Guillaume Takes Oath as Luxembourg’s New Grand Duke

Luxembourg Welcomes New Grand Duke Guillaume Amidst Celebrations

The Royal Transition in Luxembourg

The historic throne room of the Luxembourg Chamber of Deputies was abuzz with excitement as Guillaume, the newly appointed Grand Duke, pledged, “I swear to observe the Constitution and the laws.” Surrounded by European royals and leaders, Guillaume’s declaration marked the beginning of a new chapter for the Grand Duchy.

A New Era for Luxembourg’s Monarchy

Following the emotional abdication of his father, the 70-year-old Henri, Guillaume is set to lead Luxembourg into a new era. The new grand-ducal couple, Guillaume and his wife Stéphanie, are expected to engage with locals in the historic district of Luxembourg City. Among the 670,000 inhabitants of Luxembourg, nearly half are foreigners, illustrating the country’s diverse demographics.

Luxembourg Celebrates ‘Trounwiessel’

In honor of the transition, Luxembourg is hosting a series of festivities until Sunday to celebrate “Trounwiessel” (“Change of the throne” in Luxembourgish). The events will culminate in a gala dinner featuring key figures like French President Emmanuel Macron and German President Frank-Walter Steinmeier.

Guillaume’s Global Perspective

• Seventh sovereign of the Nassau-Weilbourg dynasty, reigning since 1890.
• Educated both locally and abroad, symbolizing Luxembourg’s blend of tradition and modernity.
• Anticipated to bring a more open style while maintaining traditional stability.

Prime Minister Luc Frieden remarked on this historic occasion, “The grand duke embodies the independence and stability of the state,” anticipating a balance of continuity and subtle modernization.

Family and Heritage

Guillaume, the eldest of five children born to Henri and Maria Teresa Mestre of Cuban descent, continues a legacy deeply entwined with Luxembourg’s identity. His wife, Stéphanie de Lannoy, hails from Belgian nobility and shares a passion for art and literature along with fluency in multiple languages.

Transition of Leadership

Former Grand Duke Henri initiated the transition process in 2024, expressing a wish to “slow down” after 25 years on the throne. Guillaume’s global education, including stints in Switzerland, Sandhurst, and France, prepares him to meet the challenges of modern rule while keeping the duchy’s heritage alive.

Anticipation and Optimism for the Future

An excited local, Nicolas Graas, commented on the international attention Luxembourg is garnering, encouraging everyone to watch and celebrate the nation’s momentous event. As the country honors its heritage and looks forward, this transition reflects the balance of tradition and evolution under Guillaume’s leadership.
