Slytherin House was founded by Salazar Slytherin. Salazar's requirements were that you had to be ambitious, powerful, cunning, resourceful, and vane. Slytherin, unlike the other three founders, only wanted to admit pure-blood wizards into Hogwarts. Gryffindor, finally getting sick of hearing Salazar, got into a fight with him, and Slytherin left Hogwarts forever. Slytherin's head of house is Severus Snape, the ghost is the Bloody Baron, and the colors are green and silver. Slytherin is represented by a striking snake. Slytherin is also famous for creating the legendary Chamber of Secrets, where it is told he sealed a monster that would one day clear Hogwarts of all the muggleborns.
