J.K. Rowling assigned Harry Potter’s rival Draco Malfoy to Slytherin house.
Draco is sorted into Slytherin when he begins at Hogwarts in Harry Potter and the Philosopher’s Stone. He comes from a wealthy wizarding family and initially treats Hogwarts status, ancestry, and influence as important measures of worth. His father, Lucius Malfoy, is associated with Voldemort and the Death Eaters.
Slytherin is one of Hogwarts’ four houses and was founded by Salazar Slytherin. Its traditional qualities include ambition, resourcefulness, determination, and cleverness. The books often show that a house’s reputation does not fully define every student in it.
Draco remains a rival to Harry through much of the series, but his later story becomes more complicated. Under pressure from Voldemort, he is ordered to carry out dangerous tasks and struggles with fear, family expectations, and the consequences of dark allegiance.
