blood purity
Untainted family descent
Blood purity is the concept that ancestry or lineage can be contaminated by mixture with other groups—typically racial, ethnic, or religious.
The term appears in historical contexts like Nazi ideology and Spanish *limpieza de sangre*, where "pure" bloodlines supposedly conferred superiority or rights.
In the Harry Potter series, blood purity distinguishes wizards with magical ancestry from those with non-magical ("Muggle") parentage: The Death Eaters were obsessed with blood purity.
The concept has no scientific basis—human genetics doesn't work this way.
