The Eastern Zhou (//; Chinese: 東周; pinyin: Dōngzhōu; 770–256 BC) was the second half of the Zhou dynasty of ancient China. It is divided into two periods: the Spring and Autumn and the Warring States.
This brought about the beginning of the Eastern Zhou dynasty (as opposed to Western Zhou dynasty), so named due to Luoyi being situated to the east of Haojing. Over 25 kings reigned over the Eastern Zhou Dynasty, lasting 515 years in all.
With the death of King You of Zhou, the last king of the Western Zhou Dynasty, ascended Crown Prince Yijiu was proclaimed the new king by the nobles from the states of Zheng, Lü, Qin and the Marquess of Shen. He was King Ping of Zhou. In the second year of his reign, he moved the capital east to Luoyi as Quanrong invaded Haojing, indicating the end of the Western Zhou dynasty. 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. The second half of the Eastern Zhou dynasty, from 475 to 221 BCE, was called the Warring States period, during which the King of Zhou gradually lost his power and ruled merely as a figurehead.
After moving the capital east, the Zhou royal family fell into a state of decline. Also, King Ping’s popularity fell as rumors went that he had killed his father. With vassals becoming increasingly powerful, strengthening their position through defeating other rival states, and increasing invasion from neighboring countries, the king of Zhou was not able to master the country. Constantly, he would have to turn to the powerful vassals for help. The most important vassals (known later as the twelve vassals) came together in regular conferences where they decided important matters, such as military expeditions against foreign groups or against offending nobles. During these conferences one vassal ruler was sometimes declared hegemon. Chancellor Guan Zhong of Qi initiated a policy "Revere the king, expel the barbarians" (Chinese: 尊王攘夷, see Sonnō jōi). Adopting and adhering to it, Duke Huan of Qi assembled the vassals to strike down the threat of barbarians from the country. During the Warring States period, many of the leaders of the vassals’ clamoring for kingship further limited the Zhou royal family’s influence.
In 635 BCE, the Chaos of Prince Dai took place. 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. In 632 BCE, King Xiang of Zhou was forced by Duke Wen of Jin to attend the conference of vassals in Jiantu.
In 606 BCE, King Zhuang of Chu inquired for the first time regarding the "weight of the cauldrons" (问鼎之轻重) only to be rebuffed by the Zhou minister Wangsun Man (王孙满). Asking such a question was at that time a direct challenge to the power of the reigning dynasty.
At the time of King Nan of Zhou, the kings of Zhou had lost almost all political and military power, as even their remaining crown land was split into two states or factions, led by rival feudal lords: West Zhou, where the capital Wangcheng was located, and East Zhou, centered at Chengzhou and Kung. 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. Seven years later, West Zhou was conquered by Qin.
This period marked a big turn in Chinese history, as the dominant toolmaking material became iron by the end of the period. The Eastern Zhou period was believed to be the beginning of the Iron Age in China.
There was a considerable development in agriculture with a consecutive increase in population. There were constantly fights between vassals to scramble for lands or other resources. People started using copper coins. Education was made universal for civilians. The boundaries between the nobility and the civilians subsided. A revolutionary transformation of the society was taking place, to which the patriarchal clan system made by the Zhou Dynasty could no longer adapt.

Spring and Autumn period
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, defying the king's court in Luoyi, and waging wars amongst themselves. The gradual partition of Jin, one of the most powerful states, marked the end of the Spring and Autumn period, and the beginning of the Warring States period.
Warring States period
The Warring States period was an era in ancient Chinese history following the Spring and Autumn period and concluding with the Qin wars of conquest that saw the annexation of all other contender states, which ultimately led to the Qin state's victory in 221 BCE as the first unified Chinese empire known as the Qin dynasty.
