Why was Franz Ferdinand berried higher than his wife?

Archduke Franz Ferdinand of Austria was buried in a higher location than his wife, Sophie, due to the customs and hierarchies of the Habsburg monarchy. As a member of the ruling family, his status dictated a place of honor in the family tomb, while Sophie, although a duchess, held a lower rank due to her marriage into the royal family. This practice reflected the societal norms of rank and privilege during that era.
