He was the son of King Christian X of Denmark and Queen Alexandrine, born Duchess of Mecklenburg, and the fourth Danish monarch of the House of Glücksburg.

The Kingdom of Denmark (Danish: Kongeriget Danmark, pronounced [ˈkɔŋəʁiːəð ˈdanmɑɡ̊] ( listen)) is a constitutional monarchy and sovereign state consisting the country of Denmark in northern Europe and two autonomous constituent countries, the Faroe Islands in the North Atlantic and Greenland in North America. The kingdom is a unitary state with some power being devolved from Denmark proper to Greenland and the Faroe Islands; this polity is referred to as the Danish Realm. Denmark proper is the hegemonial area, where judicial, executive, and legislative power resides. The Faroe Islands are defined to be a community of people within the kingdom, and the Greenlandic people are defined as a separate people with the right to self-determination.

Denmark is the southernmost of the Nordic countries, located southwest of Sweden and south of Norway, and bordered to the south by Germany. The country consists of a large peninsula, Jutland and many islands, most notably Zealand, Funen, Lolland, Falster and Bornholm, as well as hundreds of minor islands often referred to as the Danish Archipelago.

Ingrid of Sweden (Ingrid Victoria Sofia Louise Margareta; 28 March 1910 – 7 November 2000) was a Swedish princess and the queen consort of King Frederick IX of Denmark.

She was born in Stockholm the third child of King Gustaf VI Adolf of Sweden and his first wife, Princess Margaret of Connaught. She also was a great-granddaughter of Queen Victoria of the United Kingdom. Ingrid's mother died in 1920 while carrying her sixth child. Her father married Lady Louise Mountbatten three years later. Louise was a second cousin of Ingrid's. There were no children of this second marriage, only a stillborn daughter. Ingrid was raised to a sense of duty and seriousness. She had a difficult time after her father remarried.

In 1928, Ingrid met the Prince of Wales and was seen by some as a possible wife for the heir-apparent to the British throne, who was her second cousin. Her mother, Margaret of Connaught, and the then-Prince of Wales' father, King George V, were first cousins, both being grandchildren of Queen Victoria. However, no engagement took place.

Princess Benedikte of Denmark, Princess of Sayn-Wittgenstein-Berleburg, RE, SKmd (born Princess Benedikte Astrid Ingeborg Ingrid of Denmark), (born 29 April 1944), is the second daughter of King Frederick IX of Denmark and Ingrid of Sweden. She is the younger sister of the reigning Queen of Denmark, Margrethe II, and the older sister of Queen Anne-Marie of Greece.

Her godparents were the King and Queen of Denmark, Prince Gustav of Denmark, the King of Sweden, Count Sigvard Bernadotte af Wisborg, Sir Alexander Ramsay, the Queen of the United Kingdom, Princess Caroline-Mathilde of Denmark, Princess Margaret of Denmark, and Princess Ingeborg of Sweden.

Benedikte was married on 3 February 1968 at Fredensborg Palace Church to Richard, 6th Prince of Sayn-Wittgenstein-Berleburg, born in Giessen on 29 October 1934. He is the son of Prince Gustav Albrecht, 5th Prince of Sayn-Wittgenstein-Berleburg (1907–1944) and his wife, Margareta Fouché (1909–2005). The King decreed that her children would need to be raised in Denmark in order to have succession rights. Since the condition was not met, Princess Benedikte's three children are not in line to succeed to the throne
