Prince Bernadotte

Prince Bernadotte was a title in the nobility of Luxembourg, conferred upon Oscar Bernadotte by Adolphe of Luxembourg in 1892, and in the nobility of Belgium, conferred upon Carl Bernadotte by Leopold III of Belgium in 1937. It was also used earlier by the founder of their royal House of Bernadotte.

Carl Bernadotte was born Prince of Sweden and Duke of Östergötland, but gave up those titles when he married morganatically in 1937. King Leopold was the widower of Carl's sister Astrid of Sweden and conferred the title on his brother-in-law on the day of Carl's marriage. It had its own arms and was a noble title, that is prince as a high rank of Belgian nobility, not a royal title.

In Sweden, Carl's princely Bernadotte family was considered a part of the unintroduced nobility and joined a private club called Ointroducerad Adels Förening ("The Association of the Unintroduced Nobility"). Prince Carl Bernadotte's title is now extinct, as it was personal to him and his wives. His heirs were designated to be Counts or Countesses Bernadotte. Carl had only one child, Countess Madeleine Bernadotte.

Oscar Bernadotte renounced his titles as Prince of Sweden and Duke of Gotland after he married morganatically in 1888 but was allowed by his father King Oscar II to keep the courtesy title of Prince and then be styled Prince Bernadotte. His and his wife's titles of nobility became official when he was created Prince Bernadotte and Count of Wisborg by his maternal uncle Grand Duke Adolphe of Luxembourg in 1892.
