Empress Cao
Li Siyuan died in late 933, and his second son by Lady Xia, Li Conghou the Prince of Song, succeeded him as emperor. (Lady Xia's older son Li Congrong the Prince of Qin, who had previously been considered the likely heir, had tried to seize power in Li Siyuan's illness, but was killed by the imperial guards.) In 934, Li Conghou honored Empress Cao as empress dowager.
