Hufflepuff is one of the four Houses of Hogwarts School of Witchcraft and Wizardry. Its founder was the medieval witch Helga Hufflepuff. The Head of Hufflepuff is Pomona Sprout. The Fat Friar is the House's patron ghost. Hufflepuff is the most inclusive among the four houses; valuing hard work, patience, loyalty, and fair play rather than a particular aptitude in its members. Its emblematic animal is the badger, and yellow and black are its colours.
Hufflepuff corresponds roughly to the element of earth, and it is for that reason that the House colours were chosen: yellow represented wheat, while black was emblematic of soil. The Hufflepuff points hourglass contains yellow diamonds  Students belonging to this house are known to be hard-working, friendly, loyal, honest and rather impartial. It may be that due to their values, Hufflepuffs are not as competitive as the other houses, or are more modest about their accomplishments.
Hufflepuff appears to have the least rivalry with the other houses, except in Quidditch, although the Triwizard Tournament did temporarily put a great deal of strain on the relationship between Gryffindor and Hufflepuff, due to unusual circumstances of the selection of both Gryffindor student Harry Potter and Hufflepuff student Cedric Diggory as Champions. According to Minerva McGonagall, all four of the houses have produced exceptional witches and wizards in their time, but due to Helga Hufflepuff's policy of accepting any student and its usually poor performance in the House Cup, Hufflepuff is often thought to be the house of less talented wizards. However, this is merely a misunderstanding of theSorting Hat's poem. The Hufflepuff house has produced a great many of successful and influential members of the wizarding world.
Hufflepuff has produced the fewest number of dark wizards than any other house atHogwarts. Their cheerful and friendly demeanor can probably account for this property of the House. Hufflepuff firmly demonstrated its loyalty during the Battle of Hogwarts in 1998, when they were second only to Harry Potter's own house ofGryffindor in the number of students willing to stay and fight against Voldemort andhis forces in the defence of their school.
