Wife of the Heir of the Thrones of Austria, Hungary, Czechia and Croatia
(as well as Slovenia, Slovakia and Bosnia-Herzegovina). Her
father-in-law altered the Sucession Laws in order to recognize the
marriage (as well as the marriages of some of his relatives) as
dynastic, since before then the marriage of an Hapsburg was only
recognized as equal if contracted with a member of a royal, mediatized
or feudal (old) noble house.
