- On Saturday, HM King Frederik X began his reign as Denmark's monarch and head of state.
- He succeeds his mother, Margrethe II, after her surprise abdication announcement on New Year's Eve.
On Saturday, Denmark proclaimed Crown Prince Frederik, their new king.
His mother, Queen Margrethe II, had announced in a surprise New Year's message that after reigning for 52 years as monarch, she would abdicate the throne.
"I will step down as Queen of Denmark. I will hand over the throne to my son, Crown Prince Frederik," Margrethe said.
Denmark has one of the oldest monarchies in Europe but ceased the practice of coronations over a century ago.
That meant that, compared to Britain's lavish crowning of King Charles last May, the Danish king assumed the throne in a simple ceremony.
At 2 p.m., the Queen signed a declaration of abdication during a cabinet meeting held at Christiansborg Palace in central Copenhagen. With her signature, the crown formally passed to Frederik.
One hour later, Denmark's Prime Minister Mette Frederiksen stepped onto the palace's balcony to publicly proclaim him king to the thousands who had witnessed the historic moment.
