context_page_description: Wu, commonly known as Dong Wu or Sun Wu, was one of the three major states that competed for supremacy over China in the Three Kingdoms period. It previously existed from 220–222 as a vassal kingdom nominally under Cao 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. Its name was derived from the place it was based in — the Jiangnan region, which was also historically known as "Wu". It was referred to as "Dong Wu" or "Sun Wu" by historians to distinguish it from other Chinese historical states with similar names which were also located in that region, such as the Wu state in the Spring and Autumn period and the Wuyue kingdom in the Five Dynasties and Ten Kingdoms period. It was called "Eastern Wu" because it occupied most of eastern China in the Three Kingdoms period, and "Sun Wu" because the family name of its rulers was "Sun". During its existence, Wu's capital was at Jianye, but at times it was also at Wuchang.
context_section_description: The culture of Wu was most solidified under the reign of Sun Quan from 229 to 252. Migrations from the north and the needed settlement from the Shanyue barbarians made it possible for the increase in manpower, agriculture, and settling the lower most parts of Wu. Along with that, river transportation became a huge factor and flourished as the Jiangnan and Zhedong canals were finished with construction. After the Battle of Xiaoting and during the invasions of Wu by Wei in the 220s, Shu was able to reestablish their trade and relationships with Wu. Shu's cotton was a great influx for Wu, and the development of shipbuilding, salt, and metal industries was greatly increased.
  The fact of inflation and economic problems still were in existence since the Han dynasty. Sun Quan tried to start a currency of large coins manufactured by copper. He also tried to prohibit private minting. This policy was terminated in 246 due to ineffectiveness.
  Eastern Wu was able to make close overseas trade with countries such as Vietnam and Cambodia. Wu also traded with India and the Middle East.
