Hunan's primeval forests were first occupied by the ancestors of the modern Miao, Tujia, Dong and Yao peoples. The province entered written Chinese history around 350 BC, when under the kings of the Zhou dynasty, the province became part of the State of Chu. After Qin conquered the Chu heartland in 278 BC, the region came under the control of Qin, and then the Changsha Kingdom during the Han dynasty.
