I’ll have pure blood thanks
The term 'pure-blood' refers to a family or individual without Muggle (non-magic) blood. The concept is generally associated with Salazar Slytherin, one of the four founders of Hogwarts School of Witchcraft and Wizardry, whose aversion to teaching anybody of Muggle parentage eventually led to a breach with his three fellow founders, and his resignation from the school.WHERE THE TERM 'PURE-BLOOD' ORIGINATED FROM
The ancient and highly prejudiced pure-blood
Malfoy family
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.
[1][2][3] Most wizards and witches considered an individual to be a pure-blood if his or her parents and grandparents were not Muggles or Muggle-born.
[4]
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.
[2][1] This refusal of marrying Muggles or Muggle-borns had led to difficulty in propagating their families.
