Danish and Swedish Princess, Oldenburg Dynasty. 20th century legal spelling of name. Duchess of West Gothland, consort of Prince Carl, thus Princess of Sweden and (until 1905) also of Norway. Second daughter and fifth child of Crown Prince Frederick of Denmark. Her mother was originally Princess of Sweden, the only surviving child of King Carl XV of Sweden, Carl IV of Norway. Married 1897 in Copenhagen to Prince Carl of Sweden, her first cousin. In 1947 on their Golden Wedding Anniversary, her spouse admitted that their marriage had been completely arranged by their respective fathers, and Ingeborg herself added: "I married a complete stranger!". It was a popular marriage because of her Swedish heritage. For her first 10 years in her new home country, when Queen Sofia of Sweden seldom attended public events and Crown Princess Viktoria spent most of her time abroad for health reasons, Princess Ingeborg had many duties, unofficially performing much of the role associated with the queen consort. She performed those duties with dignity and easygoing friendliness and wit. Ingeborg was interested in sports, especially ice skating, and at the automobile exhibition of Stockholm of 1903, she and Crown Prince Gustaf spontaneously demonstrated a new car from Scania. She and Carl lived an informal and intimate family life with their children. In 1922 a bank crashed and they had to sell their home. In 1905 the Norwegian government had discussed making them King and Queen of Norway, but Carl declined the offer and her brother was elected King Haakon VII of Norway. Ingeborg's kinship to the Scandinavian dynasties helped bring the three royal houses together again after tension created due to Norway's 1905 secession from the union with Sweden. During World War II she blocked the window of her house facing the German Embassy in Stockholm. Princess Ingeborg was the grandmother of three European monarchs, King Harald V of Norway, King Baudoin of Belgium and his brother King Albert II, as well as great-grandmother of two: Henri, Grand Duke of Luxembourg and Philippe, King of the Belgians.
