Pure-blood

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

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, others such as the Gaunts, Lestranges, and Blacks, required their family to only marry pure-blood individuals, or those with no Muggle or Muggle-born ancestors. This refusal of marrying Muggles or Muggle-borns had led to difficulty in propagating their families.

## Overview

Pure-blood individuals are people who have no Muggles or Muggle-borns as parents or grandparents. Traditionalist pure-bloods like to keep the generations "pure" by breeding with other pure-bloods and are generally the ones who use the term 'Mudblood', a term considered derogatory by the wizarding world. Families of pure-blood status often avoid marrying their heirs off to Muggle-Borns and Half-Bloods, believing that the next generation could lose their capability to perform magic. Mudblood means Muggle-born, suggesting they have dirty blood and thus have no right to be a witch/wizard. Pure-bloods who do not share these prejudices are considered "blood traitors" by the ones that do. 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 can trace their pure-blood status through many generations of magical ancestors and deny ever having any Muggles 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 if they ever did exist in the past, true pure-blood wizards and witches do not exist today. They merely erase Squibs, Muggle-borns, and Muggles from their family trees.

Half-bloods who consider blood purity very important also hide their Muggle ancestry, clinging to the magical heritage they do have. Many Death Eaters are 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 question Riddle's 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, practise marrying cousins in order to maintain their pure-blood status, and disown any members who marry someone who is not a pure-blood. This practice has been known to cause problems as families often become inbred because of this; for example, the Gaunts showed signs of violent tendencies, mental instability, and being enfeebled. The number of pure-bloods has diminished over time because of said inbreeding.

## Attitude

Some pure-bloods regard themselves as superior to those witches and wizards who are born to Muggles and half-bloods. They believe that Muggles are little more than animals and that Muggle-borns, whom they derisively call 'Mudbloods', are second-class citizens, inferior and unworthy of being allowed to practise magic. Many also discriminate against half-breeds giants, werewolves and magical creatures.

Salazar Slytherin believed that only pure-bloods should be allowed to attend Hogwarts School of Witchcraft and Wizardry and educated in magic; this was the cause of his conflict with the other Founders and his leaving 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 Muggle-born students. Lord Voldemort 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.

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 rid it of Muggle-borns. When Voldemort 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. 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.

However, there are pure-bloods who do not have these beliefs, and instead treat all magical people and Muggles as equals. These pure-blood folk are often labelled "blood traitors" by the more fanatical pure-bloods.

### Possible pure-bloods

Due to their affiliation to Slytherin and Lord Voldemort, many wizards and witches may be considered pure-bloods. Others have openly express their prejudice toward Half-bloods and Muggle-borns, which is another reason to believe they are pure-blood supremacist. Some even become Death Eaters.
