Frederik X has officially been crowned King of Denmark, with his wife becoming Queen Mary following the abdication of Queen Margrethe II.
Margrethe became the first Danish monarch to relinquish the throne in almost 900 years. She will retain the title of Queen while Frederik's wife becomes Queen Mary.
Born in Australia, Mary is the youngest daughter of Scottish academics John Dalgleish Donaldson and Henrietta Clark Donaldson (née Horne), who grew up in Port Seton, East Lothian and emigrated to Australia shortly after marrying in 1963. Mary and Frederik were married in 2004 and with Frederik's ascension to power, their eldest son, Christian, 18, will become Crown Prince and heir to the throne.

8. The Queen established charity, The Mary Foundation
The Mary Foundation was established by the Queen of Denmark in 2007. It looks to tackle social isolation in three areas: bullying and well-being, domestic violence and loneliness. The Queen looks to emphasise that everyone has a right to community, and as such supports those who are particularly vulnerable or exposed. She also advocates for women’s reproductive rights, maternal health, sexual and reproductive rights in developing countries as well as international LGBTQ+ rights. | Ritzau Scanpix/AFP via Getty Ima
