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 Xiang of Qin
In 771 BC King You of Zhou deposed Crown Prince Yijiu and made Bofu, the son of his favorite concubine Bao Si, the new crown prince. Yijiu was the son of Queen Shen who was the daughter of Marquis of Shen. Marquis of Shen rebelled at the news and made an alliance with the Quanrong tribe to attack the Zhou capital Haojing, killing King You at Mount Li. Marquis of Shen and other feudal rulers then installed Prince Yijiu on the Zhou throne as King Ping of Zhou. As Haojing was now ruined and still under the threat of the Quanrong, it was decided that the Zhou capital would be moved east to Luoyi, and Duke Xiang sent the Qin army to escort King Ping to Luoyi and established him at the new capital. This event marked the start of the Eastern Zhou Dynasty.
