Qin dynasty
Note: King Zhaoxiang of Qin (秦昭襄王) had already been ruling Qin for 51 years when Qin annihilated the Zhou dynasty; however the other six warring states were still independent regimes. Some Chinese historiographers thus used the next year (the 52nd year of King Zhaoxiang of Qin) as the official succession from the Zhou dynasty.
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.
