In 1972 she became the first female monarch of Denmark since Margaret I, ruler of the Scandinavian countries in 1375-1412 during the Kalmar Union.Princess Margrethe was born on 16 April 1940 at Amalienborg Palace in Copenhagen. Her parents were the future Frederik IX and Ingrid of Sweden, then Crown Prince and Crown Princess of Denmark.She was baptised on 14 May 1940 in the Church of Holmen. Since her paternal grandfather, the then-reigning King Christian X, was also the King of Iceland at the time, as a tribute to the people of Iceland, the Princess was given an Icelandic name, Þórhildur (spelled with the Icelandic thorn character, simplified as "th"). This middle name is sometimes anglicized as "Thorhildur."
