Rebellions
Muzong's reign was plagued by plots and rebellions against him from both the Yelu imperial clan and the Xiao consort clan. He fired many ministers who worked for Emperor Shizong, and used force against those who dared to rebel against him. However, his brutal use of force and repression was eventually able to restore stability and the authority of the throne.
In June 952, his uncle wrote a letter to the Later Zhou Dynasty, saying that "Muzong is a drunkard and has no ambition". Muzong discovered the letter and executed his uncle. In July 952, Shizong's brother Yelu Loguo attempted to rebel, but Muzong suppressed it and executed him. In October 953, Muzong's brother and several high-ranking officials plotted against him. Once again, Muzong discovered the plot and executed most of the plotters, but imprisoned his brother instead of killing him. A similar situation occurred in November 959, where his brother was spared, but the other plotters were killed.
