Xu (state)The State of Xu () (also called Xu Rong (徐戎) or Xu Yi (徐夷) by its enemies) was an independent Huaiyi state of the Chinese Bronze Age that was ruled by the Ying family (嬴) and controlled much of the Huai River valley for at least two centuries. It was centered in northern Jiangsu and Anhui. An ancient but originally minor state that already existed during the late Shang dynasty, Xu was subjugated by the Western Zhou dynasty around 1039 BC, and was gradually sinified from then on.
DongyiThe Dongyi or Eastern Yi () was a collective term for ancient peoples found in Chinese records. The definition of Dongyi varied across the ages, but in most cases referred to inhabitants of eastern China. Then later, the Korean peninsula and Japanese Archipelago. Dongyi refers to different group of people in different periods. As such, the name "Yí" was something of a catch-all and was applied to different groups over time. According to the earliest Chinese record, the Zuo Zhuan, the Shang Dynasty was attacked by King Wu of Zhou while attacking the Dongyi and collapsed afterward.
Chu (state)Chu (, Hanyu Pinyin: Chǔ, Old Chinese: *s-r̥aʔ), or Ch'u in Wade–Giles romanization, was a Zhou dynasty vassal state. Their first ruler was King Wu of Chu in the early 8th century BCE. Chu was located in the south of the Zhou heartland and lasted during the Spring and Autumn period. At the end of the Warring States period it was destroyed by the Qin in 223 BCE during the Qin's wars of unification. Also known as Jing (荊) and Jingchu (荊楚), Chu included most of the present-day provinces of Hubei and Hunan, along with parts of Chongqing, Guizhou, Henan, Anhui, Jiangxi, Jiangsu, Zhejiang, and Shanghai.
Spring and Autumn periodThe Spring and Autumn period was a period in Chinese history from approximately 770 to 481 BCE (or later) which corresponds roughly to the first half of the Eastern Zhou period. The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 481 BCE, which tradition associates with Confucius (551–479 BCE). During this period, royal control over the various local polities eroded as regional lords increasingly exercised political autonomy, negotiating their own alliances, waging wars amongst themselves, up to defying the king's court in Luoyi.
