Ingrid was born on 28 March 1910, at the Royal Palace in Stockholm as the third child and the only daughter of Gustaf Adolf, Crown Prince of Sweden and his first wife, Princess Margaret of Connaught.

Her mother was a daughter of Queen Victoria's third son Prince Arthur, Duke of Connaught and Strathearn by his wife Princess Louise Margaret of Prussia.

She was baptised Ingrid Victoria Sofia Louisa Margareta in Slottskyrkan (the Royal Chapel) in Stockholm, Sweden on 5 May 1910.

[citation needed] Crown Princess Margaret founded a school for Ingrid with a small circle of Swedish noble girls.

She often played tennis against her grandfather King Gustav V. During her young adulthood, Ingrid was often seen driving her two-seat car around Stockholm.

[6] Her mother, Margaret of Connaught, and the then-Prince of Wales' father, King George V, were first cousins, both being grandchildren of Queen Victoria.

Ingrid wore the veil of Irish lace her late mother, Princess Margaret of Connaught, had worn at her wedding 30 years earlier.

She wore a crown of myrtle from a shrub her mother had brought with her from Osborne House in England to Sofiero Palace in Sweden.

Her open defiance of the occupation forces made her grandfather, King Gustav of Sweden, worry about the risks, and in 1941, he sent a demand to her to be more discreet "for the sake of the dynasty" and its safety, but she reacted with anger and refused to obey, and she had the support of her spouse, who shared her views.

One display of defiance shown by Ingrid was her positioning of the flags of Denmark, Sweden and the United Kingdom in the window of the nursery at Amalienborg, the royal residence in the centre of Copenhagen.

That same year, after having sworn to respect the Danish constitution, she was appointed Rigsforstander (formal regent) and representative of the monarch whenever her daughter (and later her grandsons) were absent, a task she performed on many occasions.

She was patron of a long line of social organizations, positions which, one after another, she eventually left to Princess Benedikte as years passed: Røde Kors, Ældre Sagen, Red Barnet, Løgum Klosters Refugium, and Fonden for Træer og Miljø.

Grønlandsfond, and Dronning Ingrids Romerske Fond til støtte af kulturelle og videnskabelige formål.

Thousands gathered outside Amalienborg Palace, her official residence, after her death was announced; flowers were left, candles were lit and hymns were sung in her honour.

[10] Her funeral took place on 14 November 2000, and Ingrid was interred next to her husband, King Frederik IX, outside Roskilde Cathedral near Copenhagen.
