A posthumous name is an honorary name given mainly to revered dead people in East Asian culture. It is predominantly used in Asian countries such as China, Korea, Vietnam, Japan, and Thailand. Reflecting on the person's accomplishments or reputation, the title is assigned after death and essentially replaces the name used during life. Although most posthumous names are given to royalty, some posthumous names are given to honour significant people without hereditary titles, such as courtiers or military generals.
To create a posthumous name, one or more adjectives are inserted before the deceased's title. The name of the state or domain of the owner may be added to avoid ambiguity.
