Zhangyi Circuit
Zhangyi Circuit (彰义军) was a military circuit (节度使) of the Tang dynasty whose command, in the passages of the Old Book of Tang that name it, was tied to the prefectures of Shenzhou (申州), Guangzhou (光州), and Caizhou (蔡州) in the Huai region. The record shows the title in use during the imperial campaign against Wu Yuanji (吴元济), when the chancellor Pei Du (裴度) held the commission and the civil administration of the circuit passed to Ma Zong (马总) after the victory. Sources disagree over whether the name belonged to this Huai town or to a different northwestern circuit granted the title decades later.

History in the record
The Old Book of Tang records the circuit's title in a sequence of appointments during the Huaixi campaign. In a seventh-month entry, Yuan Zi (袁滋) was transferred from 荆南 to be 唐州刺史、彰义军节度使、申光唐蔡随邓州观察使, with the seat provisionally placed at Tangzhou (唐州) (权以唐州理为所) 1. Because the history describes 袁滋 as a scholar (以滋儒者), Yang Min (杨旻), then prefect of 随州, was made 唐州刺史 and 行营都知兵马使 to command the troops in his place 1.
Later in the same seventh month, the court restructured the command. Pei Du, then 中书侍郎 and 平章事, was made 守门下侍郎同平章事、使持节蔡州诸军事、蔡州刺史, 充彰义军节度、申光蔡观察处置等使, and additionally 淮西宣慰处置使 1. A campaign staff went with him: Ma Zong as 淮西行营诸军宣慰副使, Han Yu as 彰义军行军司马, and Li Zhengfeng (李正封), Feng Su (冯宿), and Li Zongmin (李宗闵) as 判官书记 1. According to the Jiu Tangshu, the edict designated Yancheng (郾城) as the seat of 行蔡州, the forward administration of 蔡州 1.
In the eleventh month, the emperor received the captives of 淮西 at 兴安门. Wu Yuanji was paraded through the two markets and beheaded at Duliushu; his wife Shen Shi (沈氏) entered the palace servitude, his brothers and sons were exiled and soon executed, and seven members of his staff, including Liu Xie (刘协), were executed 1.
Structure and personnel
The circuit's commission in the record combined military and observation authority. 袁滋's commission joined the military commissionership of 彰义军 to an observation commission over six prefectures, 申, 光, 唐, 蔡, 随, and 邓; after the reorganization, 裴度's commission covered 申, 光, and 蔡 1. After the victory, the court created the new prefecture of Yinzhou (溵州) with Yancheng as its seat, attaching Shangcai (上蔡), Xiping (西平), and Suiping (遂平) counties to it 1.
Ma Zong, who had served as 宣慰副使 and then 留后 at 蔡州, was confirmed as 检校工部尚书、蔡州刺史、彰义军节度使、溵州颍陈许节度使 1.
Military style
The record shows the circuit as the command framework for a coordinated imperial campaign rather than as a source of tactics. Field command was separated from the scholar-commissioner: when 袁滋 received the circuit, 杨旻 was given his troops because 袁滋 was a civilian scholar 1. The fighting was carried by regional armies reporting victories to the court, as when 宣武军 announced it had broken the rebels (宣武军奏破贼) 1. After the fall of 淮西, rewards for 破贼功 went to Li Su (李愬), Han Hong (韩弘), Li Guangyan, and Wu Zhongyin (乌重胤), and to subordinate commanders Han Gongwu (韩公武) and Tian Bu (田布) 1.
Political influence
The circuit's political weight in the record comes from the rank of the men the court attached to it. 裴度 held the commissionership while remaining a chancellor (同平章事), combining supreme campaign authority (淮西宣慰处置使) with the circuit command, and the future chief minister Cui Qun (崔群) was appointed 中书侍郎、同中书门下平章事 in the same edict 1. Victory brought recognition: 裴度 received the title 晋国公 with an estate of 3,000 households 1.
Assessment and the disputed name
The identification of the name is disputed. The Old Book of Tang also shows the title attached to the same region before the campaign: 吴少诚 died as 彰义军节度使, and 吴少阳, then 申光蔡节度留后, was later confirmed as 检校工部尚书, 充彰义军节度、申光蔡等州观察使 2. The Old Book of Tang passages naming 彰义军 place the title in the 申光蔡 region during the Huaixi campaign, which supports the identification of the name with the Huai town for the period the record covers 1.
