河西四郡 / Hexi Four Commanderies (Late Han)
河西四郡 / Hexi Four Commanderies enters the wiki through Hanji 979 as the northwest commandery group that requests separation from Liangzhou. The source identifies the group as Dunhuang, Jiuquan, Zhangye, and Wuwei.
The episode’s significance is administrative rather than territorial conquest. The commanderies are too far from the Liangzhou office, and road disorder makes ordinary governance impractical, so the court creates 雍州 and appoints 邯郸商 as inspector. The page stays distinct from 河西 because this is a late-Han provincial-administration issue, not the Warring States Wei-Qin frontier.
