       Her father Karl is also the grandson of the last Austro-Hungarian emperor, Charles I, who succeeded Franz Joseph to the imperial throne following his death in 1916 and was formally dethroned in 1919 by the Austrian Parliament.

       The Archduke is a politician, who has focused much of his career on protecting cultural heritage from threats such as armed conflict and natural disasters.

       Since 1986, he has been president of the Austrian branch of the Paneuropean Union and was an MEP for the Austrian People's Party between 1996 and 1999.
