Which Hogwarts house did J.K. Rowling say was founded by Helga?

J.K. Rowling’s Harry Potter stories say that Helga Hufflepuff founded Hufflepuff House. She was one of Hogwarts’s four founders, alongside Godric Gryffindor, Rowena Ravenclaw, and Salazar Slytherin.

Hufflepuff is associated with loyalty, fairness, hard work, patience, and an inclusive attitude. Its house colours are yellow and black, and its emblematic animal is the badger. The house’s ghost is the Fat Friar, while Pomona Sprout is its long-serving head of house during much of Harry’s time at school.

The founders established the four houses to organize students according to qualities each valued. Rowling’s books make clear that the houses are not simple measures of goodness or ability: students can show traits linked with several houses. Helga Hufflepuff is also connected to a cup that later becomes one of Voldemort’s Horcruxes.
