The land area of Chu is the largest among the vassal States, accounting for almost half of the world. In the Zhou Dynasty's war to destroy the Shang Dynasty, the tribal leaders of Chu took refuge in Zhou Wenwang, so they were awarded the title of "Zi", which was the lowest rank in the Spring and Autumn Period. Later, Xiong Yi, the first monarch of Chu, led the people of Chu to fight hard and expand their territory to become a big country in the south of the Yangtze River. After the decline of the Zhou royal family, Xiong Tong became king on his own. King Wen of Chu moved his capital to Pidu and gradually competed for the Central Plains. In the 6th century BC, there was a king Chu Zhuangwang in the State of Chu (one of the five tyrants in the Spring and Autumn Period). Chu Zhuangwang appointed Sun Shuai as Lingyin, attaching importance to social and economic development.
Under the leadership of Liu, Chu defeated the northern state of Jin in the Battle of Tai. Later, Xiao was destroyed one after another and Song was struck three times, becoming the overlord in the mid-Spring and Autumn Period. Chu Zhuangwang deliberately asked the size and weight of Jiuding, the king of Zhou, and produced an idiom "Winning the Central Plains". But later, Chu was defeated by Wu, and the whole country perished. With the help of Qin, the country successfully restored the motherland. During the Warring States Period, the State of Chu made use of Wuqi to carry out political reform, which was powerful and was called one of the Seven Heroes of the Warring States Period. After Ying Zheng succeeded to the throne, he began a war to unify the six countries. Wang Jian led 600,000 troops to fight against Xiang Yan, and finally Chu was destroyed.
Chu existed for 1000 years, which was founded by Xiong Yi and later destroyed by Qin. At the end of Qin Dynasty, Xiang Yu, a noble of Chu State, destroyed Qin again.
