The two-year-old son of Emperor Jingzong of Western Xia had succeeded his father in 1048 as Emperor Yizong.
His mother had become the regent and a year later, the Liao Dynasty had launched an invasion of Western Xia, causing Western Xia to submit to the Liao Dynasty as a vassal state.
In 1056, the Dowager is killed and Yizong's uncle becomes the regent.
Yizong, discovering a plot against him by his uncle and cousin in 1061, has them executed and assumes direct control of Western Xia.
