Archduchess Isabella of Austria

Archduchess Isabella Maria Theresia Christine Eugenie of Austria-Teschen (17 November 1888 – 6 December 1973) was a daughter of Archduke Friedrich, Duke of Teschen and his wife, Princess Isabella of Croÿ. She was a member of the House of Habsburg-Lorraine (her grandfather, Archduke Karl Ferdinand of Austria, was a grandson of Leopold II, Holy Roman Emperor).

Isabella was notable for her brief marriage to Prince Georg of Bavaria. Their separation and subsequent annulment were widely reported in newspapers. As a result of this and her later actions as a nurse in the Austro-Hungarian Army, Isabella became considered as a romantic figure; one publication called her "the most romantic heroine of the present war in Austria".
