She is the eldest child of King Frederik IX and Queen Ingrid. She became heir presumptive to her father in 1953 when a constitutional amendment allowed women to inherit the throne. In 1967 she married Henri de Laborde de Monpezat, with whom she had two sons, Frederik and Joachim. Margrethe succeeded her father upon his death in January 1972.

Frederik is the eldest son of Queen Margrethe II and Prince Henrik. He was born during the reign of his maternal grandfather, King Frederik IX, and became Crown Prince of Denmark following his mother's accession in 1972. He received his early education privately at home and later attended Krebs School, École des Roches, and Øregård Gymnasium. He earned a Master of Science degree in political science from Aarhus University. After university, he served in diplomatic posts at the United Nations and in Paris, and he has trained in all three branches of the Danish Armed Forces.
