Grand Duke Henri was born on 16 April 1955 to Grand Duke Jean and Grand Duchess Josephine Charlotte (who was born a Princess of Belgium). His mother was the sister of King Albert II of Belgium, making him first cousins with the reigning King Philippe of Belgium. Henri was educated in Luxembourg and France and undertook military training at Sandhurst in the UK. He married Cuban Maria Teresa Mestre y Batista in 1981. They have five children: Hereditary Grand Duke Guillaume, Prince Felix, Prince Louis, Princess Alexandra and Prince Sebastien. Henri became the Grand Duke of Luxembourg upon the abdication of his father, Jean, in October 2000. The Grand Duke is known to be a gentle soul beloved by his country.

Maria Teresa Mestre y Batista was born in Havana, Cuba, to Jose Mestre and Maria Teresa Batista on 22 March 1956. She and her family left Cuba during the Cuban Revolution after the new dictator and communist Fidel Castro confiscated their properties. Maria Teresa then lived in New York City and later Spain and Switzerland. In Geneva, she met her future husband while they were both studying political science at the Graduate Institute of International and Development Studies. They married on Valentine’s Day in 1981 and have five children. Maria Teresa received heavy criticism following an investigation by the government of Luxembourg and the subsequent Waringo Report that revealed a “culture of fear” in the Grand Ducal Court. The Grand Duchess created the initiative Stand Speak Rise Up! to combat sexual violence.

He attended Sandhurst for military training and is actively involved with the Scouts like his grandfather. The Hereditary Grand Duke married Belgian Countess Stephanie de Lannoy in 2012.
