The Imperial Household Department (simplified Chinese: 内务府; traditional Chinese: 內務府; pinyin: Nèiwùfǔ; Manchu: Dorgi baita be uheri kadalara yamun) was an institution of the Qing dynasty of China. Its primary purpose was to manage the internal affairs of the Qing imperial family and the activities of the inner palace (in which tasks it largely replaced eunuchs), but it also played an important role in Qing relations with Tibet and Mongolia, engaged in trading activities (jade, ginseng, salt, furs, etc.), managed textile factories in the Jiangnan region, and even published books.
