Imperial Highness
Imperial and Royal Highness (abbreviation HI&amp;RH) is a style possessed by someone who either through birth or marriage holds two individual styles, "Imperial Highness" and "Royal Highness". "His/Her Imperial Highness" is a style used by members of an imperial family to denote "imperial" – as opposed to "royal" – status to show that the holder is descended from an Emperor rather than a King or Queen. Holders of the style "Imperial Highness" generally rank above holders of the style "Royal Highness".
