Crown Prince Rupprecht(or Rupert) of Bavaria was the last Bavarian Crown Prince.
His full title was His Royal Highness Rupprecht Maria Luitpold Ferdinand, Crown Prince of Bavaria, Duke of Bavaria, of Franconia and in Swabia, Count Palatine of the Rhine.
Rupprecht was born in Munich, the eldest son of Ludwig III, the last King of Bavaria, and of Archduchess Maria Theresia of Austria-Este, niece of Duke Francis V of Modena. He commanded the German Sixth Army at the outbreak of World War I in Lorraine. Rupprecht succeeded in holding back the French attack in August 1914, in the Battle of Lorraine, and then launched a counteroffensive later that month. Rupprecht failed to break through the French lines and remained on the Western Front during the stalemate that would last until the end of the war. Rupprecht achieved the rank of field marshal (Generalfeldmarschall) in 1916 and assumed command of Army Group Rupprecht. Rupprecht has been considered by some to be one of the best Royal commanders in the Imperial German Army of World War I.
Rupprecht married firstly, in 1900, Duchess Marie Gabriele in Bavaria, and secondly, on 7 April 1921, Princess Antoinette of Luxembourg, the sister of Grand Duchess Charlotte of Luxembourg.
Rupprecht lost his chance to rule Bavaria when it became a republic in the revolutions that followed the war. Some royalists still referred to him as the King of Bavaria. Rupprecht was opposed to the regime of Nazi Germany and was forced into exile in Italy in 1939.
In October 1944, when Germany occupied Hungary, Rupprecht evaded arrest but his wife and children were captured. They were first imprisoned in the Sachsenhausen concentration camp at Oranienburg, Brandenburg. In April 1945 they were moved to the Dachau concentration camp, where they were liberated by the United States Army. Crown Princess Antoinette never recovered completely from the captivity, and died a few years later.
Rupert died at Schloss Leutstetten, August 2, 1955, when he was succeeded in his British rights by his elder son, Albert. For his funeral, the royal crown and scepter of Bavaria were withdrawn from the Bavarian State Museum and placed on his coffin. His remains lie in the crypt of the Theatinerkirche in Munich.
