The Grand Ducal Court of Luxembourg has released six photos to mark Grand Duke Jean’s 97th Birthday, including one featuring three generations.

Prince Jean was educated in Luxembourg and completed secondary school at the Catholic boarding school Ampleforth College in the UK.

He became the Hereditary Grand Duke, as their heir-apparent, when he came of age on 5 January 1939.

However, on 6 October 1942, Prince Félix and the Hereditary Grand Duke arrived in Great Britain to join the British Army, Prince Jean joined the Irish Guards, following King George VI’s advice, and studied at the Military Academy at Sandhurst, where he obtained the rank of Second Lieutenant on 28 July 1943. He also addressed the people of Luxembourg via BBC radio on the same day.

In August 1943, Prince Jean served as a guard at Buckingham Palace and remembered his mother and sisters’ visit whilst on duty, as he had to remain motionless the whole time!

He landed in Normandy on 11 June 1944, as remember of a reinforcement unit, and took part in the Battle of Caen (Operation Goodwood) and the liberation of Brussels. He also served on the military staff of the 32nd brigade of the Guards Armoured Division in Normandy.

On 10 September 1944, he crossed the border at Rodange with his father, Prince Félix, and participated in the liberation of Luxembourg from Nazi occupation.

However, Prince Jean fought in the Battle of the Bulge to block the German route towards Antwerp.

Once the German resistance had been broken, Prince Jean, as part of the Guards Armoured Division began moving towards Bremen and Hamburg.

At the beginning of April 1945, Prince Jean received orders to return to Luxembourg to welcome his mother, Grand Duchess Charlotte who arrived home to an overjoyed population.

Grand Duke Jean was appointed as a Stranger Knight of Britain’s most prestigious order of chivalry, the Order of the Garter in 1972.

Queen Elizabeth II of Great Britain promoted Prince Jean to Colonel of the Irish Guards regiment on 21 August 1984 and made Honorary General of the British Army on 17 March 1995.


Prince Jean married Princess Josephine-Charlotte of Belgium at Luxembourg Cathedral. They set up home at the Château de Betzdorf where their five children, Princess Marie-Astrid, Prince Henri, Prince Jean, Princess Margaretha and Prince Guillaume were born.

His eldest daughter Marie-Astrid was once considered as an eligible bride for Prince Charles during the 1970s but a match was unlikely under the terms of the Act of Settlement 1701, which prevented the heir to the British monarchy marrying a Catholic.


Grand Duchess Charlotte signed her act of abdication on 12 November 1964, so Jean, the Hereditary Grand Duke, became the 8th Luxembourg sovereign since the Grand Duchy was founded in 1815.

His reign was one of the most prosperous ever known by the Grand Duchy which contributed to political, economic and social life in Luxembourg, and providing an unprecedented stability for the nation.

He ended his reign on 7 October 2000, stepping down in favour of his eldest son, Grand Duke Henri.
