The Grand Duchy of Luxembourg is a constitutional monarchy. The Grand Duke is its representative as head of state. In the event of death or abdication, monarchical continuity is ensured by his successor, as it appears in the order of succession preestablished by the Nassau family pact. Currently, Grand Duke Henri’s direct heir is his eldest son, 42-year-old Hereditary Grand Duke Guillaume.

Grand Duke Henri will cede prerogatives to his eldest son

As in many monarchies, a system of regency can also be put in place in the event of the sovereign’s incapacity. In the Grand Duchy, there is also a system of lieutenancy provided by a lieutenant representative. This lieutenancy takes place if the sovereign decides to entrust certain prerogatives to his successor. At the age of 69, Grand Duke Henri made the decision to establish a lieutenancy this fall.

Hereditary Grand Duke William will then have to take an oath to observe the Constitution before exercising his powers. “I swear to observe the Constitution and the laws and to faithfully fulfill my constitutional duties », he will have to pronounce, as indicated in article 58 of the new Constitution which came into force in July 2023.

A mandate will also delimit the prerogatives of the lieutenant representative. Grand Duke Henri, himself his father’s crown prince, was appointed lieutenant in 1998. His lieutenantship ended in 2000, when he finally acceded to the throne, following his father’s abdication. There have already been five lieutenancies in the Grand Duchy of Luxembourg, a country where abdication has also become a custom. Grand Duke Henri’s father, grandmother and great-aunt all abdicated in their time.

Hereditary Grand Duke William is already well prepared for the role. He has ensured numerous commitments with his wife, Hereditary Grand Duchess Stéphanie, for many years. Hereditary Grand Duke William himself became the father of his own heir in March, with the birth of his first son, Prince Charles. Last year, the heir couple welcomed a second boy, Prince Francis.
