Good morning. Today we begin with a small European nation that just crossed a big milestone. One week ago, on 3 October 2026, Grand Duke Guillaume of Luxembourg completed his first full year on the throne. In Luxembourgish, the word for it is Trounwissel – the change of reign – and the court’s own anniversary post says it all in three words: “E Joer Trounwissel.” One year since the change of reign. It has been twelve months of ceremony, regional tours, and steady, deliberate leadership.
The day it happened
The handover took place exactly a year ago, on 3 October 2025. Grand Duke Henri, Guillaume’s father, closed a 25-year reign by signing the abdication in the Salle des Fetes at the Grand Ducal Palace. Prime Minister Luc Frieden read the grand ducal decree aloud, and Guillaume took the oath: “I swear to observe the Constitution and the laws and to faithfully fulfill my constitutional duties.” Then came a balcony appearance, a walk to City Hall past the crowds gathered on Place Guillaume II, and a gala dinner that evening. As successions go, it was about as smooth as European royalty has staged in years.
Guillaume was ready. He is the eldest son of Grand Duke Henri and Grand Duchess Maria Teresa, has been heir apparent since 2000, and served as Regent from October 2024 – a full year of hands-on preparation before the crown officially passed to him.
A reign with a theme
In his first Christmas address in December 2025, the new Grand Duke laid out the values he wants his reign to stand for: cohesion, solidarity, openness, and tolerance. He also announced the Joyeuses Entrees tour – five regional visits across 2026 and 2027, a tradition that takes the Grand Duke out into the country’s regions rather than waiting for them to come to him.
Three stops are already done. The tour opened in Esch-sur-Alzette on 24 April 2026, moved north to Troisvierges on 10 July 2026, and reached Ehnen and Wormeldange on the Moselle on 2 October 2026 – the very eve of the anniversary, a piece of scheduling that feels entirely deliberate. Esch-sur-Alzette has already featured prominently in this reign, and two more stops are set for 2027: Beckerich and Mersch.
The year’s grandest evening
Late September brought one of the most glittering moments of the first year: a white-tie state banquet at the Grand Ducal Palace for Finnish President Alexander Stubb and Suzanne Innes-Stubb. Both guests received the Order of the White Rose of Finland, one of the country’s highest honors. It was a reminder that Luxembourg’s monarchy, for all its modest size, still knows how to do statecraft in the grand manner.
The anniversary is even being minted into history. A 2026 Luxembourg 2-euro commemorative coin honors both the accession and the Grand Duke’s 45th birthday – the kind of small, everyday object that will keep passing through people’s hands long after the speeches are over.
The Grand Duchess’s parallel year
Grand Duchess Stephanie has had a full first year of her own alongside her husband. Her engagements included a visit to the Pro Familia foundation in Esch-sur-Alzette, and an anti-poverty visit to ATD Quart Monde in Beggen – which the Grand Duke joined himself. The couple’s commitment to the fight against poverty has been one of the clearest throughlines of their work this year.
And in her role as president of the Luxembourg Red Cross, Stephanie presented 160 blood-donor medals in Diekirch today, 10 October 2026 – a fitting piece of public service to land on the anniversary week.
What’s next
With the first year complete, the calendar is already filling up. The Joyeuses Entrees tour continues to Beckerich and Mersch in 2027, and the tone Guillaume has set – cohesion, solidarity, openness, tolerance – will be tested against the everyday business of a modern constitutional monarchy. On the evidence of year one, he intends to meet people where they are. That, more than any single ceremony, may end up being the defining gesture of the Trounwissel.
