耶律大石
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.
