 Zita occupied her final years with her family . Although the restrictions on the Habsburgs entering Austria had been lifted , this only applied to those born after 10 April 1919 . This meant Zita could not attend the funeral of her daughter Adelheid in 1972 , which was painful for her . She also involved herself in the efforts to have her deceased husband , the " Peace Emperor " canonised . In 1982 , the restrictions were eased , and she returned to Austria after having been absent for six decades . Over the next few years , the Empress made several visits to her former Austrian homeland , even appearing on Austrian television . In a series of interviews with the Viennese tabloid newspaper Kronen Zeitung , Zita expressed her belief that the deaths of Crown Prince Rudolf of Austria and his mistress Baroness Mary Vetsera , at Mayerling , in 1889 , were not a double suicide , but rather murder by French or Austrian agents .
