Today is the Queen's eightieth birthday and to mark the occasion I have written an essay on the history of Norwegian queens (external link) which appears in Aftenposten, the country's largest newspaper, today.
When Sonja became Queen in 1991, the position had been vacant for 52 years following the death of Queen Maud and therefore she had to carve out the role anew. However, Norwegian history is full of interesting and influential queens, such as Ælfgifu, Astrid Olavsdatter, Margareta Fredkolla, Ingerid Ragnvaldsdatter, Ingeborg Eriksdatter, Margareta Valdemarsdatter, Philippa of England, Blanca of Namur, Dorothea of Brandenburg, Josephine of Leuchtenberg and Sophie of Nassau.
