She cited health reasons after she underwent major back surgery last February.
Danish royal expert Thomas Larsen said: “The Queen has been here and has been on the throne for more than 50 years. She is a very respected and popular person, so people did not expect this and were in a state of shock.”
Karin Holke Jepsen, 31, a communications consultant who traveled to Copenhagen for the royal event, said: “I was shocked and started crying when the queen said on New Year's Eve that she would abdicate.
“It's very rare to witness a real historical moment that you know is going to be written about in the history books.”
The abdication of the throne comes 52 years after Margaret ascended the throne following the death of her father, King Frederick IX.
