One of the four Hogwarts houses, Gryffindor was founded by Godric Gryffindor and favoured students who possessed characteristics such as courage, bravery and determination. The house colours were scarlet and gold, and the emblematic animal was a lion, which decorated the walls of the Gryffindor common room. Gryffindor alumni included all seven Weasley children, Harry Potter, Hermione Granger, all four Marauders and Albus Dumbledore. Gryffindor students embraced a long held rivalry with Slytherin house although they were largely friendly with Ravenclaw and Hufflepuff students.
