Wu (simplified Chinese: 吴; traditional Chinese: 吳; pinyin: Wú) was one of the states during the Western Zhou Dynasty and the Spring and Autumn Period. It was also known as Gouwu (勾吳) or Gongwu (工吳) from the pronunciation of the local language.
Wu was located at the mouth of the Yangtze River east of the State of Chu. Its first capital was at Meili (probably in modern Wuxi) and was later moved to Gusu (within modern Suzhou) and then Helu City (the old town of present-day Suzhou).
The rulers of the State of Wu had the surname Ji (姬), the same as the Zhou royal family. According to the Records of the Grand Historian, this was because the rulers of Wu are descended from Taibo, the elder uncle of King Wen. Realizing that his youngest brother, Jili, was wiser than he and deserved to inherit the throne, Taibo fled to Wu and settled there with his other brother Zhongyong. They established their first capital at Meili (梅里), believed to be today's Meicun in Wuxi.
Afterwards, Wu would be a constant threat to the Chu until its demise. Wu fomented rebelliousness among Chu's vassals in the Yangtze valley. In 506 BC, Wu launched a surprise attack and occupied the capital of Chu. Afterwards, Wu was briefly the most powerful nation and turned to other campaigns, defeating the State of Qi in 484 BC.
Ironically, Wu was later threatened by an upstart state to its own south, Yue; Chu then aided Yue's rise as a counter to Wu. Although Wu won a major victory against Yue in 494 BC, it failed to completely subjugate it, in part because of Yue's timely bribing of an important Wu minister. While Wu was engaged in a military campaign in the north, Yue launched a surprise attack on Wu in 482 BC and conquered the capital. Over the next decade, Wu was unable to recover and Yue absorbed the state in 473 BC.
Wu and Yue were masters of metallurgy, fabricating excellent swords with incised messages, geometric patterns, and inlaid gold or silver. Wu and Yue swords tend to use much more tin than copper compared to those of other states. Wu often sent swords as gifts to northern states, such as Qi and Cai. Examples include the spearhead of King Fuchai and the sword of Prince Guang.
"Wu" continues to be used as a name for the region around Suzhou and Shanghai and their regional speech, Wu Chinese. It was employed by other states and princes holding power in the region, most notably Eastern Wu of the Three Kingdoms, and Wu and Wuyue of the Ten Kingdoms.
Possible connection with ancient Japan
Ambassadorial visits to Japan by the later Chinese dynasties Wei and Jin recorded that the Wō people of Japan claimed to be descendants of Taibo of Wu, traditionally believed to be the founder of Wu.
