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).
Queen Dowager Zhao
Zhao Ji (; –228 BC) was the wife of King Zhuangxiang of Qin and the mother of Qin Shi Huang, the first emperor of China. Upon her marriage, she was the Lady Zhao; after the king's death, she was the Queen Dowager Zhao (.
