In the summer of 1029, Da Yanlin rebelled at the Eastern Capital (
Liaoyang), where he had served as a general. He imprisoned minister Xiao Xiaoxian and his wife, and killed the tax commissioners and chief military commander. Da declared himself the
Tianxing Emperor (天興皇帝) of his own Xingliao dynasty (興遼國/흥료국 and proclaimed the
era name "Tianqing" (天慶). One of Da Yanlin's officers, Yang Xiangshi, betrayed him and opened the Eastern Capital's gates to the Khitans. His short lived dynasty came to an end. The old Parhae nobility were resettled near the Supreme Capital while others fled to Goryeo. ==Citations==
