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).
King Zhaoxiang of Qin
In 315 BC, the two splinter states of East Zhou and West Zhou declared autonomy and divided up the remaining crown lands between themselves, reducing the King of Zhou, whose seat, Chengzhou, was within East Zhou, to more or less a puppet at the mercy of the duke's charity. When King Nan of Zhou ascended in 314 BC, he was expelled by the Duke of East Zhou, who no longer wanted to provide for a less than useful monarch. King Nan was forced to beg for protection from the Duke of West Zhou, and moved out of Chengzhou to Wangcheng.
