The House of Habsburg-Lorraine is a European royal family that emerged in the 18th century. It was formed through the marriage of Maria Theresa, the last of the Habsburg dynasty, and Franz I, Holy Roman Emperor of the Lorraine family. This union combined the vast Habsburg territories with the Duchy of Lorraine, creating a powerful political entity in Europe. The Habsburg-Lorraine family played a significant role in European history, producing many notable rulers, including Marie Antoinette and Emperor Franz Joseph I. Their influence extended across various regions, including Austria, Hungary, and Bohemia, shaping the political landscape of Europe for centuries.
