Researches on Manchu Origins

Researches on Manchu Origins, also known as Manzhou Yuanliu Kao, is an important history book published by the Qing Dynasty government in 1777. The Qianlong Emperor sponsored its compilation with the goal of legitimizing Qing rule, as well as identifying the Qing as a successor to the Jin Dynasty (1115–1234). The Manzhou Yuanliu Kao also bolstered Qianlong's conception of the Manchu people as a "wu", or martial race.
It consists of 4 parts: Manchu tribes, territory, topography (mountains and rivers), and culture. Pamela Kyle Crossley analyses it as the apex of the Qing Dynasty's attempt at "documentary institutionalisation" of Manchu heritage and from it, Manchu ethnic identity. Researches on Manchu Origins contained a list of corrections of transcribed Jurchen language words found in the History of Jin in Chapter 135, using the Manchu language to correct them, in Chapter 18.
