Wu (region)

Wu (吳), is the region with the core area around Lake Tai in Jiangnan (the south of the Yangtze River). Wu region is part of the ancient province Yangzhou in southeast of China. The term "Wu" is the name for several kingdoms based in the area.

The first Wu state was established in the late Western Zhou dynasty. Once considered to be a vassal state of the Zhou Dynasty, it emerged as a major power among the various states in China at the end of the Spring and Autumn period.

The most influential Wu state was Eastern Wu, which existed during the Three Kingdoms period.

In Han dynasty, Wu Prefecture (Wu Jun) was established, and it was part of Yang Commandery (Yang Zhou). Later Wu Commandery (Wu Zhou) was also established. In Sui and Tang dynasties, the names changed several times between Wu and Su and eventually renamed Su Prefecture (Suzhou) in the first year of Qianyuan (CE 758).

There was two Wu Zhou during Southern and Northern Dynasties. Wu Zhou in Northern Dynasties was renamed Yang Zhou (Yangzhou) in the 9th year of Kaihuang in Sui dynasty (CE 589), and at the same time Yang Zhou was renamed Jiang Zhou (Nanjing).

The state of Wu was founded by Taibo and Zhongyong, the first and second son of King Tai of Zhou. Meili (梅里) was the capital city.

Suzhou was the capital city of state of Wu during Warring states period. Su Zhou was also called Wu Zhou.
