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.
Transition from Ming to Qing
The Jianzhou Jurchen chief, Nurhaci, is retrospectively identified as the founder of the Qing dynasty. In 1616 he declared himself "Khan". His unifying efforts gave the Jurchen the strength to assert themselves backed by an army consisting of majority Han defectors as well as Ming produced firearms. In 1618 he proclaimed Seven Grievances against the Ming and the Ming General Li Yongfang surrendered the city of Fushun in what is now Liaoning province in China's northeast, after Nurhaci gave him an Aisin Gioro princess in marriage and a noble title. The Princess was one of Nurhaci's granddaughters. In a series of successful military campaigns in Liaodong and Liaoxi (east and west of the Liao River), the Jurchens seized a number of Ming cities including Shenyang, which they made into the capital of their newly founded "Later Jin" dynasty, named after a Jurchen polity that had ruled over north China several centuries earlier.
