King
Charles III of Great Britain and Northern Ireland is diagnosed with cancer, a
diagnosis which, unusually for a British royal, he is quick to share with the
public. His duties and engagements will be scaled back as a consequence while
he receives treatment.
At
the age of 87, King Harald V of Norway becomes the oldest reigning monarch in
over 1000 years of Norwegian royal history.
The
abdication of Queen Margrethe II of Denmark leads to the accession of her son
and heir, the new King Frederik X of Denmark.
The claimant, recognised by monarchists as King Pavlos
II of Greece, successfully has the Greek citizenship of
himself and his family reinstated, having been stripped of this in 1994.
The claimant, recognised by monarchists as King Leka
II of the Albanians, divorces from Elia Zaharia.
Grand
Duke Henri of Luxembourg delegates some of his powers to his son and heir,
Prince Guillaume, who consequently becomes Regent of Luxembourg. Grand Duke Henri later also announces his
intention to abdicate in 2025.
The
death of the claimant, recognised by monarchists as King Victor Emmanuel IV of Italy, leads to his claim
being inherited by his son, Emanuele Filiberto.
Soon
after arriving in Valencia to visit those affected by floods, King Felipe VI of
Spain and other visiting senior figures are harangued by members of the public
and have mud thrown at them, as a sign of anger with their country’s response
to the floods.
