Three Kingdoms "WU" Calligraphy Art Poster

"WU" (吳) or Eastern Wu (東吳) was one of the three major states that competed for supremacy over China in the Three Kingdoms period, based in the Jiangnan (Yangtze River Delta) region, which was also historically known as "Wu". It previously existed from 220 - 222 as a vassal kingdom nominally under Wei, its rival state, but declared independence from Wei and became a sovereign state in 222. It became an empire in 229 after its founding ruler, Sun Quan, declared himself emperor. The Three Kingdoms (220 - 280 AD) was the tripartite division of China between the states of Wei, Shu, and Wu. It started with the end of the Han dynasty and was followed by the Jin dynasty. The Three Kingdoms period is one of the bloodiest in Chinese history, 60 years of war has cause the population of China greatly declined from over 50 millions to around 2 millions when the Jin Dynasty was founded, which was only a fraction of the population before the great devision of China.
