Hogwarts founders

The Hogwarts Founders
Hogwarts school was founded over a thousand years ago by four of the most brillant witches and wizards of the time. Godric Gryffindor, Salazar Slytherin, Helga Hufflepuff and Rowena Ravenclaw laid the foundations for the only Wizarding school in Britain.

Godric Gryffindor - The founder of Gryffindor house. A fair man, he believed that any child who displayed magical abilities before their 11th birthday should be able to attend Hogwarts. Godric valued courage and bravery, believing these were the two most virtuous abilities a person can possess.

Salazar Slytherin - The founder of Slytherin house, he was sly and cunning, not unlike many of the students in his house today. He believed strongly that only wizards of pure blood (i.e., those with a mother and father from Wizarding families) should be allowed to attend Hogwarts. Slytherin caused great dispute over this with the other founders, and it eventually caused a permanent rift with Gryffindor, which led to Slytherin's departure from the school. Before he left, however, he created the Chamber of Secrets, complete with a huge statue of himself and a horrible monster.

Helga Hufflepuff -The founder of Hufflepuff house, she was a kind and warm woman. Not much is known of her, though we may assume that she brought (or tried to bring) unity to Hogwarts. The values a person must possess to be sorted into Hufflepuff house are those of loyalty and patience above all else.

Rowena Ravenclaw - The founder of Ravenclaw house, she was a sharp and intelligent woman. Intellect is a highly valued asset to the students of Ravenclaw house. Due to this, it is likely that Rowena wanted to make Hogwarts the very finest Wizarding school on earth, teaching those children with the highest intelligence.

After Hogwarts was built, the founders coexisted peacefully for many years. Eventually, however, the pressure from Slytherin to admit only pure-blooded wizards affected the other three founders greatly, and none more than Gryffindor. Slytherin finally left Hogwarts following a massive argument with Gryffindor over the issue, and he never returned.
