明史
The change of the name from Jurchen to Manchu was made to hide the fact that the ancestors of the Manchus, the Jianzhou Jurchens, had been ruled by the Chinese. The Qing dynasty carefully hid the two original editions of the books of ""Qing Taizu Wu Huangdi Shilu" and the "Manzhou Shilu Tu"" (Taizu Shilu Tu) in the Qing palace, forbidden from public view because they showed that the Manchu Aisin-Gioro family had been ruled by the Ming dynasty. In the Ming period, the Koreans of Joseon referred to the Jurchen inhabited lands north of the Korean peninsula, above the rivers Yalu and Tumen to be part of Ming China, as the "superior country" (sangguk) which they called Ming China. The Qing deliberately excluded references and information that showed the Jurchens (Manchus) as subservient to the Ming dynasty, from the History of Ming to hide their former subservient relationship to the Ming. The Veritable Records of Ming were not used to source content on Jurchens during Ming rule in the History of Ming because of this.
