Grand Duke Guillaume Sworn In as Luxembourg’s Youngest Sovereign with European Leaders Present

Grand Duke Guillaume officially ascended the throne of Luxembourg following the abdication of his father, Grand Duke Henri, who reigned for 25 years. The ceremony took place with traditional splendor and was attended by European royals, heads of state, and notable guests including French President Emmanuel Macron and German President Frank-Walter Steinmeier. Guillaume, 43, pledged allegiance to the constitution and laws in a parliamentary oath, marking him as the seventh sovereign of the Nassau-Weilbourg dynasty since 1890. The transition symbolizes continuity and stability in Luxembourg, a parliamentary democracy where the monarch's role is largely representative. Festivities celebrating the new reign included public events, a gala dinner, and a balcony appearance by the Grand Ducal family accompanied by several royal guests. Luxembourg's capital, known for its cosmopolitan population and European heritage, welcomed the new Grand Duke with enthusiasm and optimism for a new generation of leadership.
