How Did Hermione Get into Hogwarts (If Her Parents Are Muggles)

Every Harry Potter fan knows Hermione Granger, our beloved and highly intelligent muggle-born witch who played an integral part in the success of the trio—Harry Potter, Ron Weasley, and herself—in their efforts to defeat the Dark Lord, Voldemort. Her unprecedented magical prowess and intelligence have often left us spellbound. However, an intriguing question frequently asked by fans is, “How did Hermione Granger, a muggle-born, get into Hogwarts School of Witchcraft and Wizardry?”

Well, the fact is Hermione was accepted into Hogwarts due to her magical abilities, predicted by the magical quill and the book of admittance, and confirmed by her acceptance letter.

In this article we’ll delve into the magical world of Harry Potter to understand the enchanting journey of Hermione Granger, from being the daughter of dentists to becoming one of the most brilliant students Hogwarts ever had.


To begin with, let’s clarify what ‘muggle-born’ means. Muggle-born witches and wizards, such as Hermione Granger, are individuals born to non-magical parents, often referred to as ‘muggles’.

Despite their parents’ non-magical status, these muggle-borns exhibit magical abilities from a young age, much to the wonderment of their families. But how are these abilities identified and acknowledged by the magical world? That’s where the magic of Hogwarts comes into play.

How Did Hermione Get into Hogwarts (If Her Parents Are Muggles)?

Hogwarts School of Witchcraft and Wizardry is the magical institution where young witches and wizards in Britain get their education. Its enchanting admission process begins at the moment of a magical child’s birth. Yes, you read that right! From the moment a magical child is born, their name is inscribed into the Hogwarts register by the magical quill of acceptance, whether they are born into a magical family or a muggle one, like Hermione Granger.

This magical quill works in tandem with the enchanted book of admittance. These two items have the uncanny ability to predict which children will develop magical abilities. Once a child’s name is written by the quill, the book either allows the name to remain or snaps shut, indicating the child is a squib, a person born into a magical family but lacking magical abilities. In Hermione’s case, her name remained in the book, signifying she was indeed a witch.

The Hogwarts Acceptance Letter

Once the magical potential of a child, like Hermione Granger, is recognized by the magical quill and book, the Hogwarts acceptance letter is sent when the child turns eleven. This letter is a formal invitation to join Hogwarts School of Witchcraft and Wizardry, usually delivered by owls, the magical world’s primary means of communication.

In the case of muggle-born students, a Hogwarts representative often visits the family in person. This is to explain the existence of the magical world, the reason behind the unusual phenomena surrounding the child, and to help the family understand the contents of the letter.

In “Harry Potter and the Philosopher’s Stone,” Hermione mentions that she had received her letter and was waiting on the platform for the Hogwarts Express, indicating that a representative of Hogwarts had already visited her and her parents, explained the situation, and provided them with all the necessary information.

Hermione Granger’s Unprecedented Brilliance

Despite being a muggle-born, Hermione Granger was, without doubt, one of the most brilliant witches of her age. Her entry into Hogwarts marked the beginning of her remarkable journey from being an ordinary girl to becoming a magical prodigy.

Hermione’s diligence, thirst for knowledge, and dedication to magical studies made her a unique and remarkable student. Her magic was strong, and her will stronger, proving that one’s lineage doesn’t determine their magical prowess.

Was Hermione Adopted by Her Muggle Parents?

No, Hermione Granger was not adopted. Hermione is the biological daughter of Mr. and Mrs. Granger, who are both Muggles, working as dentists. She is referred to as a “Muggle-born” witch in the Harry Potter series, which means that she was born to non-magical parents but has magical abilities.

This is similar to the concept of a “mutant” or “meta-human” in other popular culture franchises, where an individual exhibits superhuman capabilities despite being born to ordinary parents.

How Do Muggle-Borns Know They’re Wizards?

The process of informing Muggle-born witches and wizards about their magical abilities is handled delicately by the magical world, specifically by the Hogwarts School of Witchcraft and Wizardry.

As we already mentioned, when Muggle-borns, such as Hermione Granger, turn eleven, they receive a letter of acceptance from Hogwarts. The letter reveals their magical heritage and invites them to attend Hogwarts to learn about magic and develop their abilities. However, unlike families already familiar with the magical world, Muggle families often require additional explanation about their child’s magical abilities and the existence of the wizarding world.

Therefore, a Hogwarts staff member, typically a professor, is usually assigned to visit the Muggle-born child and their family. This person is responsible for explaining the wizarding world, answering questions, and helping the family understand the contents of the Hogwarts letter.

This is implied in the first book of the series, “Harry Potter and the Philosopher’s Stone,” when Hermione Granger meets Harry Potter and Ron Weasley, already having extensive knowledge about the magical world. This suggests that a representative of Hogwarts had already visited her and her parents, explained about magic, and answered their questions.

Muggle-born witches and wizards often display signs of their magical abilities from a young age, even if they are unaware of the magical world. These can be small signs like things happening around them without explanation, such as objects moving or strange occurrences that can’t be explained by normal laws of physics. However, without knowledge of the magical world, these events are often dismissed as coincidence or the product of an overactive imagination, until the arrival of the Hogwarts acceptance letter.

Can Muggles Join Slytherin?

Muggles, or non-magical individuals, cannot attend Hogwarts or join any of its houses, including Slytherin, as they do not possess magical abilities. However, Muggle-born witches and wizards—individuals born to non-magical parents but possessing magical abilities—can indeed attend Hogwarts and join any of the four houses.

Slytherin house, founded by Salazar Slytherin, has a complex history regarding Muggle-borns. Salazar Slytherin was known for his preference for pure-blood students, or students who come from entirely magical families, and this preference has been a significant part of the house’s identity. He was wary of admitting Muggle-born students, due to his belief that they might not be trustworthy.

However, after Salazar Slytherin’s departure from the school, the remaining founders—Godric Gryffindor, Helga Hufflepuff, and Rowena Ravenclaw—continued to accept students from all backgrounds, including Muggle-borns, into Hogwarts. The tradition of accepting Muggle-borns into the school continues to this day.

While it is true that Slytherin has had fewer Muggle-born students compared to the other houses due to its historical preference for pure-bloods, there is no definitive rule against Muggle-borns being sorted into Slytherin. The Sorting Hat places students based on their qualities and potential, not their blood status. Therefore, a Muggle-born with characteristics valued by Slytherin—such as cunning, resourcefulness, and ambition—could potentially be sorted into Slytherin.

How Can Two Muggles Have a Wizard Child?

While the series does not go into detailed genetics or mechanics of how magic is passed down, it hints that magical ability is an inherent trait that can surface in families, even after several generations of non-magical individuals. This suggests a possible genetic component to the inheritance of magical ability.

J.K. Rowling, the author of the Harry Potter series, once stated that magic is a dominant and resilient gene. According to her, magic could “hide” for generations within Muggle families before resurfacing. This is how two non-magical parents can produce a magical child.

Additionally, Rowling explained that a Squib (a non-magical person born to at least one magical parent) might have magical relatives many generations back, and the “wizard gene” resurfaces in their offspring. Thus, the child of a Squib and a Muggle could potentially be magical.

Is Ron a Pure Blood?

How Did Hermione Get into Hogwarts (If Her Parents Are Muggles)

Ron Weasley, one of the main characters in the Harry Potter series, is a pure-blood wizard. A pure-blood is a term within the Harry Potter universe used to denote witches or wizards who come from families where all members have magical abilities and none are Muggles or Muggle-borns.

The Weasley family is known for being a pure-blood family, though they are often looked down upon by some other pure-blood families for their lack of wealth and their positive attitude toward Muggles and Muggle-borns.

The Weasleys, including Ron, stand in stark contrast to the stereotypical pure-blood supremacist view seen in some other pure-blood families, such as the Malfoys, demonstrating the values of inclusiveness, equality, and love for all, regardless of blood status.
