OP forgot to capitalize the P.

To be included in the Disney Princess line, a character must be a protagonist or main supporting character in an animated theatrical film produced by a studio owned by The Walt Disney Company that is the first film in its franchise (thus excluding characters introduced in sequels, direct-to-video films and television series), must be human in her standard form and in general should be a princess by way of either marriage to a prince or through herself descending from a monarch or tribal chief. Exceptionally heroic characters who do not have a royal title can also be included.

The list of official princesses kept changing over time, mainly because new characters were added to the list as new movies emerged. Still, three princesses were removed from it in 2005: Tinker Bell, Esmeralda, and Jane Porter. The reasons why they made the list in the first place are not entirely clear since they are neither main characters in their films nor do they have royal heritage.

[…] In Esmeralda’s case, the reason was that the sales of The Hunchback of Notre Dame products were not going as Disney had hoped, and the character was not as popular with the audience.

But as the reply said, Alice is not a Disney Princess nor a princess.
