Princess Ingeborg was born on 2 August 1878 at her parents' country residence, the Charlottenlund Palace north of Copenhagen, during the reign of her paternal grandfather, King Christian IX.

[1] As a granddaughter of Christian IX, referred to by the sobriquet the "Father-in-law of Europe", Princess Ingeborg was related to several European monarchs and rulers.

[4] Under the supervision of their mother, the children of the Crown Princess received a rather strict Christian-dominated upbringing, which was characterized by severity, the fulfillment of duties, care and order.

It had long been a public secret that Crown Princess Louise wanted one of her daughters to marry a member of the Swedish royal family, which thus indeed happened.

[1] The wedding guests included members of the Danish and Swedish royal families, as well as the bride's paternal aunts, the Dowager Empress of Russia and the Princess of Wales.

After the wedding reception, the newly married couple left the palace for the pier, where they embarked the Danish royal yacht, the paddle steamer Dannebrog, which early next morning sailed for Lübeck.

"[11] Ingeborg was interested in sports, especially ice skating, and at the automobile exhibition of Stockholm in 1903, she and the Crown Prince, Gustav, made a spontaneous demonstration trip in a car from Scania.

"[10] During World War II from 1940 to 1945, she demonstrated publicly against Nazi Germany by blocking the window of her house which faced the German embassy in Stockholm.
