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 Jing of Qi
Duke Jing of Qi (; died 490 BC) was ruler of the State of Qi from 547 to 490 BC. Qi was a major power during the Spring and Autumn period of ancient China. His personal name was Lü Chujiu (呂杵臼), ancestral name Jiang (姜), and Duke Jing was his posthumous title. After the years of unrest as two powerful ministers, Cui Zhu and Qing Feng, sought to control the state of Qi, Duke Jing appointed Yan Ying as his prime minister, and Qi entered a period of relative peace and prosperity.
