History Awesome / ThePrincessDiaries

* Mia, Helen and Clarissa being able to calmly discuss the situation after Mia's identity gets leaked shows a lot of CharacterDevelopment since their last discussion, shortly after Mia was told she was a princess. Mia herself decides to stick with princess lessons and see it through before she makes her final decision.

* Mia stabbing Lana in the chest with an ice cream cone after Lana insults Tina.

* Mia stabs Lana in the chest with an ice cream cone and ruins her outfit due to Lana being a bitch to her (as usual). Lana tries to whine and play the victim to Ms. Gupta, only for Ms. Gupta to sarcastically say that she was in a meeting and she can "send her uniform to dry cleaning."

* Philippe doing what he didn't do the first time around and abdicating as prime minister for a second chance with Helen in ''A Royal Wedding.''

* From the second movie, after Viscount Mabrey has staged a humiliating accident while Mia was inspecting the royal guard and Joe has figured out he was behind it:
-->'''Joe:''' Viscount, you may not be aware of what my job entails as the Royal Head of Security. My job is to protect the crown. To make sure no harm comes to the crown. To step in when someone toys with the crown's emotions, you see.
-->'''Viscount Mabrey:''' [[DoubleEntendre I think the entire country understands how well you cater to the crown's emotions]].
-->'''Joe:''' (''[[{{Beat}} pause]], [[BewareTheQuietOnes during which he goes]] [[TranquilFury utterly cold and furious]]'') If you hurt my girl, you will answer directly to me, and whatever crimes I commit against you, remember; I have diplomatic immunity in 46 countries. [[ArsonMurderAndJaywalking Including Puerto Rico]].
-->'''Viscount Mabrey:''' Sir, you will find that the word "fear" is not in my vocabulary!
-->'''Joe:''' Perhaps... but it's in your eyes.
* In the second film, Mia makes a number of major changes to Genovia, including turning her second home, which was used as a resort by parliament members, into a children's home, getting the Genovian parliament to strike down the rule requiring crown princesses to marry before ascending to throne, and ensuring a more egalitarian parliament after she is crowned, as a split scene at the end shows Charlotte and a number of other women donning parliament wigs.

* Philippe doing what he didn't do the first time around and abdicating the throne for a second chance with Helen in ''A Royal Wedding.''

* '''Meta:''' In ''Royal Engagement,'' Clarisse sings at Mia's slumber party. This was the first time Creator/JulieAndrews sang onscreen or in public since having throat surgery in 1997 that permanently damaged her voice. She nailed the song on the ''first take'' and moved the crew to tears.

* Phillipe helping Helen and Mr. Gianini [[spoiler: elope to Mexico and avoid]] the tawdry, expensive ShotgunWedding that his mother Clarisse has arranged.

** Lana even later acknowledges it was an awesome speech, and in book 9 recommends Mia to speak to the Domina Rei. Mia kicks it out of the park with her speech about Princess Amelie, a sixteen-year old princess who ruled during the Black Plague, saved lives despite her uncle attempting to usurp the throne and burn her proclamations, and [[spoiler: mandated that Genovia become a constitutional monarchy in her last proclamation.]]
* An OffScreenMomentOfAwesome, but Michael telling Lilly [[spoiler: to be nice to Mia after Lilly created the hate website.]] This probably spurred Lilly's attitude as TheAtoner in book 10.
* Mia becoming a [[spoiler:published novelist at the age of eighteen.]]

* In the second-to-last book, Lana being mature enough to [[spoiler:bury the hatchet with Mia (and, for that matter, Mia agreeing despite what Lana has put her through). She's still sometimes a shallow Main/AlphaBitch but she realises that their feud was childish and they gain a pretty good friendship instead of continuing to fight.]]
