陇西郡 / Longxi Commandery
陇西郡 / Longxi Commandery enters the wiki through 《资治通鉴·周纪》85｜宣太后为何私通30年后暗杀了老情人？ as one of the Qin northern frontier commanderies that become strategically meaningful after 秦国 destroys 义渠. The episode says both Longxi and the later 北地郡 came from former Yiqu territory.
Its role in the source is connective. Once Beidi is added, Longxi, Beidi, and 上郡 form a linked Qin defensive belt against northern Hu groups, turning a long-standing rear-frontier threat into administered border depth.
The page is source-scoped until additional episodes develop Longxi independently. Here it supports the 秦国后方边患管理 branch and the episode’s explanation of why eliminating Yiqu mattered to Qin’s wider expansion.
《资治通鉴·秦纪》121｜嬴政造世界最早高速公路 2200年荒草不生 adds Longxi as part of Qin Shi Huang’s first post-unification journey in 220 BCE. The episode reads the route through Longxi and 北地郡 as a westward movement into Qin old lands, likely connected to 高庙礼 at 雍城 rather than to a generic inspection tour.
Hanji 149 part 2 adds the Chu-Han reuse of Longxi after Liu Bang recovers Guanzhong. The episode says Han forces take Longxi after Liu Bang moves his capital to 栎阳, making the old Qin frontier commandery part of Liu Bang’s rear-base consolidation before the eastward contest.
Hanji 155-1 returns to Longxi after 废丘 falls. The episode says Han fully pacifies former Yong territory and sets 中地郡, 北地郡, and Longxi Commandery, making Longxi part of the completed administrative conversion after 章邯’s last position collapses.
Hanji 937 adds a late-Han crisis layer. 韩遂 attacks Longxi after absorbing other Liangzhou rebel forces, and Longxi administrator 李相如 joins the rebellion. In this source, Longxi is a frontier commandery where formal Han administration folds under rebel pressure.
