Prince Viggo, Count of Rosenborg (Viggo Christian Adolf Georg; 25 December 1893 – 4 January 1970) was a Danish prince. He was born in Copenhagen the youngest son of Prince Valdemar of Denmark and Princess Marie of Orléans. He was also the youngest grandson of Christian IX of Denmark.
Prince Viggo was born on 25 December 1893, in the Yellow Palace, an 18th-century town house at 18 Amaliegade, immediately adjacent to the Amalienborg Palace complex in Copenhagen.[1] He was the fourth child of Prince Valdemar of Denmark, and his wife Princess Marie of Orléans.[2] His father was a younger son of King Christian IX of Denmark and Louise of Hesse-Kassel, and his mother was the eldest daughter of Prince Robert, Duke of Chartres and Princess Françoise of Orléans. His parents' marriage was said to be a political match.[3]
He was christened on 24 February 1894 and his godparents were: King Christian IX and Queen Louise of Denmark (his paternal grandparents); Prince Christian of Denmark (his paternal first cousin); Prince George of Greece and Denmark (his paternal first cousin); Grand Duke Adolphe and Grand Duchess Adelheid-Marie of Luxembourg; Anna, Landgravine of Hesse; and Princess Marie of Anhalt. He was an Officer.[4]
Without the legally required permission of the Danish king for a dynastic marriage,[5] Viggo married Eleanor Margaret Green (New York City, 5 November 1895 – Copenhagen, 3 July 1966), in New York City on 10 June 1924.[6]
As became customary in the Danish royal house upon marriage to a commoner, prior to the wedding Viggo renounced his place in Denmark's line of succession to the Crown, forfeiting his title of Prince of Denmark, and his style of Royal Highness.[7] With the king's authorisation, he assumed the title "Prince Viggo, Greve af (Count of) Rosenborg" and the style of Highness on 21 December 1923.[7] Although the comital title was made hereditary for all of his legitimate descendants in the male line, the princely title was restricted to himself and his wife alone (i.e. "Prince and Princess Viggo", etc.).[7] The couple had no children.
Prince Viggo died in Ebeltoft in 1970. He was the last surviving grandson of Christian IX.
