Imperial Highness is a form of address used for members of an imperial family. It denotes imperial – as opposed to royal – status to show that the holder in question is descended from an emperor rather than a king. It is typically used to address a prince or princess who is the child of the emperor and/or empress, or their spouse. Used with possessive pronouns such as his, her, or their, the title is abbreviated accordingly as H.I.H. or T.I.H.
