Prince Philip Ordered Charles to Marry Diana – True, Sort of
The Crown provides a distinct answer to why Charles proposed to Diana if he was so in love with Camilla and cared so little for Diana. The show suggests that after Diana’s first visit to Balmoral, Charles’ father summoned him to the hanging room where they skinned and hunted wildlife. Although it is quite a forceful metaphor, Prince Philip virtually commands Charles to propose in the scene.
This meet-up most likely never happened. Instead, Philip contacted Charles and told him to either marry Diana or end the relationship because she was being harassed a lot by the media even back then. Charles supposedly misinterpreted that as an ultimatum and proposed marriage.
