Xue Ju, emperor of Qin

Xue Ju (薛舉), formally Emperor Wu, was the founding emperor of a short-lived state of Qin at the end of the Chinese Sui dynasty, whose state was eventually destroyed by the Tang dynasty. He rose against Sui rule in 617 and soon controlled modern eastern Gansu, but while he had some successes against Tang forces, was not able to push toward the Tang capital Chang'an before dying of illness in 618. His son Xue Rengao inherited his throne but was soon defeated and killed by the Tang general Li Shimin, ending the state that Xue Ju established.
