Some characters in Disney movies are labelled as Princesses. Is there an official list of these Princesses? Rules to qualify, requirements that must be met?
Disney Princess is a group created by Andy Mooney to market Disney products to girls.
Soon after joining Disney, Mooney attended his first "Disney On Ice" show. While waiting in line, he found himself surrounded by young girls dressed as princesses. "They weren't even Disney products. They were generic princess products," he mused. Soon after realizing the demand, the Disney Princess line was formed. - Disney Wiki
How they were chosen:
The franchise currently comprises eleven female protagonists from ten different Walt Disney Animation Studios films and one Pixar film who are either royal by birth, royal by marriage, or considered a "princess" due to their significant portrayal of heroism in their film.
The characters were not chosen specifically for their royal titles, but rather for how well they fit into what Disney executives deemed "the Princess mythology". Mulan is an example of this concept; she has no familial ties to royalty, but is still included in the character list. Tinker Bell was once included under the same principle before it was decided that she was not suited for the "mythology". - Disney Wiki
Significant portrayal of heroism is good enough to earn the title of princess.
Who is included:
The original Disney Princess line-up featured Snow White, Cinderella, Aurora, Ariel, Belle, Jasmine, Pocahontas and Mulan. It later expanded to include Tiana, Rapunzel and Merida after the successes of their respective films. Princess Moana, the star of Disney's upcoming feature Moana, of 2016, is expected to join the line-up. - Disney Wiki
Apparently Princess Anna and Queen Elsa (Frozen) aren't good enough for this list.
Princess Claim to Royalty:
- Snow White - birth
- Cinderella - marriage
- Aurora - birth
- Ariel - birth
- Belle - marriage
- Jasmine - birth
- Pocahontas - birth+
- Mulan - significant portrayal of heroism
- Tiana - marriage
- Rapunzel - birth
- Merida - birth
Jack covers nicely that Yes, of course there is an official list. This is Disney after all, one of the most successful companies in recent history if not all time.
I would like to add that there is more to the "How" the Princess are selected...
First you need to meet all three of these criteria:
- Primary Role in an animated Disney movie.
- Not primarily star in sequel (i.e. not introduced)
Next you need to meet one of the following criteria:
- Born Royal
- Marry Royal
- Perform an act of heroism (aka the Mulan Rule)
Now of course there are many who meet these requirements but did not make the cut to be a "Disney Princess". That is be because the final, unwritten criteria is box office success.
