秦文公 / Duke Wen of Qin
秦文公 / Duke Wen of Qin appears in 《资治通鉴·周纪》10丨 以家族单位 有蚂蚁吃大象的精神（1） at the end of the source’s 秦国 origin digression. The host says Qin had to recover the land granted by 周平王 from the Quanrong and only drove them out by Qin Wen Gong’s generation.
His source role is to show that recognition and actual control are different. Qin may receive status and land claims through 秦襄公, but territorial possession still requires later effort.
