# Wu Commandery

Wu Commandery was a commandery of imperial China. It covers parts of the contemporary Northern Zhejiang and Southern Jiangsu. The capital of Wu commandery was Wu (today's Suzhou). Major counties of Wu commandery include Wu (county), Yuhang county, and Huating county which later became known as Suzhou, Hangzhou and Shanghai.

## History

During its existence, Wu commandery was ruled by various dynasties and regimes. Chronologically, Han dynasty, Eastern Wu, Jin dynasty, Liu Song dynasty, Southern Qi dynasty, Liang dynasty, Chen dynasty, Sui dynasty and Tang dynasty governed Wu commandery in sequence.
In the year of 129, Wu commandery was established during the reign of emperor Shun of Han. When Kuaiji Commandery was divided, lands west of Qiantang river in Kuaiji commandery formed the new Wu commandery. After the division of Kuaiji, Wu constitutes one of the commanderies of Yang Province.
In 195, local strongman and warlord of Fuchun county Sun Ce acquired the entire Wu commandery without the authorization of Han dynasty. His family ruled the commandery until 280. The last ruler of Sun clan Sun Hao divided a part of Wu commandery and formed the new Wuxing Commandery (吴兴郡).
In 548, Military leader Hou Jing started an open rebellion against Emperor Wu of Liang. Wu Commandery was occupied by Hou's army during his rebellion. Local lords Lu Xiang, Lu An and Lu Yingong of Lu clan were defeated. Xiang died out of fear and anger. The rebels caused great damage to the commandery's economy. It was recorded that, in Wu, human bodies were eaten as rations of the rebels.
In 589, Emperor Wen of Sui abolished the commandery system and substituted it with "Zhou" or "Prefecture"(administrative division). Consequently, Wu commandery was renamed as Suzhou. However, In 607, Emperor Yang of Sui re-established Wu commandery.
In 758. Wu commandery was once more renamed Suzhou.
Wu commandery ceased to exist nominally in 758 and continued to exist under the name of Suzhou. Shortly after the An Lushan Rebellion, the imperial court of Tang enforced heavy taxes on the people of Wu commandery since Wu was not invaded by An's army. However, the tax collection became unbearable for the ordinary peasants of the commandery (An amount of tax that was equivalent to 8 years of laboring was demanded). In 762, a low rank officer of Taizhou, Yuan Chao, with angry peasants, stormed and attacked cities of Wu commandery including Suzhou. The Tang court had to pacify Yuan's unexpected rebellion in 763. Yuan was captured by general Li Guangbi and was escorted to the capital Chang'An. He was soon executed under the charge of treason.

## Functionaries

According to the bureaucratic system of Han dynasty, every commandery has an identical hierarchy of functionaries.
The top administrator of Wu commandery is Taishou(the top official of a Commandery). In addition, the Taishou has a subordinate Juncheng (vice Taishou and an assistant of its work). Military affairs are entrusted to the Duwei of a commandery. In terms of counties, Ling (an officer) is in charge of a county with more than 10 thousand registered families or households. Zhang (an officer) is in charge of a county with a population that is less than 10 thousand.
In Wu commandery, many counties reached a relatively large population, thus were governed by a Ling. Numerous resources proved Wu, Wucheng, Yuhang, Qu'e, Haiyan, Fuchun, Jiaxing, Yangxian to be some of the large counties with a Ling.
During Jin and Southern dynasties, the top official of commanderies (including Wu commandery) were called Neishi. The Neishi, in practice, did not differ from Taishou in any manner.

## Society

Wu was the home of the four clans of Wu (吳郡四姓) . In Eastern Wu, the four clans were pillars of Emperor Sun Quan's rule. Wu and Huai-si region's lords together formed two main power blocs of Eastern Wu.
Lu Yun, a nobleman of Wu commandery in Jin dynasty, described his native commandery as a culturally and politically advanced region comparable with Zhongyuan. His assertion was validated by the fact that in the records of the three kingdoms, 28 individuals from Wu commandery were biographized making Wu the most prolific source of historically important figures during the three kingdom period.
In Han dynasty, Wu had become known for its economic wealth. The 3rd century intellectual Zuo Si had written a rhymed prose concerning Wu commandery. Through his prose, researchers had discovered Wu's prosperous agriculture. On the other hand, Chen Shou's records indicated a flourishing commercial society in 3rd century Wu commandery.
During the rule of Eastern Wu, the government planned military-led plantations in Wu commandery. The aim was to provide a logistic base for the armies on the mission of border defense (against Cao Wei).
The Disaster of Yongjia forced numerous northern nobles to flee from their homeland in central plain. These northern lords later settled down in Wu, Kuaiji and other southern commanderies. However, the native four clans' economic, political and social hegemony in Wu was not threatened by Northern immigrants during Jin dynasty.
