长沙郡 / Changsha Commandery (late Han)
长沙郡 / Changsha Commandery enters the late-Han wiki branch through Hanji 1027 as the southern 荆州 commandery governed by 张献. This page is disambiguated from the modern Changsha city page and from 长沙国 in the early Western Han branch.
In the source, Changsha matters as a local-power base rather than as a city profile. Higher taxation and tension with 刘表 give 桓阶 room to advise Zhang Xian to combine Changsha with 零陵郡 and 桂阳郡, then attach to 曹操. The commandery therefore becomes the lead node in southern Jingzhou’s breakaway.
