Pure-blood

**Pure-blood** was the term for wizarding families who claimed to have no Muggles, Squibs, Muggle-borns, or half-bloods in their family tree; however, when traced back far enough, nearly every family tree had a few non-magical ancestors. Most wizards and witches considered an individual to be a pure-blood if his or her parents and grandparents were not Muggles, Squibs, or Muggle-borns.

By 1995, the number of pure-blood families were declining. Most pure-blood families were related by then in an effort, by some, to retain their status by marrying only other pure-blood families, but it had eventually led to inbreeding. While some families, such as the Malfoys, had allowed for marrying half-bloods, many others such as the Gaunts, Blacks, and Lestranges, required their family to only marry pure-blood individuals, or those with no Muggle, Muggle-born, or Squib ancestors, in order to maintain their “pure” bloodline. This refusal of marrying Muggles or Muggle-borns had led to difficulty in propagating their families

## Overview

Pure-blood individuals were people who had no Muggles, Muggle-borns, or Squibs as parents or grandparents. Traditionalist pure-bloods loved and strove to keep all the future generations "pure" by breeding with other pure-bloods, and were generally the ones who used the term "Mudblood" against Muggles, Muggle-borns, Squibs, and even half-bloods, a term considered highly derogatory by the Wizarding world. Families of pure-blood status often avoided marrying their heirs off to Muggles, Squibs, Muggle-borns, and half-bloods, believing that the next generation could lose their capability to perform magic.

In the 1930s, a wizard, commonly believed to be Cantankerus Nott, wrote the *Pure-Blood Directory* featuring twenty-eight families he believed to be truly pure-blooded, though many objected to this designation.

## Maintaining "purity"

Some pure-blood families could trace their pure-blood status through many generations of magical ancestors and deny ever having any nonmagical ancestors within the family, such as the House of Black, the motto of which is "Toujours pur", meaning "Always (or Still) Pure". However, the truth is that even if they did exist in the past, true pure-blood wizards and witches did not exist in the present day, as Squibs, Muggle-borns, and half-bloods were too common. These pure-blood families simply erased all Muggles, Squibs, and Muggle-borns from their family trees.

Half-bloods who considered blood purity very important also hid their Muggle ancestry, clinging only to the magical heritage they did have. Many Death Eaters were believed to have done this, and their leader himself took on the name Lord Voldemort out of a desire to not keep the name of his "*filthy Muggle father*". It is likely that Voldemort told his followers he was a pure-blood, or that most of the Death Eaters knew better than to dare question his blood status, given the reaction of Bellatrix Lestrange to Harry's "accusation" that he was in fact a half-blood.

Many pure-blood families, such as the Blacks and Gaunts, practised marrying their own cousins in order to maintain their pure-blood status, and disowned any members who married someone who was not a pure-blood. This practice had been known to cause problems as families often became inbred because of this; for example, the Gaunts showed signs of violent tendencies, mental instability, and being enfeebled. The number of pure-bloods had diminished over time because of said inbreeding.

## Attitude

Some pure-bloods regarded themselves as superior to those witches and wizards who were born to Muggles and half-bloods. They believed that Muggles were just little more than animals and that Muggle-borns, whom they derisively called "Mudbloods". Mudblood itself was a highly pejorative term suggesting that Muggle-borns were inferior to pure-bloods and that they were supposed to be "second-class citizens", had “dirty” blood and were a big disgrace to the wizarding world, and thus had no right to be a witch/wizard and unworthy of being allowed to practise magic. Many also discriminated against half-breeds, giants, werewolves and magical creatures. Pure-bloods who did not share these prejudices were considered "blood traitors" by the discriminatory ones that do.

Salazar Slytherin believed that only pure-bloods should be allowed to attend Hogwarts School of Witchcraft and Wizardry and be educated in magic; this was the cause of his conflict with the other Founders and his permanent departure from the school. However, he left behind the Chamber of Secrets in the hope that one day his heir would open the Chamber and release the basilisk within to target all the Muggle-born students. Tom Riddle was this heir, and the basilisk petrified several Muggle-born students in 1943 and the 1992–1993 school year and managed to kill one student, Myrtle Warren, in 1943.

Half-bloods who also considered blood purity very important also denied their Muggle ancestry, clinging only to the magical heritage they did have. Tom Marvolo Riddle, for example, took on the name Lord Voldemort out of a desire to not keep the name of his *"filthy Muggle father"* and also called Harry Potter's mother *"filthy Muggle mother."*

Riddle, later known as Lord Voldemort, continued his persecution of those who were not pure-bloods (ironically being a half-blood himself) with his followers, the Death Eaters. They strove to place pure-bloods in control of the wizarding world and to eventually rid it of Muggle-borns entirely. When Voldemort temporarily succeeded in taking over the Ministry of Magic during the height of the Second Wizarding War, his followers created the Muggle-Born Registration Commission in order to weed Muggle-borns out of the population and send them to Azkaban for allegedly stealing magic for not being pure-blood. Pure-bloods were also blatantly favoured within the Ministry and, to a lesser extent, Hogwarts School of Witchcraft and Wizardry, although half-blood was sufficient to avoid prosecution. This oppression was eventually ceased after Voldemort's final death when Kingsley Shacklebolt became the new Minister for Magic.

However, there were pure-bloods who did not have these beliefs, and instead treated all magical people and Muggles as equals (for instance the Weasleys). These pure-blood folk were often labelled as "blood traitors" by the more bigoted pure-bloods. There were also a few pure-bloods who were still fanatical, but also more lax about marriages and allowed their family members to marry Half-bloods, for example the Malfoys.

### Possible pure-bloods

Due to their affiliation to Slytherin and Lord Voldemort, many wizards and witches might be considered pure-bloods. Others had openly expressed their prejudice toward half-bloods and Muggle-borns, which is another reason to believe they were pure-blood supremacists. Some even became Death Eaters.
