Hogwarts School of Witchcraft and Wizardry has four distinct houses, Gryffindor, Ravenclaw, Hufflepuff, and Slytherin.

Slytherins have the worst reputation of all the houses in the 'Harry Potter' series. There were many witches and dark wizards who came out of Slytherin.

The emblem of Slytherin is a green serpent and the official house colors are emerald green and silver. Dark magic and pure-blood ideologies are associated with the Slytherins house.

Slytherin is one of the houses among the four distinct houses at the Hogwarts School of Witchcraft and Wizardry. Salazar Slytherin was the founder of this house.

The house was founded by Salazar Slytherin and is composed mostly of pure-bloods (whose mother and father are from wizarding families). As the founder, Salazar Slytherin does not trust muggle-born witches and wizards.

So, to be a part of this house, he instructed the Sorting Hat to select students who have characteristics like ambition, leadership, resourcefulness, and are cunning. Here are some unknown Slytherin facts that every 'Harry Potter' fan should know.

History And Founder Of Slytherin

Hogwarts was founded a thousand years ago by four founders, Godric Gryffindor, founder of Gryffindor house, Helga Hufflepuff, founder of Hufflepuff house, Rowena Ravenclaw, founder of Ravenclaw house, and Salazar Slytherin, founder of Slytherin house. There was peace between the co-founders for many years after Hogwarts was built.

The pressure to admit pure-blood wizards to Slytherin affected the other three founders tremendously, and it especially affected Gryffindor. It created great controversy and civil war between the houses at the school.

Slytherin later decided to leave the school and never returned. Let's have a look at some interesting facts about Slytherin's history.

Salazar Slytherin founded the house and it was strictly instructed by him that the house should be composed only of pure-blood students.

The Sorting Hat is one of the cleverest, most intelligent, and sentient magical hats. It can decide the placement of students to one of the four houses based on their qualities.

'Pureblood' is the password to enter the Slytherin common room, which was discovered when Harry and Ron used Polyjuice potion to sneak inside.

During their enrollment, students attending Hogwarts have the opportunity to terminate their magical education at certain points.

When Slytherin left Hogwarts, he left the Chamber of Secrets behind, intending to reopen it one day. The Chamber of Secrets was opened twice by others. Finally, Harry Potter killed the serpent of Slytherin when the Chamber of Secrets was opened for the second time in 1992.

Salazar's locket didn't end up in Tom Riddle's hands, it was handed down to Voldemort's mother, who stole the locket and sold it to Borgin and Burkes.

To identify students who are from house Slytherin, they must have the crest embroidered on their robes, and the mantle is decorated with a portrait of a serpent in the common room.

The Slytherin common room is also known as Slytherin Dungeon. The common room of Slytherin is located in the Hogwarts dungeons, beneath the black lake. It serves as the common room only for Slytherin students. The common room has many low-backed black and dark green leather sofas with greenish lamps, dark wood cupboards, skulls, and buttons.

The common room password changes every fortnight, when it is posted on the noticeboard.

Technically, Peeves is not a ghost at all, as he was a poltergeist. This is a person whose energy gathers and forms from external stimuli.

Traits And Reputation

Draco Malfoy's gang, Merula Snyde's gang, Pansy Parkinson's gang, and the death eaters are a few Slytherin students who clique together and acquire leaders, which are later illustrated as Slytherin's ambitious qualities. Slytherins tend to hesitate before acting, which means they have highly developed senses of self-preservation.

Slytherins have other characteristics like unrequited, deep love. The feeling can be seen for Lily Evans and Helena Ravenclaw by Severus Snape and the Bloody Baron.

Slytherins tend to possess strong leadership skills, intelligence, cunning, and taking charge, and are achievement-oriented and loyal.

Slytherin's emblem animal is a green serpent and the house's colors are green and silver. The serpent is the animal guardian of the house.

All Hogwarts houses have a connection to a special element. Water is the main element of Slytherin. The fluidity and amorphousness represent the traits and actions of water. The serpent is commonly associated with lochs, which are often green, and silver is often associated with gray rainwater.

An Irishwoman, Isolt Sayre, one of Slytherin's descendants, founded the School of Witchcraft and Wizardry in Ilvermorny.

Salazar Slytherin did not believe that wizards and witches were born of muggle parents; hence, Godric Gryffindor raised his voice to fight for muggle rights within the wizarding community.

As per 'Harry Potter' mythologies, Hogwarts is the most haunted location globally and has a house ghost that acts as a mascot. Four different ghosts represent each of the four houses.

Gryffindor has the ghost of Nearly Headless Nick, Ravenclaw's ghost is Helena Ravenclaw, the daughter of house founder Rowena Ravenclaw, Hufflepuff's ghost is the Fat Friar, and Slytherin's house ghost is the Bloody Baron.

Not all Slytherins are evil and Slytherin's list of alumni is impressive. According to the final book in the series, Harry Potter's son Albus Severus was sorted into Slytherin upon arriving at Hogwarts.

House Head

Each house has a head professor at Hogwarts. The professor's responsibility is to look after and punish the students of their house. The headmaster, Albus Dumbledore, chooses a professor who possesses all the qualities required for each post.
