Founded in the 10th century by Godric Gryffindor, Rowena Ravenclaw, Helga Hufflepuff and Salazar Slytherin, Hogwarts was established in the Highlands of Scotland to educate young wizards and witches as well as to keep students safe from muggle persecution. Theory has it that Rowena Ravenclaw came up with the name of Hogwarts after dreaming of a warty hog that led her to a cliff by a lake.^[5] Since then, Hogwarts educated most wizarding children in the United Kingdom and its surrounding areas, keeping its location hidden from other wizarding schools and muggles.
