Harry Potter is a series of fantasy novels written by British author J. K. Rowling. The novels chronicle the lives of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's struggle against Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic, and subjugate all wizards and Muggles (non-magical people).
(According to Wiki: https://en.wikipedia.org/wiki/Harry_Potter)
Hogwarts School of witchcraft and wizardry was divided into four houses, each bearing the last name of its founder: Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin.
Houses at Hogwarts were both the living and learning communities for its students. Each year's group of students in the same house shares the same dormitory and many classes. The houses compete throughout the school year, by earning and losing points for various activities. The house with the most points wins the House Cup. Each house also has its own Quidditch team that competes for the Inter-House Quidditch Cup. These two competitions breed rivalries between the houses, the greatest of which is that between Gryffindor and Slytherin. (According to http://harrypotter.wikia.com/wiki/Hogwarts_Houses )


Godric Gryffindor
- One of the four Hogwarts founders. His sword may present itself to a worthy Gryffindor in times of need
- Godric was known for his bravery, and his skills as an accomplished dueller. He even had a special swordcreated for him by Ragnuk the First, the finest of the goblin silversmiths.
-Legend has it that Godric was also the man who gave Hogwarts the Sorting Hat, a sentient piece of headwear that soon became the one to sort the school’s students into houses
-Godric will always be known for his accomplished skills in battle, and his fight against Muggle discrimination in the wizarding world. In fact, it was a serious argument between Godric and Salazar that finally made the Slytherin founder leave Hogwarts. (Source: https://www.pottermore.com/features/stories-of-the-hogwarts-founders)

- One of the four Hogwarts founders. He was a famous Parselmouth who built the Chamber of Secrets
-For many years, all was well among the four founders. Yet when shrewd Salazar Slytherin, ‘from fen’, suggested that only those from magical families deserved to come to Hogwarts, his three friends stood against him.
-Salazar Slytherin left the school. Before he did however, he built a secret room inside the castle with a great statue of himself and a monster inside that only he could control.
-The chamber would remain a secret, until Salazar Slytherin’s heir came to Hogwarts, ready to finish his ancestor’s work. Slytherin also left behind a golden locket, which would become a treasured family heirloom, and eventually a Horcrux of Lord Voldemort too.
-Despite his flaws, Salazar was a talented wizard, skilled in Legilemency and Parseltongue, and his twisted legacy and talents lived on through many members of his bloodline, specifically Lord Voldemort. (Source: https://www.pottermore.com/features/stories-of-the-hogwarts-founders )

Salazar Slytherin

-One of the four Hogwarts founders. Her portrait can be seen in the Hufflepuff common room toasting her students with her golden cup
-Helga, ‘from valley broad’, was the founder of the house which valued those that were ‘just and loyal’. According to the Sorting Hat, Helga vowed to ‘teach the lot’ – and didn’t judge certain students over others, no matter how much talent they had or what families they came from.
- Hufflepuff was known for her talents in Charms, and used her remarkable skills for preparing food – a speciality of hers – to create splendid feasts that were enjoyed by all. Her talent would bring the whole school together in harmony.
-And as for that golden cup? Well, that very cup would be passed down to Helga’s descendants, eventually falling into the hands of one Hepzibah Smith, a ‘distantly descended’ witch with a penchant for possessing valuable trinkets. Unluckily for her, a young fellow called Tom Riddle was well aware of this, and once he had hold of it, Helga’s trusty cup engraved with a badger would become one of Lord Voldemort’s Horcruxes.

Rowena Ravenclaw
-One of the four Hogwarts founders. She wore an enchanted diadem, which was stolen by her daughter
-Rowena Ravenclaw,
from glen’, was the most brilliant witch of her time, but her story is one of tragedy. Known for her wit and love of learning, she wore a diademthat was said to grant wisdom to the wearer.
However, Rowena’s own daughter grew jealous of her mother’s incredible intelligence. Helena Ravenclaw stole her mother’s diadem and ran away, a fact that Rowena kept hidden from her fellow founders even when she fell ill.
-Rowena sent a man to bring Helena home. Unfortunately, that man was the Bloody Baron, who was head over heels with Helena, and stabbed her in a rage when she refused to come home. After Helena was tragically killed, legend tells us that Rowena Ravenclaw died of a broken heart. No wonder Helena’s ghost, that became Ravenclaw’s house ghost, would often roam the corridors in silence. (Source: https://www.pottermore.com/features/stories-of-the-hogwarts-founders )
