Campaigner Against Duelling
Alfonso Carlos spent most of the rest of his life in Austria where he owned castles at Puchheim and at Ebenzweier near Altmünster, and a house in the Theresianumgasse in Vienna. He devoted himself to the abolition of duelling. In order to gain popular support, he wrote a book on the topic in French (translated into German), and several journal articles in English. He used his wide social contacts to encourage the establishment of anti-duelling leagues in the German Empire (with his wife's uncle Charles, 6th Prince of Löwenstein-Wertheim-Rosenberg, as President), France, Austria, Italy (under the patronage of King Victor Emmanuel II), Hungary, Belgium, and Spain (with King Alfonso XIII as Honorary President).
