Reign
Duke Wen succeeded his father Duke Xiang of Qin, who died in 766 BC while campaigning against the Quanrong in Qishan. He moved the Qin capital back to Quanqiu from Qian, but in 762 BC moved the capital again to the confluence of the Qian and Wei rivers.In 753 BC Duke Wen established the office of historiographer to record the official history of Qin. In 750 BC he defeated the Rong tribes that were occupying the former Zhou land. He returned the territory east of Qishan to Zhou, and kept the rest for Qin as King Ping of Zhou had promised Duke Wen's father Duke Xiang that Qin could keep the land west of Qishan if they could expel the Rong people. By repelling the Rong, the territory of Qin was greatly expanded.
