The Northern Liao (), officially the Great Liao (), was a dynastic regime of China, distinct from the Liao dynasty, established by the Khitan people Yelü clan in northern China. The state only existed for a short period of time between 1122 and 1123.
After the death of Emperor Tianxi, he was succeeded nominally by Yelü Ding, the Prince of Qin. However, as Yelü Ding was in exile with the Emperor Tianzuo, the Empress Dowager Xiao Puxian'nü was made regent. During the regency of Empress Dowager Xiao, her request for the Jin dynasty to recognize Yelü Ding as emperor was denied. As the Jin forces advanced towards the Northern Liao capital, the Empress Dowager Xiao and Yelü Dashi sought refuge at Emperor Tianzuo's exiled court. The Empress Dowager Xiao was executed for rebelling against the Emperor Tianzuo, but Yelü Dashi was spared.Biran (2005), pg 23
In 1123, Nanjing surrendered to the Jin forces. When the Jin army attacked the Emperor Tianzuo's refuge in Qingzhong (south of modern-day Hohhot), he decided to escape to the Western Xia. Yelü Yali, the Prince of Liang, fled north and proclaimed himself emperor, only to die five months later. His son, Yelü Zhulie, succeeded him, but was killed one month later by his own troops.Biran (2005). pp 24-25 The death of Yelü Zhulie in 1123 marked the end of Northern Liao. In 1124, Yelü Dashi would lead a faction of the Liao court to Central Asia where he proclaimed the Qara Khitai. The Liao dynasty led by Emperor Tianzuo would collapse in 1125 when he was captured by the Jin general Wanyan Loushi.
