Illustrious Highness

Style of address / From Wikipedia, the free encyclopedia

His/Her Illustrious Highness (abbreviation: H.Ill.H.) is the usual English-language translation for Erlaucht, a style historically attributed to certain members of the European aristocracy. It is not a literal translation, as the German word for "Highness" is Hoheit, a higher style that appertained to sovereign dukes and other royalty.
