Eastern Wu

Eastern Wu was one of the three major states of China's Three Kingdoms period, built on territory in the Yangtze River Delta and southern China that Sun Ce and his younger brother Sun Quan conquered in the Jiangnan region. After Sun Ce's assassination in 200, Sun Quan took control and ruled autonomously while still nominally acknowledging the Han dynasty, before declaring full independence in November 222 and proclaiming himself emperor in May 229. At its height the state held most of eastern China, including present-day Jiangsu and Zhejiang and parts of Vietnam, governed from capitals that alternated between Jianye, now Nanjing, and Wuchang, now Ezhou. Eastern Wu, and the Three Kingdoms period itself, came to an end on 31 May 280, when its last ruler, Sun Hao, surrendered to the Jin dynasty after a coordinated Jin military campaign.
