巴蜀 / Ba-Shu

巴蜀 / Ba-Shu enters the wiki through 《资治通鉴·周纪》52丨 陈庄叛秦 端起碗吃饭放下碗骂娘 as the combined regional prize after 秦国 intervenes in the conflict between 巴国 and 蜀国. The episode describes the region as hard to enter and valuable enough that local control can tempt a governor toward independence.

The source emphasizes two layers of value. First, terrain creates defensive confidence: if Qin cannot easily enter, an ambitious local figure can imagine holding the region. Second, agricultural value makes the prize worth seizing, especially in the later frame where 都江堰 under 李冰 helps make Shu a major food source for Qin.

Ba-Shu therefore anchors both Qin’s strategic gain and 陈庄’s miscalculation. The same region that feeds Qin also makes delegated local authority dangerous if the central state cannot supervise it.
