The pure - blood families would be the most resistant. They would see Queen Elizabeth as an outsider and someone who doesn't understand the 'pure' wizarding ways. The Malfoys, for example, would try to undermine her at every turn. But the more progressive wizarding families, like the Weasleys, would welcome her. They would see her as a chance to break down the barriers between Muggles and wizards. And the students at Hogwarts would be divided at first, but as they see the positive changes she brings, more and more of them would support her.
The knights in Westeros would be both intrigued and a bit intimidated. Harry's magic is something they've never seen before. Some might want to learn from him, while others might see him as a threat to their traditional way of fighting. The maesters would be very interested in studying his magic, trying to figure out how it works and how it could be incorporated into their knowledge. The children in Westeros would probably be in awe of him, especially if he shows off some cool magic tricks. They might start dreaming of becoming wizards themselves, which would be a huge change in their aspirations.
One possible plot could be that Queen Elizabeth discovers she has magical powers and is secretly a part of the wizarding world. She decides to use her influence in the Muggle world and her new - found magical abilities to bring about a new era of cooperation between the two worlds. She could visit Hogwarts and offer her wisdom and resources to help improve the school, while also learning more about magic herself.
The international relations of the wizarding world would be redrawn. Queen Elizabeth would use her diplomatic skills to strengthen ties with other wizarding countries. She might also introduce new trade policies. For example, trading magical artifacts for Muggle - made goods that could be useful in the wizarding world. The story could also explore how the wizarding world, under her rule, would interact with the Muggle world on a more regular basis. This could lead to some interesting plotlines, like how Muggles would react to the existence of a wizard - ruling queen and how the wizarding world would keep their secrets while still having a closer relationship with Muggles.
A possible scenario is that Queen Elizabeth has a magical artifact that has been passed down through generations in the royal family. This artifact draws the attention of Harry Potter and his friends. They come to her palace to investigate, and she becomes involved in their adventures. She could offer them resources and protection in the Muggle world, while they introduce her to the wonders of the wizarding world.
Harry would likely be very curious about the court and its people. He might use his magic in small, discreet ways to amuse the courtiers, like making a flower bloom in his hand. He would probably be polite and respectful, but also a bit of an outsider. His different style of dress and his magic would make him stand out, and he'd have to explain himself carefully to avoid being seen as a threat.
She could completely transform the Ministry of Magic. Given her experience in governing, she might restructure it to be more efficient. For example, she could create new departments to deal with things like the proper handling of magical creatures in a more humane way. And in terms of the education system, she might introduce a more comprehensive curriculum that includes not only magic but also Muggle studies from a historical and cultural perspective.
Well, characters would interact based on Disney's family - friendly values. There would be no real animosity between characters as they would all be part of the Disney - dominated world. Old rivalries might be forgotten. The animal characters could communicate with humans more easily, like Simba from The Lion King could be a spokesperson for the animal kingdom and negotiate with human leaders about environmental protection and co - existence. There would also be a lot of singing and dancing interactions as is typical in Disney stories.
In a fan fiction, the Ministry of Magic might approach Queen Elizabeth when they need a liaison between the magical and Muggle worlds. She, being the Queen of the Muggle Britain, could be a great asset. Their interactions would involve discussions about how to keep the balance, like when a magical event might accidentally spill over into the Muggle world. The Ministry would explain the magical side of things, and she would provide the Muggle perspective and how to handle the situation from that end.
It might entail Queen Elizabeth as a character in the wizarding world. She could be a guest at Hogwarts, and all the students are curious about her. She might give a speech about leadership and how it's similar in the Muggle and wizarding worlds.
Hermione, on the other hand, would likely have a more critical view. She'd analyze the fanfictions for their accuracy in terms of magic lore and Hogwarts traditions. If there were any inaccuracies, she'd be quite perturbed. However, she might also appreciate the creativity that goes into some of the well - written ones that add new dimensions to their magical world.
