Ingrid Victoria Sofia Louisa Margareta (March 28, 1910 - November 7, 2000) was Queen of Denmark from 1947 to 1972 as the wife of King Frederik IX.
Ingrid was born into the House of Bernadotte as the third child and only daughter of Crown Prince Gustaf Adolf of Sweden (later King Gustaf VI Adolf) and his first wife, Princess Margaret of Connaught. In 1920, when she was just ten years old, her mother died from sepsis while in the eighth month of her sixth pregnancy. After her mother's death, Ingrid spent several months of each year in the United Kingdom in the care of her grandfather. In 1935, shortly before her 25th birthday, she married Frederik, then Crown Prince of Denmark. The couple had three daughters: Margrethe, Benedikte, and Anne-Marie.
In 1947, she became queen consort as her husband Frederik became king upon the death of his father, King Christian X. As queen, Ingrid reformed the traditions of Danish court life, abolished many old-fashioned customs at court and created a more relaxed atmosphere at official receptions.
In 1972, Frederik died and was succeeded by his and Ingrid's eldest daughter, Margrethe II. Ingrid was widowed at the age of 61 and assumed a position as family matriarch. Ingrid died in 2000 with her three daughters and ten grandchildren at her bedside. She was 90 years old. As a Swedish Princess with close ties to England, Ingrid becomed a dynamic Queen Consort of Denmark. She is remembered as the queen that helped modernise the royal family of her adopted homeland, the oldest royal house in Europe.
