Archduke Anton of Austria, Prince of Tuscany (Anton Maria Franz Leopold Blanka Karl Joseph Ignaz Raphael Michael Margareta Nicetas von Habsburg-Lothringen; Vienna, 20 March 1901 – Salzburg, 22 October 1987) was a possible Carlist-Carloctavismo pretender to the Spanish throne[1] and an Archduke of Austria by birth.

In 1919, all titles of nobility and royalty were prohibited and outlawed in Austria (while in Hungary they were restored in 1927 and the aristocratic House of Magnates continued until 1945).

After the coup d'état, and the end of Romania's alliance with Germany on 23 August 1944, the family and their servants were in danger of being interned or thrown out of the country, as German citizens.

It was only when King Michael I abdicated on 30 December 1947 and was forced to leave the country that Archduke Anton's family also went into exile.

While Ileana became a nun, Archduke Anton moved to Austria, where he lived until his death in Emmerberg and in St. Lorenz am Mondsee in the Villa Minola.
