About Margrethe II
Margrethe II (Danish: [mɑˈkʁeˀtə]; Margrethe Alexandrine Þórhildur Ingrid, born 16 April 1940) is a member of the Danish royal family who reigned as Queen of Denmark from 14 January 1972 until her abdication on 14 January 2024. Having reigned for exactly 52 years, she is the second-longest-reigning Danish monarch after Christian IV. Margrethe was born into the House of Glücksburg, a cadet branch of the House of Oldenburg, during the reign of her paternal grandfather, King Christian X. She is the eldest child of King Frederik IX and Queen Ingrid (born Princess of Sweden). 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. Margrethe has worked as a scenographer, costume designer, and illustrator of works by J. R. R. Tolkien. Support for the monarchy in Denmark, alongside her personal popularity, gradually rose throughout the course of her reign, attaining around eighty per cent by the time of her abdication. She was succeeded by her elder son, Frederik X. Margrethe attended the traditional New Year Courts for the first time in 1956. Princess Margrethe therefore became heir presumptive.
