The family played a significant role in European royalty, with connections to various royal houses. The title was created in the late 19th century and was associated with the House of Battenberg. The family later changed their name to Mountbatten during World War I due to anti-German sentiment in Britain. The Duchess and her descendants contributed to the history of European nobility.
