Henri, Grand Duke of Luxembourg

 Henri von Nassau (born 16 April 1955) is the Grand Duke of Luxembourg, reigning since 7 October 2000. He is the eldest son of Grand Duke Jean and Princess Joséphine-Charlotte of Belgium, and a first cousin of King Philippe of Belgium. In 2019, Henri’s net worth was estimated around US$4 billion

Prince Henri was born on 16 April 1955, at the Betzdorf Castle in Luxembourg as the second child and first son of Hereditary Grand Duke Jean of Luxembourg and his wife, Princess Joséphine-Charlotte of Belgium. His father was the eldest son of Grand Duchess Charlotte of Luxembourg by her husband, Prince Félix of Bourbon-Parma. His mother was the only daughter of King Leopold III of Belgium by his first wife, Princess Astrid of Sweden. The prince's godparents were the Prince of Liège (his maternal uncle) and Princess Marie Gabriele (his paternal aunt).

Henri has four siblings: Archduchess Marie Astrid of Austria (born 1954), Prince Jean of Luxembourg (born 1957), Princess Margaretha of Liechtenstein (born 1957) and Prince Guillaume of Luxembourg (born 1963). On 12 November 1964, when Henri was nine, his grandmother's abdication and his father's subsequent accession as grand duke made him heir apparent. As the grand duke's eldest son, he automatically took the title of hereditary grand duke. 

Henri was educated in Luxembourg and in France, where he obtained his baccalaureate in 1974, after which he undertook military officer training at the Royal Military Academy Sandhurst, England on the Standard Military Course (SMC) 7. He then studied political science at University of Geneva and the Graduate Institute of International Studies, graduating in 1980

While studying in Geneva, Henri met the Cuban-born María Teresa Mestre y Batista, who was also a political science student. They married in Luxembourg in a civil ceremony on 4 February 1981 and a religious ceremony on 14 February 1981 with the previous consent of the grand duke, dated 7 November 1980 and they remain married. The couple has five children: Guillaume, Hereditary Grand Duke of Luxembourg, Prince Félix of Luxembourg, Prince Louis of Luxembourg, Princess Alexandra of Luxembourg, and Prince Sébastien of Luxembourg.
