King Zhaoxiang of Qin
Because King Zhaoxiang had not yet legally come of age (traditionally at the age of 20), his mother, who was now known as Queen Dowager Xuan, became the regent. She was supported by her brothers, Wei Ran and Mi Rong (羋戎), as well as two other sons, Prince Yi (公子悝) and Prince Fu (公子巿), the four of them collectively known as the "Four Nobles" (四貴).
Empress Dowager Wang Baoming
Empress Dowager Wang Baoming (王寶明) (455–512), formally Empress An (安皇后, literally "the peaceful empress"), semi-formally Empress Dowager Xuande (宣德太后), was an empress dowager of the Chinese dynasty Southern Qi. She was never empress, but as she was the wife of Xiao Zhangmao, the oldest son and crown prince of Emperor Wu, who was posthumously honored as an emperor, and the mother of his son Xiao Zhaoye, who later became emperor, she was considered an empress.
