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.
Duke Qing of Qi
Duke Qing of Qi (; died 582 BC) was from 598 to 582 BC ruler of the State of Qi, a major power during the Spring and Autumn period of ancient China. His personal name was Lü Wuye (呂無野), ancestral name Jiang (姜), and Duke Qing was his posthumous title.
