Chu (, Hanyu Pinyin: Chǔ, Old Chinese: &ast;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 () and Jingchu (), 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. For more than 400 years, the Chu capital Danyang was located at the junction of the Dan and Xi Rivers near present-day Xichuan County, Henan, but later moved to Ying. The house of Chu originally bore the clan name Nai ( OC: /*rneːlʔ/) which was later written as Mi ( OC: /*meʔ/). They also bore the lineage name Yan ( OC: /*qlamʔ/, /*qʰɯːm/) which would later be written Xiong ( OC: /*ɢʷlɯm/). History Founding In Chinese mythology, according to legends recounted in Sima Qian's Records of the Grand Historian, the ruling family of Chu descended from the Yellow Emperor and his grandson and successor Zhuanxu. Zhuanxu's great-grandson Wuhui () was put in charge of fire by Emperor Ku and given the title Zhurong. Wuhui's son Luzhong () had six sons, all born by Caesarian section. The youngest, Jilian, adopted the ancestral surname Mi. 's descendant Yuxiong was the teacher of King Wen of Zhou (r. 1099–1050 BCE). After the Zhou overthrew the Shang dynasty, King Cheng (r. 1042–1021 BCE) enfeoffed Yuxiong's great-grandson Xiong Yi with the fiefdom of Chu in the Nanyang Basin and the hereditary title of (zǐ, "viscount"). Then the first capital of Chu was established at Danyang (present-day Xichuan in Henan). Western Zhou In 977 BCE, during his campaign against Chu, King Zhao of Zhou's boat sank and he drowned in the Han River. After this death, Zhou ceased to expand to the south, allowing the southern tribes and Chu to cement their own autonomy much earlier than the states to the north. The Chu viscount Xiong Qu overthrew E in 863 BCE but subsequently made its capital Ezhou one of his capitals. In either 703 or 706, the ruler Xiong Tong became the ruler of Chu.
