"I really don't think they should let the other sort in, do you? They're just not the same, they've never been brought up to know our ways. Some of them have never even heard of Hogwarts until they get the letter, imagine. I think they should keep it in the old wizarding families."
— Draco Malfoy's pure-blood prejudice at an early age[src]
DH1 The Malfoy Family

The Malfoys and the Lestranges were bastions of the philosophy of pure-blood supremacism

Pure-blood supremacy,[1] or the pure-blood doctrine,[2][3] was the belief that wizards and witches whose family had not married any Muggles or Muggle-borns were superior to wizards and witches who had done so. Proponents of this ideology typically regarded Muggle-born wizards as 'impure' and unworthy of possessing magical ability; pure-blood supremacists often actively discriminated against Muggle-borns for these reasons.[2]


Lucius Malfoy: "Dear me, what’s the use of being a disgrace to the name of wizard if they don’t even pay you well for it?"
Arthur Weasley: "We have a very different idea of what disgraces the name of wizard, Malfoy."
Lucius Malfoy: "Clearly, the company you keep, Weasley… and I thought your family could sink no lower."

A piece of propaganda directed towards Muggle-borns

During the tenth century and presumably into the Renaissance, pure-blood supremacism was considered a misguided opinion. However, after the International Statute of Wizarding Secrecy was put into effect in 1692, wizards started to go into hiding fearing persecution from Muggles. This led to a shift in magical opinion and a growth in pure-blood supremacist thought. Some followers of the pure-blood doctrine advocated all-out war against the Muggles, though clearer heads prevailed. At this time, the so-called 'pure-bloods' were not necessarily pure, but it was more of a statement of political and social intent (i.e., "I will not marry a Muggle and I consider Muggle/wizard marriage reprehensible").[2]

Indeed, later pure-blood supremacists in the 21st century believed that only pure-bloods were 'real' witches and wizards. Many of them were inclined considered pure-bloods to be the elite people of the wizarding world, and some did not consider half-bloods and Muggle-borns to have that same dignity. Pure-blood supremacists were prone to be very hostile towards both Muggle-borns, as well as those that were accepting of them, fearing that the promotion and acceptance of the mixture of magical and non-magical blood would dilute or even negate the wizard identity. They also considered themselves to be "above" half-bloods because they had not married any Muggles and were not related to them.

More militant subscribers of this philosophy even considered themselves to be akin to royalty. They viewed Muggles, Muggle-borns, half-bloods, and half-breeds with contempt, and considered the Muggle world to be inferior to their own. Pure-bloods (and even half-bloods) who did not share this view were considered traitors to their own kind or "blood traitors". They were considered disgraces by pure-blood supremacists such as the Malfoys and the Blacks.[2]

Elitist pure-bloods even believed that it was a sign of weak magic to enjoy the company of non-magical friends[4] and seemed to believe that some of the supposed dirtiness of Muggles and Muggle-borns would rub off on those who associated with them, thus they considered the so-called blood traitors to be "filthy" as well.[5] Some extremists considered blood traitors to be nearly as bad as the Muggle-borns they were prejudiced against. Bellatrix Lestrange, for example, claimed that "blood traitor is next to Mudblood in [her] book", and her family often disowned and blasted off the family tree any members who could be considered blood traitors. Blood traitors might also be shunned by their families and acquaintances: for example, Bellatrix and her younger sister Narcissa Malfoy stopped seeing their sister Andromeda after she married a Muggle-born wizard, Ted Tonks.[6]

Lord Voldemort and his Death Eaters targeted blood traitors during the First and Second Wizarding Wars because they opposed their goals. While they were temporarily in control of the Ministry of Magic in late 1997 and early 1998, they kept blood traitors such as Arthur Weasley under surveillance.

However, even most Death Eaters were reluctant to kill pure-bloods, even "traitorous" ones, if it could be avoided. Similarly, although disdaining half-bloods and considering them inferior, they recognised that there were not enough pure-blood families left and so (if only begrudgingly), accepted half-bloods in their new world order. The same situation existed at Hogwarts School of Witchcraft and Wizardry while Voldemort was in power.[7]

Degrees of prejudice[]

Pure-blood elitism[]

"Toujours Pur"
— "Always Pure", the motto of the House of Black[src]

The most extreme of the pure-blood supremacists sought to purge the world of those they consider "impure". They often tolerated half-bloods out of necessity (though still disdained them), but Muggle-borns were persecuted and Muggles were viewed as nothing more than animals. Supremacists debated amongst themselves whether Muggles and Muggle-borns should be subject to death or slavery, but they generally agreed goal of pure-blood supremacy was a world where Muggles are relegated to at least a lesser role.

“Pure-blood elitists” Reason(s)
House of Black The Blacks' family motto meant "always pure" in French. As such, they guarded their strict adherence to blood purity zealously, going as far as inbreeding occasionally to retain great good looks and pure-blood status. Many members of the House of Black were disowned for marrying Muggles or Muggle-borns, or for refusing to uphold the family's prejudiced views. Even being a Squib is considered to be impure as well and would be disowned.[2]
Phineas Nigellus Black was Headmaster of Hogwarts from some point in the late 19th century to 1925. He disowned his second eldest son Phineas for supporting Muggle rights.[8]
Cygnus Black II disowned his youngest son Marius for being a Squib.
Pollux Black disowned his eldest son Alphard for supporting his disowned nephew.[8]
Orion and Walburga Black were originally distant supporters of the Death Eater cause. They disowned their eldest son Sirius for running away to the Blood traitor Potter family whilst supporting their youngest Regulus for joining the Death Eaters, but eventually felt the Death Eaters were going too far and withdrew their support.[8]
Cygnus Black III disowned his middle daughter Andromeda for marrying Muggle-born Edward Tonks.
Araminta Meliflua Black was an activist for Muggle-hunting, she attempted to force passage of a bill at the Ministry that would have legalised it as a sport.[8]
House of Gaunt The Gaunts represented the worst aspects of pure-blood supremacy. Having been descended from important families such as the Slytherins and Peverells, they were known to have inbred most heavily than any pure-blood elitist, in order to retain the ability to speak Parseltongue. This tendency forced them to squander the family gold up until the early 20th century.[9]
Ominis Gaunt's mother, father and older siblings, all being well-versed in performing the Cruciatus Curse, regularly performed the curse on Muggles "for sport".
Gormlaith Gaunt resided on Coomcallee from 1603 to 1634, jinxing any Muggles who wandered near her home. Since murdering her sister Rionach and brother-in-law William Sayre for fraternising with their Muggle neighbours, she raised their daughter Isolt in seclusion, and forbade her of attending Hogwarts due to its pro-Muggle leanings. However, Isolt fled to the New World aboard the Mayflower in 1620, and went on to found Ilvermorny with her Muggle husband James Steward and adopted sons Chadwick and Webster Boot. Tracking her down, Gormlaith attempted to kill the couple and take their daughters with her, but was killed by a poisoned arrow from the Pukwudgie William in the duel that followed.[10]
Corvinus Gaunt had a hand in helping install an elaborate plumbing system within Hogwarts, which placed the secrecy of the Chamber of Secrets at risk. Having inherited the right to know the location of the Chamber's trapdoor entrance, he concealed the trapdoor behind plumbing fixtures and a sink.[11]
Marvolo Gaunt was obsessed with being pure-blood and certain of his superiority over those of "lesser" blood status, despite living in poverty. He considered that his blood purity made him practically royal, and disowned his daughter Merope for supposedly being a Squib and coercively marrying a Muggle, Tom Riddle Senior.[9]
Malfoy family The Malfoys' family motto means "purity always conquers" in Latin. As such they were best known for a command of political influence and respect that flourished with their traditional tendency for courtship with richness and power around them. They are known for their disdain of Muggles and Muggle-borns.[12][13][14] While they strongly believe in the concept of blood purity, they did not take it to the interbreeding extremes, thus allowing half-bloods to appear on their family tree.[2][3]
Nicholas Malfoy was widely believed to have dispatched many Muggle tenants in the late 1340s, under the guise of the Black Death. However, this was never proven, but it was likely because he escaped censure by the Wizard's Council, and therefore was never punished.[3]
Lucius Malfoy I was an aspirant for the hand of Elizabeth I. Although never proven, it was widely believed that her opposition towards marriage was due to a jinx that he left on her in retaliation for his unsuccessful attempt to woo her.[3]
Brutus Malfoy was editor of the anti-Muggle periodical Warlock at War, which ran during the 1670s. With the persecution of wizards in Muggle supremacy having reached its height, he campaigned to compare blood traitors to Squibs, stating in 1675 that "nothing is a surer sign of weak magic than a weakness for [Muggle] company".[15]
Septimus Malfoy was Advisor to the Minister for Magic from 1789 to 1798.
Abraxas Malfoy was suspected of being part of a plot that forced Nobby Leach, the first Muggle-born Minister for Magic, to leave the post prematurely in 1968.
Lestrange family The Lestranges were an ancient pure-blood wizarding family, and one of the Sacred Twenty-Eight. Many Lestranges practise the Dark Arts and believe in the notion of pure-blood supremacy, disdaining Muggles and Muggle-borns. They also have many Death Eater family members.
Greengrass family The Greengrasses were known to have espoused the philosophy of pure-blood supremacy.
Following the horrors of the Second Wizarding War Astoria Greengrass abandoned the beliefs of blood supremacy in favour of a more tolerant world view. She even refused to raise her son to believe that "Muggles [are] scum", even though that created tension with her parents-in-law, Lucius and Narcissa Malfoy.
Durmstrang Institute Durmstrang did not allow Muggle-borns to attend,[16] though, unlike most other examples of "pure-blood elitism" listed here, they did not seem to have a violent, murderous, or destructive attitude towards Muggle-borns and Muggles either (and indeed, some individual students such as Viktor Krum were more tolerant and accepting of Muggle-borns).
Death Eaters Possibly the largest and most destructive Muggle haters and blood purity fanatics of their time (if not of all time). Led by Voldemort, who thought that magical blood was pure and special. Under their regime, Muggle-borns were stripped of their wands and reduced to beggars,[17] or alternatively, if unable to prove relations to any wizard in kangaroo courts overseen by Dolores Umbridge,[18] they were subjected to the Dementor's Kiss or else imprisoned in Azkaban. Meanwhile, Muggles were killed indiscriminately and seen as nothing but slaves or cattle. Ironically, however, Voldemort himself was half-blood, his mother being a pure-blood witch and his father a Muggle.[19]
Lord Voldemort
Dolores Umbridge Umbridge hated Muggles, Muggle-borns, as well as half-breeds and had no problem throwing in with the Death Eater's blood purity obsessed worldview (despite hypocritically being herself a half-blood, although she did lie about being pure-blood).[20] She was head of the Muggle-Born Registration Commission during Voldemort's control of the Ministry and actively persecuted "Mudbloods", stripping them of their wands.[18] After Voldemort's defeat, she was arrested and sentenced to Azkaban for life for her crimes against Muggle-borns.
Salazar Slytherin Slytherin did not accept Muggle-borns in his house and subsequently ended his friendship with Godric Gryffindor. He left a Basilisk in a hidden chamber beneath Hogwarts so that it could one day "purge the school of all who were unworthy to study magic".[21][22]
Elizabeth Burke Elizabeth Burke seemed to have hated Muggle-borns, as her portrait at Hogwarts Castle encouraged Slytherins to be "nasty to Mudbloods".[23]
Yaxley family A Yaxley in the 1920s placed great emphasis on the importance of pure-blood and was disliked by Leta Lestrange for how he made a beeline towards her simply for being a member of an aristocratic and ancient pure-blood clan.
Lysandra Yaxley married into the pure-blood elitist House of Black.
Corban Yaxley refused to marry refused to marry anybody who was not a pure-blood.
Barrett Fay Barrett was a wizarding author who placed immense importance on the supremacy of pure-blood wizards, having written at least two books on the subject: ''Mudbloods and How to Spot Them and When Muggles Attack.

Pure-blood bias[]

"Your mother was Muggle-born, of course. Couldn't believe it when I found out. Thought she must have been pure-blood, she was so good."
— Horace Slughorn showing bias[src]

Some wizards, while believing somewhat in the inherent superiority of pure-bloods, do not actively discriminate against or show hostility to Muggle-borns and are even fond of them in some cases.

“Pure-blood bias” Reason(s)
Horace Slughorn Although Slughorn thought that pure-bloods were normally more magically skilled, he is aware that half-bloods and Muggle-borns have much to offer, and nonetheless had many talented Muggle-borns in his Slug Club, including Lily Evans and Hermione Granger. He even wanted Lily Evans to be in his house of Slytherin.[24]
Cornelius Fudge Fudge showed great favouritism toward influential pure-bloods such as the Malfoys.[25] However, until 1995, he relied heavily on the counsel of Albus Dumbledore, a supporter of Muggle rights, as well as was very polite to Harry Potter, a half-blood (at least initially). He also had a cordial, if somewhat patronising, relationship with the Muggle Prime Minister and was highly distraught at the gruesome murder of twelve Muggles earlier in his days at the Ministry.[26] However, Fudge allowed the passage of anti-half-breed legislation, ennabled the cruelty of Dolores Umbridge (herself an extreme case of pure-blood supremacy), and his pro-pure blood attitude and policies as Minister were cited as major flaws of his and the reason why his administration ultimately failed. Albus Dumbledore had the belief that Fudge believed too much in the importance of blood purity.[27]
Severus Snape During his time at Hogwarts, Severus fell in with a group of future Death Eaters in his desire for power and acceptance.[28] Despite his childhood claim that blood status didn't matter,[29] he began to use the term "Mudblood" to describe Muggle-borns. However, an accidental application of the term during an argument towards Lily Evans ended their friendship.[30] Snape was upset by this, and attempted to atone for using the remark and being prejudiced by becoming a double agent for Albus Dumbledore,[29] however, he was still supportive of actions of many pure-blood elitists, for example by often being cruel to muggle-born Hermione Granger and favouring the poor attitudes and behaviours of pure-blood Slytherins. Due to these combinations of actions, however, Snape is a somewhat ambiguous case.

Behind the scenes[]

  • It is unknown if Muriel could be considered biased, as she once condescendingly referred to Hermione Granger as "the Muggle-born" at her nephew's wedding. However, as Ron pointed out, she was rude to everyone. She also made snide remarks about Fleur Delacour, who was Quarter-Veela, but these remarks really were not about her blood status, but were because she was French.[31] However, whether Muriel was aware of Fleur being a quarter-Veela is not revealed.
  • According to JK Rowling, when asked about the term given for the magical offspring of one magical and one non-magical parent, she said that non-bigots in the wizarding world would say "half-blood", while pure-blood supremacists would say "mudblood".[32]
  • Parallels have been drawn between pure-blood supremacy and the Death Eaters and Nazis and their belief in Aryan race supremacy.[33]
