Well, their cousins Princess Beatrice and Eugenie come to mind.
Wikipedia is quite good for this. There is a family tree on the British Royal Family page: British royal family - Wikipedia and a general Royal Family page which links to the various current Royal families down the bottom: Royal family - Wikipedia
13? Liechtenstein (Hard to tell, sometimes daughters of Princesses are not given the title Princess automatically)
10 Luxembourg (one or two may be included in other lists, I think one is also a Princess of Liechtenstein)
Several Italian and Yugoslavian.??
5 Norway (with a few daughters not yet made Princesses)
7 in Spain (assuming you’d consider "Infanta= Princess)
7 Swedish
And of course a number of other deposed Royal houses.
Thus at least 80, and a good number are children or under 30.
Quite a few outside Europe, Japan has like 14 “Princesses”. The current King of Saudi has a good number of wives (styled “Princess” by many) and 15 daughters! I’d hazard a guess there are at least 100 “Princesses” in that family.
Can you qualify the OP? Which of the following count:
British royal family only.
European royals only.
Daughters of reigning kings or queens only.
Women of current royal houses only (as opposed to scions of deposed monarchies).
Youths only.
Unmarried women only.
Princesses by birth only (as opposed to by marriage).
For instance, would you consider Princess Michael of Kent, a woman who is married to a cousin of Queen Elizabeth, in your list?
How can she insist she’s still a princess? There hasn’t been a Russian ruling house for the best part of a century. She’s a commoner now, whether she likes it or not. Same deal with all these ex-royals. You can’t claim to be a king, a prince, a princess, a duke, etc when you rule diddly-squat, or at least you can claim it but nobody else should pay any attention to you.
I’m thinking modern day equivalents to fairy tale princesses, so non-deposed monarchies, with a strong bias toward Europe. The ideal would be the immediate family of ruling monarchs, the sort who might have a chance of becoming a queen. If not the direct descendant of a ruling monarch, then one with enough status to be considered a suitable bride to a prince who is in line to the throne.
The closest equivalent in fiction would be Princess Mia from The Princess Diaries.
Looks like Princess Elisabeth of Belgium would be a good match. 8yrs old, she is in line to inherit the throne. Belgium passed a law that does not prohibit first-borns who are female from succession.
Among the titled princesses of functioning monarchies (and I don’t see Monaco listed here; Caroline and Stephanie are the ones I know about), how many are at least commendable role models? I cringe at little girls who emulate Disney princesses for the same reason I cringe at boys who emulate professional wrestlers.
BTW, why exclude royals from deposed monarchies? The rationale is that they have royal genes, not active political power. Prince Phillip, a deposed Greek royal, married the eventual Queen of the UK; why should this board’s rules be stricter than hers in these matters?
There’s Prince Edward’s daughter the Lady Louise Windsor. Legally she’s still entitled to the style Her Royal Highness Princess Louise of Wessex since the Queen hasn’t altered the letters patent that govern titles for royal family members.
