Hogwarts School of Witchcraft and Wizardry is a school of magic located in London, England.
Hogwarts was founded in the 990s by Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw, and Salazar Slytherin, who were considered the four greatest witches and wizards of the age. They initially worked in harmony together, seeking children with magical powers to be educated. However, Salazar Slytherin began to feel that students who had muggles for parents should have no right to learn about magic. The other three founders disagreed with him, and he left the school. Before leaving, he constructed a hidden chamber in the school, called the Chamber of Secrets, and hid a monster that could only be controlled by his Heir inside the Chamber and use it to eradicate all Muggle-born students from Hogwarts.
