Emperor Ai
In 1 BC, Emperor Ai died. In decisive action, Grand Empress Dowager Wang seized power back from Emperor Ai's favorite Dong Xian and made her nephew Wang Mang regent to the succeeding Emperor Ping. Wang Mang, who wanted to extinguish all dissent (and who previously bore a grudge against Emperor Ai for demoting him and extended that grudge to those who supported Emperor Ai) had Empress Dowager Zhao demoted from her position as empress dowager to the title of Empress Xiaocheng. A few months later, she was further demoted to a commoner and ordered to guard her husband's tomb. That day, she committed suicide.
