Kungnaebu (Korean: 궁내부; Hanja: 宮內府; lit.
Department of the Royal Household) was a government office of Joseon and the Korean Empire in charge of affairs related to the royal House of Yi.
It had several subdivisions such as Jonchinbu, and Uibinbu, Donnyeongbu and others, some of which were independently operated or belonged to Yukjo (Six Ministries of Joseon).
[3] The current Cultural Heritage Administration of the Republic of Korea claims descent from the Kungnaebu.
Uibinbu took care of dealing with affairs regarding a son-in-law of the king, while Donnyeongbu managed affairs for cultivating mutual friendship among relatives of the king and queen.
