Changsha has a history of more than 3,000 years. Changsha was the capital of Changsha State in the Han Dynasty (206 BC – 220 AD), and the capital of the Chu State (907–951) in the Ten Kingdoms period. The lacquerware and Silk Texts recovered from Mawangdui (2nd century BC) there are an indication of the richness of local craft traditions. In 1904, Changsha was opened to foreign trade, and large numbers of Europeans and Americans settled there.
Changsha was the site of Mao Zedong's conversion to communism. It was also the scene of major battles in the Sino-Japanese War (1931–1945) and was briefly occupied by the Japanese. Changsha is now an important commercial, manufacturing and transportation centre.
