Severus Snape

Professor Severus Snape (Born January 9th 1960) was an English half-blood wizard serving as Potions Master (1981-1996), Head of Slytherin House (1981-1997), Defence Against the Dark Arts professor (1996-1997), and Headmaster (1997-1998) of Hogwarts School of Witchcraft and Wizardry as well as a member of both the Order of the Phoenix and a Death Eater. His double life played an extremely important role in both of the Wizarding Wars against Voldemort.

The only child of Muggle Tobias Snape and pure-blood witch Eileen Snape (née Prince), Severus was raised in the Muggle dwelling of Spinner's End, which was in close proximity to the home of the Evans family, though in a poorer area. He met Lily and Petunia Evans when he was nine. He fell deeply in love with Lily upon their meeting and became a close friend of hers.

Severus started at Hogwarts with Lily in the 1971–1972 school year, where he was Sorted into Slytherin House. This put him in the same year as Lily but unfortunately for him she was Sorted into Gryffindor House. Severus became the immediate enemy of James Potter and Sirius Black and was a frequent victim of their bullying. This led him to be irritable towards James's son Harry when he was a professor. Snape, when young, developed a passion for the Dark Arts, which increased as his desire for revenge against his bullies grew stronger.

Snape became acquainted with a group in Slytherin House, many of whom were pure-blood supremacists. This put his friendship with Lily, a Muggle-born, under great strain until it was eventually broken in their fifth year. In a misguided attempt to win back Lily's affections, Snape joined the Death Eaters along with a group of his fellow Slytherins.

Severus was made a member of the Slug Club presumably because of his talent in Potion-making. Horace Slughorn even kept a picture of him as a student, clutching his copy of Advanced Potion-Making. However, Horace did not actually have many hopes for Severus's future, as his photograph was kept behind many others.

As an active Death Eater, one of Snape's biggest contributions was letting Lord Voldemort know about the prophecy Sybill Trelawney made to Dumbledore. This part of the prophecy could have applied to either Harry Potter or Neville Longbottom, who was also born at the end of July 1980 to parents who were members of the Order. Once Lord Voldemort decided to target the Potters over the Longbottoms, Snape begged Voldemort to at least spare Lily. Voldemort ostensibly agreed, but did not actually follow through on this promise due to Lily's refusal to allow him to kill Harry, resulting in her sacrificing her life to save her son's.

Shortly before Lily Evans was murdered by Lord Voldemort, Snape changed sides and became a member of the Order of the Phoenix as well as a double agent during the Second Wizarding War. With tremendous difficulty, Snape prevented Voldemort from learning the truth about his loyalties.

Despite the opinions of most others including Harry during his early life, Albus Dumbledore trusted Snape for reasons that were kept between them both until their deaths. Despite Snape killing Dumbledore, it is learned that they had a special agreement for him to do so. When he died, it was revealed that his deep strong love for Lily Evans caused him to redeem himself, joining Dumbledore's cause for her protection (and, after her death, that of her son) from Lord Voldemort.

The relationship between Dumbledore and Snape would be one of unusually strong loyalty, so much so that Snape agreed to kill Dumbledore upon the latter's own request. Before Dumbledore's death, Snape promised to protect the students of Hogwarts from the Death Eaters, who would inevitably take control of the Ministry of Magic as well as the school.
