Victoria Eugenie Julia Ena of Battenberg was Queen of Spain as the wife of King Alfonso XIII from their marriage on 31 May 1906 until 14 April 1931, when the Spanish Second Republic was proclaimed. A Hessian princess by birth, she was a member of the Battenberg family, a morganatic branch of the House of Hesse-Darmstadt. She was the granddaughter of Queen Victoria. Unlike other members of the Battenberg family, who were accorded the lower rank of Serene Highness, Victoria Eugenie was born with the rank of Highness due to a Royal Warrant issued in 1886 by Queen Victoria.
