When did Princess Aurora join the Disney Princess characters at Disneyland?

When I went to Disneyland in 1998 for Christmas I was very lucky to meet Princess Aurora for the very first time and get her autograph and Mom had never ever seen Princess Aurora before in Disneyland and so i'm curious to know when Disneyland debuted the Princess Aurora character? Did she debut in honor of the rerelease of Sleeping Beauty in 1997? Because I don't recall seeing her when I first went in 1991. Also did she debut in her pink dress or her blue dress? Because the first time I met Princess Aurora she wore her blue dress and so I wonder if that's the more easier to find version of Princess Aurora? Also was Prince Phillip and the Three Good Fairies debut along with Aurora or were they added later? I love learning facts about Disneyland characters and their history and I think it's an awesome way to learn trivia and facts
