Elisabeth (Elisabeth Amalie Eugenie; German: [eˈliːzaˌbɛt aˈmaːliə ɔʏˈɡeːniə]; 24 December 1837 – 10 September 1898), nicknamed Sisi or Sissi, was Empress of Austria and Queen of Hungary from her marriage to Franz Joseph I on 24 April 1854 until her assassination in 1898.
Elisabeth was born into the Bavarian House of Wittelsbach but enjoyed an informal upbringing before marrying her first cousin, Emperor Franz Joseph I, at 16. The marriage thrust her into the much more formal Habsburg court life, for which she was unprepared and which she found suffocating. The couple had four children: Sophie, Gisela, Rudolf, and Marie Valerie. Early in her marriage, Elisabeth was at odds with her aunt and mother-in-law, Archduchess Sophie, who took over the rearing of Elisabeth's children. The birth of a son, Rudolf, improved Elisabeth's standing at court, but her health suffered under the strain. As a result, she would often visit Hungary for its more relaxed environment. She came to develop a deep kinship with Hungary and helped to bring about the dual monarchy of Austria-Hungary in 1867.
