As the eldest child of King Frederik IX and Ingrid of Sweden, she succeeded her father upon his death on 14 January 1972. On her accession, she became the first female monarch of Denmark since Margrethe I, ruler of the Scandinavian countries in 1375–1412 during the Kalmar Union. Having been on the Danish throne for 43 years, she is currently the longest-reigning of the three Scandinavian monarchs (Sweden's Carl XVI Gustaf has reigned since 1973 and Norway's Harald V has reigned since 1991). She is one of two queens regnant currently on the throne along with Queen Elizabeth II. Margrethe was born in 1940, but did not become heir presumptive until 1953, when a constitutional amendment allowed women to inherit the throne (after it became clear that King Frederik was unlikely to have any male issue). In 1967, she married Henri de Laborde de Monpezat, with whom she has two sons: Crown Prince Frederik (born 1968) and Prince Joachim (born 1969).
