Eastern Wu

Eastern Wu, also known as Sun Wu, was a dynastic state and one of the three major states that competed for supremacy during China's Three Kingdoms period. It was founded in 229 CE when its ruler, Sun Quan, declared himself emperor. Previously, it existed as a vassal kingdom from 220 to 222 AD, declaring independence in November 222 AD. The state was based in the Jiangnan region, historically known as Wu, and occupied much of eastern China. Its capital was sometimes at Jianye (present-day Nanjing) and sometimes at Wuchang (present-day Ezhou). Eastern Wu was dissolved in 280 CE.
