Conquest Commandery Transition / 灭国后的郡县化过渡

Conquest commandery transition / 灭国后的郡县化过渡 is the process 《资治通鉴·秦纪》118-2｜吃瓜了！王室的瓜 包甜！ identifies after 秦国 destroys 楚国. The episode says Qin first sets the newly conquered Chu region as a temporary Chu commandery, then later divides it into Jiujiang, Zhang, and Kuaiji commanderies.

The concept links battlefield victory to administrative conversion. A state can be defeated, its king captured, and its last resistance extinguished, but the conqueror still has to classify territory, break old political identity into governable units, and fit the region into the commandery-county order.

It also clarifies why Chu’s fall is bigger than a single capital capture. Chu had a large southern territorial base and long political memory, so Qin’s commandery transition is both a governance solution and a way to reduce the possibility that old Chu space remains a coherent resistance platform.

《资治通鉴·秦纪》119-3｜历史上第一位真正意义上“垂帘听政”太后 extends the concept southeastward. After 王翦 pacifies Jiangnan and subdues 百越, Qin establishes 会稽郡. The episode treats this as administrative expansion into the old Wu-Yue region while cautioning that deeper Lingnan incorporation comes later.

《资治通鉴·秦纪》123-2｜古代时期的“倒插门”到底有多危险 supplies the later Lingnan incorporation. Qin’s 214 BCE southern campaign turns 百越 territory into 桂林郡, 南海郡, and 象郡, then uses convict migration to guard and settle the new frontier. The concept therefore now covers post-unification frontier conquest as well as the earlier defeated-state commandery conversion.

《资治通鉴·秦纪》120-3｜揭秘秦始皇为何发明郡县制 turns the transition into an empire-wide settlement. Once Qin has taken all six states, 王绾 still proposes princely fiefs for far former Yan, Qi, and Chu regions, but 李斯 and 嬴政 / 秦始皇 reject that route. The concept therefore leads into 郡县制反分封定局: conquered regions are not merely classified as commanderies after campaigns, but kept from becoming new hereditary states.

《资治通鉴·秦纪》120-4｜并六国后 秦始皇教你如何守江山 adds the local-resistance problem inside that transition. The episode says Qin forcibly relocates powerful households away from conquered regions, then lets local governments push the new management model with fewer old elite networks in place. This makes commandery transition a social conversion as well as an office map.

Key Claims

• Conquest is incomplete until captured territory is translated into legible administrative units.
• Temporary commandery naming can preserve the defeated state’s regional label while preparing later subdivision.
• Subdivision reduces the old state’s political coherence and makes taxation, appointment, transport, and military control easier to standardize.
• The process extends 秦国行政标准化 from reform inside Qin to rule over conquered states.
• Kuaiji shows that post-conquest commandery conversion also applies to southern frontier regions, not only to the defeated royal capitals.
• Qinji 123-2 extends the southern branch beyond Kuaiji into Lingnan commanderies, pairing conquest with convict settlement and marginal-status mobilization.
• Qinji 120-3 shows the final policy choice: commandery conversion becomes the alternative to re-enfeoffing conquered territory under imperial sons.
• Qinji 120-4 adds that commandery conversion can be paired with elite relocation to reduce local resistance before the new government model is imposed.
