Reign
Queen Margrethe II announced her abdication during her annual live broadcast New Year's Eve address on 31 December 2023. Frederik succeeded her as King of Denmark on 14 January 2024, after Margrethe formally signed an instrument of abdication during a meeting of the Council of State.After succeeding to the throne, he was proclaimed king from the balcony of Christiansborg Palace by Prime Minister Mette Frederiksen as has been the custom for Danish monarchs since the introduction of the constitutional monarchy in 1849. His motto is Forbundne, forpligtet, for Kongeriget Danmark, the first motto that does not mention God since Frederik VII.
On 15 January, the royal family appeared in Parliament for a ceremony marking the transition of head of state. On 21 January, the royal family attended a celebratory church service at Aarhus Cathedral, led by the Bishop of Aarhus and Royal Chaplain-in-Ordinary, Henrik Wigh-Poulsen.
On 31 January 2024, Frederik visited Poland and was received by its president Andrzej Duda, in his first overseas trip as monarch. Danish monarchs traditionally travel first to another Scandinavian country, but Frederik had planned the trip prior to Margrethe's abdication.
The King and Queen made their first state visits in May 2024, visiting Sweden and Norway. In June, they toured Greenland, one of the autonomous territories of the Kingdom of Denmark. Their planned tour of the Faroe Islands was postponed due to workers' strikes. The tour is now scheduled for 2025.
In November 2024 the Royal Court announced that the King had decided to phase out the system of granting companies royal warrants, which has been extant in Denmark since the 19th century. The motivation was that a system in which companies can claim special recognition from the royal house was not in keeping with the times. All warrants and similar titles are to be phased out by 31 December 2029.
In January 2025, when U.S president elect Donald Trump renewed talks about the intended U.S purchase of Greenland, the King made a speech promoting unity and collaboration within the Kingdom of Denmark. He also issued a royal decree to update the royal coat of arms from his mother's 1972 design. The changes included increasing the sizes of the symbols of Greenland and the Faroe Islands to make them more prominent. The new design “strengthens the prominence of the Commonwealth in the royal coat of arms,” according to a statement made by The Royal House on 1 January 2025.
