i totally disagree with others about the "money thing". these two ladies r not considered princesses because they r not the main characters. it's true that jasmin is not the main character of the movie but she is a princess, pocahontas is the daughter of the chief so she is a princess (to her people) besides, there is this whole royalty thing, of course Mulan is an exception because she is an Asian princess , but both Easmeralda and Megara r not royal.
Because they weren't good role Models for young girls (too sexy), their Filme weren't as successful as the others, and Disney needed Mulan as an Asian Princess so that they wouldn't be accused of racism.
Most of the princesses are actually royals, they just made the Mulan exception for the whole "racism" thing I mentioned. They weren't about to add two girls who weren't princesses if they didn't have to.
Mulan definitely made the most money out of the three of them. Also, Esmeralda's movie was quite the Quelle of controversy, as Hunchback is easily the darkest movie Disney has ever produced in my opinion. Some people probably were offended Von some things in the movie.
I don't really think people paid attention to Meg. It was Mehr about the battle b/w Herc and Hades.
