Elisabeth of Austria (24 December 1837 – 10 September 1898) was the spouse of Franz Joseph I, and therefore both Empress of Austria and Queen of Hungary. She also held the titles of Queen of Bohemia and Croatia, among others. From an early age, she was called Sisi by family and friends.

Although Elisabeth had a limited (though significant) influence on Austro-Hungarian politics, she became a historical icon. The Empress is now thought to have been a non-conformist who abhorred conventional court protocol, as well as a free spirit who valued an individual sense of freedom above anything else. Following the suicide of her son, Rudolf, she withdrew from public life. Her murder by an anarchist in Geneva, Switzerland in 1898 ended the life of a woman who has since become known as an enigmatic and tragic figure.
