High Quality Content by WIKIPEDIA articles! Crown Prince Rupprecht of Bavaria or Crown Prince Rupert of Bavaria (18 May 1869 2 August 1955) 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. He was also the Jacobite heir to the thrones of England, Ireland, Scotland and France from the death of his mother in 1919. Rupprecht's grandfather, Luitpold, became de-facto ruler of Bavaria when King Ludwig II and his successor Otto both were declared insane in 1886. Rupprecht's own position changed somewhat through these events as it became clear that he was likely to succeed to the Bavarian throne one day.
