According to traditional historical texts, such as the Records of the Grand Historian, in 770 BCE, the Zhou capital was moved from Haojing (Chang'an County in Xi'an City) to Chengzhou, near present-day Luoyang.
In the second year of his reign, he moved the capital east to Luoyi as Quanrong people invaded Haojing, spelling the end of the Western Zhou dynasty.
After he was killed in 750 BCE, there was no officially recognized King of Zhou for 9 more years, until marquis Wen of Jin brought Ping from Shao'e to the Royal Capital (almost certainly referring to Haojing) and enthroned him.
[4][5] The first half of the Eastern Zhou dynasty, from approximately 771 to 476 BCE, was called the Spring and Autumn period, during which more and more dukes and marquesses obtained regional autonomy, defying the king's court in Luoyi, and waging wars amongst themselves.
Chancellor Guan Zhong of Qi initiated a policy "Revere the king, expel the barbarians" (尊王攘夷, see Sonnō jōi).
King Xiang of Zhou turned to Duke Wen of Jin for help, who killed Prince Dai and was rewarded with rule over Henei and Yangfan.
[3] In 606, King Zhuang of Chu inquired for the first time regarding the "weight of the Nine Tripod Cauldrons" only to be rebuffed by the Zhou minister Wangsun Man (王孫滿).
King Nan of Zhou managed to preserve his weakened dynasty through diplomacy and conspiracies for fifty-nine years until his deposition and death by Qin in 256 BCE.
A revolutionary transformation of the society was taking place, to which the patriarchal clan system made by the Zhou Dynasty could no longer adapt.
[8] The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 479 BCE, which tradition associates with Confucius.
During this period, the Zhou royal authority over the various feudal states started to decline, as more and more dukes and marquesses obtained de facto regional autonomy, defied the king's court in Luoyi, and waged wars amongst themselves.
