Du, empress dowager of the Song Dynasty
Empress Dowager Du (杜太后, given name unknown, c. 902 – 17 July 961) was an empress dowager of imperial China's Song Dynasty. She was the wife of general Zhao Hongyin and the mother of Emperor Taizu of Song, who founded the Song Dynasty.

After her death, another son, Emperor Taizong, succeeded Emperor Taizu, claiming legitimacy on grounds of their mother's will, alleged to be sealed in a golden shelf at her death. Many historians believe that this was actually a fabrication by Emperor Taizong.
