 Born Prince Ingolf of Denmark (Danish: "Prins Ingolf Christian Frederik Knud Harald Gorm Gustav Viggo Valdemar Aage til Danmark" ), he appeared likely to some day become king until the constitution was changed in 1953 to allow females to inherit the crown, placing his branch of the dynasty behind that of his cousin Princess Margrethe and her two younger sisters.

 However, through his mother, he is a legitimate descendant of King George II of Great Britain, and retains a place in line to the British throne.
The Treaty of Westminster was a treaty of neutrality signed on 16 January 1756 between Frederick the Great of Prussia and King George II of Great Britain, Elector of Hanover.
