One of the most notable instances of antisemitism within the British royal family was the abdication crisis of 1936. King Edward VIII, who was in love with an American divorcee named Wallis Simpson, was forced to abdicate the throne after the government refused to allow him to marry her. Many people believe that the government's opposition to the marriage was due in part to Simpson's Jewish heritage.
Another well-known instance of antisemitism within the royal family was the case of Princess Alice, Duchess of Gloucester. Princess Alice was a vocal supporter of the Nazi Party, and she even met with Hitler on several occasions. In 1947, she was stripped of her royal titles after she was found to have been spying for the Nazis.
In recent years, there have been several instances of members of the royal family speaking out against antisemitism. In 2019, Prince Harry and Meghan Markle condemned antisemitism in a statement released to the press. In 2020, Prince Charles and Camilla, Duchess of Cornwall, visited a Holocaust memorial in London and met with survivors of the Holocaust.
The British Royal Family has a complex history with antisemitism. There have been many instances of individual members of the royal family making antisemitic remarks or expressing antisemitic views. However, the royal family as an institution has never officially declared itself to be antisemitic, and some members of the royal family have spoken out against antisemitism.
