She saved China!!!!!!!!

Pocahontas and Mulan have too strong of personalities, are too revolutionary.
Cinderella and Belle weren't princesses by birth, so I think that would count against them.
I don't think people would be very accepting of Ariel not being quite human.
So Snow White and Aurora and Jasmine would be the best, and of the three, I feel Snow White would be too quiet and keep to herself, and Jasmine would have too much sass and say and do what she wants, which leaves Aurora with the perfect balance.

I think either Aurora or Cinderella. Their personalities are the most agreeable I think.

I agree with Jillywinkles about Cinderella and Belle.

It is shown in the end that Mulan is beloved by her country at the end. The whole large crowd of people bow out of respect for her saving the country in addition to her receiving a medallion and sword from the emperor.

^ They bowed down and showed respect because they had to since the Emperor did, as that is their culture. It doesn't mean they personally agreed. Jillywinkles was right, Pocahontas and Mulan are too revolutionary as well as Jasmine though. Cinderella and Belle aren't princesses by birth so that would count against them for being so beloved. Snow White and Aurora are the best choices but I chose Aurora because her kingdom rejoiced in her birth and rejoiced when they knew she was coming back after 16 years even though they didn't get to know her. The kingdom seemed to be in love with Aurora at her birth.
