An Austrian Archduchess is a member of the royal family of Austria, specifically the House of Habsburg. This title was historically held by the daughters of the Emperor of Austria, who ruled over the Austro-Hungarian Empire. Archduchesses often played significant roles in European politics through strategic marriages and alliances. The title of Archduchess is distinct from that of a princess, as it signifies a higher rank within the nobility. Notable Austrian Archduchesses include Marie Antoinette, who became the Queen of France, and Elisabeth of Austria, known as Sisi, who was the Empress of Austria and Queen of Hungary.
