Imperial Household Department
The Imperial Household Department (; ) 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. This department was also in charge of the ceremonial and spiritual activities of the Qing imperial household. These activities include the maintenance of the mausoleums of Qing emperors, polytheist worships and posthumous affairs of the royal family (the giving of temple names and posthumous names). Origins
The department was established before the Manchu-led Qing dynasty defeated the Ming dynasty in 1644, but it became mature only after 1661, following the death of the Shunzhi Emperor and the accession of his son, who reigned as the Kangxi Emperor. In 1654, the department was temporarily substituted by the Thirteen Yamen (十三衙門) which had similar functions. In 1661, the thirteen yamen were abolished with the re-establishment of the imperial household department. Personnel
The department was manned by booi (Manchu: booi, ), or "bondservants", who were selected from the bondservants of the upper three banners. Booi was sometimes synonymous with booi aha, which literally means "household person", but aha usually referred to the hereditary and legally servile people who worked in fields, whereas booi usually referred to household servants who performed domestic service. The booi who operated the Imperial Household Department can be divided into roughly four groups:

 a small booi elite; 
 the majority of the booi; 
 indentured servants of the booi; 
 the state bondservants (Manchu: sinjeku, ). In total, there were three nirus of the department consist of booi. They are Cigu Niru (Chinese niru), Solho Niru (Korean niru) and Hoise Niru (Muslim niru) respectively. The demographic composition of the department was thus diverse. Manchu, Han Chinese, Korean and Muslim were cooperating to keep the department functioning. The three nirus of the imperial household department were under the inner three banners out of the Eight Banners system. Various classes of Booi

The central administration of the imperial household department was carried out by its chancery.
