Marie Anne of Austria was an Archduchess of Austria as the daughter of Franz II, Holy Roman Emperor and his second wife, Maria Theresa of Naples and Sicily. She never married or had any children due to her being intellectually disabled with a severe facial deformity and having to spend the rest of her life in Hetzendorf Palace.

Francis II and I was the last Holy Roman Emperor as Francis II from 1792 to 1806, and the first Emperor of Austria as Francis I from 1804 to 1835. He was also King of Hungary, Croatia and Bohemia, and served as the first president of the German Confederation following its establishment in 1815.
