At age 3, Princess Charlotte is a natural at the whole royal thing, but thanks to a sexist old rule it’s possible her future children won’t get the same chance.
According to British tradition, royal titles are only earned from being born to a prince/reigning monarch or marrying one.
Lucy Hume, associate director of Debrette’s (the authority on British etiquette), told Town & Country, “Royal titles are inherited through sons, so if Princess Charlotte has children they would not automatically inherit the titles ‘HRH,’ ‘Prince’ or ‘Princess.’” So while Prince George and Prince Louis will snag titles for their respective future children (should they have any), Charlotte’s kids won’t…with two exceptions.
The more likely possibility comes into play if (and when) Prince William becomes king. Hume explained, “The monarch may offer to bestow a royal title upon his or her daughter’s children” if all parties so choose.
