Xiao Tong
In 555, after Western Wei forces had defeated and killed Xiao Yi, Western Wei created Xiao Cha the emperor of (Western) Liang (as Emperor Xuan). While Emperor Xuan posthumously honored Xiao Tong as an emperor and Xiao Tong's wife Crown Princess Cai as an empress, he honored his mother as an empress dowager. After he died in 562 and was succeeded by his son Xiao Kui (as Emperor Ming), Emperor Ming honored her as grand empress dowager. She died about three months after her son.
