Disney Princess is one of the trademarks of Walter Disney Company, which was planned by Andy Mooney, a commodity consultant. In order to gather the heroines in various works under Disney's name, trademarks are widely used in various media and commodities.
This trademark does not refer to all the princesses that actually appeared in the Disney series at that time, but refers to eleven princesses used in the current official copyright, including princesses and princesses (both of which are called princesses in English). Hua Mulan is the only person in this lineup who is not a princess or princess. Non-Disney princesses generally refer to non-Disney-produced princesses and non-Disney official princesses, which are based on a series of non-Disney-produced but Disney-style movies.
Most Disney official princesses have sequels on TV or in movies. Secondly, they also made a guest appearance in the Disney cartoon TV series "Little Princess Sophia". So far, there is no guest princess: Princess pocahontas.
