Louise Alexandra Marie Irene Mountbatten (13 July 1889 – 7 March 1965) was Queen of Sweden from 29 October 1950 until her death in 1965 as the wife of King Gustaf VI Adolf. Born a princess of the German House of Battenberg, Louise was closely related to the ruling families of Britain as a great-granddaughter of Queen Victoria and Russia as a niece of the Empress of Russia. During the First World War, Louise served as a nurse in the Red Cross. She married the widowed Gustaf Adolf in 1923 and assumed the role of Sweden's first lady but did not become queen until his accession in 1950. Queen Louise was noted for her eccentricity and progressive views.
