Her Majesty, Queen Margrethe II of Denmark
Queen Margrethe II ascended the Danish throne on January 14, 1972, following the death of her father, King Frederick IX. Her father's younger brother, Prince Knaud, would have been the country's King if Salic law was not abolished. The law on succession was changed after becoming clear that Queen Ingrid could no longer give the country a male heir after having three daughters: Princess Margrethe, Princess Benedikte and Princess Anna Marie who married the future King Constantine II of Greece in early 60's.

Queen Margrethe II is the first female monarch of Denmark. According to its official website, celebrating 40 years on the Danish throne is an extremely rare event in Denmark because most of its monarchs did not live long to see their accessions reached a 40-year-mile. Margrethe is the 52nd Danish monarch and the fourth sovereign to reach the 40th jubille on the throne after King Gorm the Old, King Christian VII and King Christian IX (popularly called the grandfather of all Europe because almost all present-day royals in Europe are his direct descendants).

On Saturday, January 14, Queen Margrethe II and her sisters, Princess Benedikte and Queen Anna Marie, laid a wreath at the tomb of their parents, King Frederick IX and Queen Ingrid (a great granddaughter of Queen Victoria of England) at the Roskilde Cathedral. They were joined later by the rest of the royal family members attending the solemn ceremony celebrating the 40th jubilee of the Queen.
