Luxembourg experienced a historic and peaceful transition of power on October 3, 2025, as Grand Duke Henri formally abdicated his throne after a 25-year reign. His eldest son, Hereditary Grand Duke Guillaume, has now ascended to become the new Grand Duke, ushering in a new era for the Grand Duchy.
The abdication ceremony was held at the Grand Ducal Palace at 10:00 AM local time. This was followed by Guillaume's official swearing-in ceremony at the Chamber of Deputies. Grand Duke Henri, who is 70 years old, had announced his intention to step down on June 23, 2024, during his address, setting the stage for this meticulously planned succession.
Hereditary Grand Duke Guillaume, now 43, has been actively preparing for his new role. He received his education in the United Kingdom, France, and Switzerland, and underwent training at the Royal Military Academy Sandhurst. His wife, Grand Duchess Stéphanie, is also ready to support him in this new role. He was appointed Lieutenant Representative in October 8, 2024, a traditional precursor to accession. This transition highlights Luxembourg's enduring commitment to continuity and stability within its constitutional monarchy.
Grand Duke Henri expressed his confidence in the incoming generation to guide Luxembourg towards a more peaceful and sustainable future. The significant event was attended by a distinguished assembly of dignitaries, including members of the Dutch and Belgian Royal Families, French President Emmanuel Macron with his wife Brigitte Macron, and German President Frank-Walter Steinmeier with his wife Elke Büdenbender, underscoring Luxembourg's prominent standing on the European stage.
Guillaume's ascension also positions his five-year-old son, Charles, born in 2020, as second in line to the throne, and Prince François, born in 2023, as third in line. This moment signifies more than just a change in leadership; it represents a continuation of tradition coupled with a forward-looking perspective for Luxembourg.
