The founder of which Hogwarts House believed that pureblood wizards were superior to all others?
Answer Slytherin
Salazar Slytherin thought only pureblood wizards should be allowed to go to school at Hogwarts. (Sorry, Hermione.) He believed in this twisted idea so much that it caused him to clash with the other Hogwarts founders, most notably Godric Gryffindor. It also inspired him to build the Chamber of Secrets, inside of which he stashed a basilisk that would one day be unleashed to murder all the Muggle and half-blood students at Hogwarts once and for all. (Really sorry, Hermione.) During his second year, Harry Potter defeats the basilisk once and for all.
