Franz Joseph I of Austria bestowed upon August and his descendants the style of
Hoheit ("
Highness"), a higher style in Germany than
Durchlaucht ("
Serene Highness"), which
Ernestine princes were usually entitled to. The reason for the grant was that eight days later
Princess Stéphanie of Belgium (younger sister of August's daughter-in-law
Louise) was to marry Franz Joseph's son
Crown Prince Rudolf; Franz Joseph considered it appropriate that his son's in-laws have a higher rank at the Austrian court. == Honours ==
