House of Lorraine
The House of Habsburg-Lorraine () originated from the marriage in 1736 of Francis III, Duke of Lorraine and Bar, and Maria Theresa of Austria, later successively Queen of Bohemia, Queen of Hungary and Archduchess of Austria. Its members are the legitimate surviving line of the House of Habsburg and the House of Lorraine, inheriting their patrimonial possessions and vocation to the Empire from the female descendants of the House of Habsburg and the male line of the House of Lorraine.
