'I can teach you how to bottle fame, brew glory, even stopper death -- if you aren't as big a bunch of dunderheads as I usually have to teach."
-- Severus Snape
Severus Snape was Potions Master, Defense Against the Dark Arts teacher, and Head of Slytherin at Hogwarts School of Witchcraft and Wizardry; he succeeded Dumbledore as Headmaster. He was personally killed by Lord Voldemort and his snake, Nagini.
Snape was a conundrum to all who know him: sarcastic and hard on his most vulnerable students, yet respected by his colleagues; Dumbledore’s confidante and healer, yet also apparently his murderer. Although he was a Death Eater at one time, he became a member of the Order of the Phoenix working secretly against the Dark Lord after meeting with Dumbledore on the Windy Hilltop in 1980 to warn him of an impending attack on the Potter family. Snape’s regret over the death of his lost love, Lily Evans, kept him going as a double spy till the end of his life.
Severus Snape was the half-blood only child of Tobias Snape (a Muggle), and Eileen Prince Snape (a witch). The Snape household on Spinner’s End in an industrial part of northern England was not a happy one. Tobias Snape frequently unleashed his anger on his wife, and Severus, their wizard child, was neglected or worse. When he was about 9 years old, young Severus discovered another magically gifted child at the neighborhood playground, and fell in love with green-eyed Lily Evans’s generous nature and her daring — and tried to forget that she was a “Mudblood,” a Muggle-born witch. In spite of her blood status, he innocently hoped they would both be put in Slytherin House, which he believed was house for the brightest students like themselves.
Severus and Lily attended Hogwarts together from 1971 to 1978, but Severus was sorted into Slytherin and Lily was sorted into Gryffindor. Their other classmates included James Potter, Sirius Black, Remus Lupin and the children of the Death Eaters Avery and Mulciber. Students in other years included Regulus Black, Lucius Malfoy and Bertha Jorkins. This was the decade of Lord Voldemort’s first rise to power, and the student body at Hogwarts reflected the turmoil of the larger world. Blood status was fair game for schoolyard taunts and many young students were fascinated by Voldemort’s power and ideas. Snape, who allegedly arrived at Hogwarts knowing more curses than most upperclassmen, was one of these students. At any rate, Lily grew more and more disturbed as her old friend Severus developed friendships with a group of Muggle-hating Slytherins, especially Avery and Mulciber.
Snape and James Potter quickly developed a loathe/loathe relationship, some of which was ordinary Slytherin – Gryffindor rivalry, and some of which was because James and his gang “The Marauders” saw Snape as an easy target. James and his best friend Sirius nicknamed Snape “Snivellus,” and taunted him about his unkempt appearance, cheered on by their friend Peter Pettigrew. As they grew older, Severus tried to hold onto his friendship for Lily Evans, but James made a “special case” out of Snape and hexed him whenever he could, usually behind Lily’s back.
Over the years. Snape spent a lot of time following James and his friends around, trying to find ways to get them expelled. Usually the Marauders had the upper hand, since they were creators of the Marauders Map, which could tell them where Snape was at any given moment. However, when Snape became too curious about where Lupin went every month, Sirius Black somehow tricked him into entering the passage under the Whomping Willow to find out. He would have been killed by Lupin as werewolf — or wound up a werewolf himself — if James Potter hadn’t realized what was happening and pulled him back. Far from being thankful, Snape felt that James was merely saving his own friend from becoming a murderer. However he promised Dumbledore to keep Lupin’s status as a werewolf a secret, and kept his promise for the next 19 years, even making the Wolfsbane Potion for Lupin when he became a teacher at Hogwarts. But after the night Remus forgot to take his potion and transformed, Snape told the Slytherins Lupin’s secret and he had to leave Hogwarts. However, by then Minister for Magic Cornelius Fudge also knew about Lupin, and the one-year-only curse on the DADA job had kicked in anyway, so Lupin could not have stayed even if Snape had said nothing.
Snape’s worst memory was of an incident that happened during his fifth year at Hogwarts. The day everyone took their Defense Against the Dark Arts O.W.L., as Severus was sitting by himself out on the Hogwarts grounds, James and Sirius snuck up on him and humiliated him in front of all the other students. Lily was nearby and stopped James, but Severus, angry and embarrassed, lashed out at Lily and called her the unforgivable — a Mudblood. He stood outside Gryffindor House all night and apologized to her, but she would have none of it, and informed Severus that he could not have Lily’s friendship and still have his Muggle-hater friends like Mulciber.
Lily severed her ties with her childhood friend and married James Potter three years later, but Snape would always love her.
As they reached majority, Snape and many of his Slytherin cohorts became Death Eaters. It is not known to what extent he participated in Voldemort’s reign of terror, although he always remained in good standing with Voldemort. While hanging around the Hog’s Head tavern, Snape eavesdropped on an interview between Albus Dumbledore and Sybill Trelawney, overhearing part of Trelawney’s prophecy regarding “the one with the power to vanquish the Dark Lord approaching … as the seven month dies.” Snape passed the incomplete Prophecy on to his master.
This small act was to be a turning point for Snape: when Snape learned that based upon the prophecy that Voldemort planned to attack the Potters to destroy James and Lily’s infant son, he was terrified. Knowing that Lily would not give up her son without a fight, Snape begged the Dark Lord to spare her life, and he agreed. But by then Snape knew better than to trust only in Voldemort. Instead, he met with Dumbledore on the Windy Hilltop to warn him of the pending attack and to ask him to keep Lily safe, then Dumbledore hired him to work as Potions Master at Hogwarts, to give him cover as a spy and a safe place to live.
The Potters were betrayed anyway by their friend Peter Pettigrew who sold them out to Voldemort, but at the time Snape and Dumbledore believed it was Sirius Black who killed the Potters and then Peter, before blowing up a street and killing Muggles. Snape was in agony that the plan had failed, and saw no reason to live, but Dumbledore convinced him to stay alive for the sake of Lily’s son, Harry, in case the Dark Lord rose again someday. Snape was so full of grief and remorse that he offered his complete allegiance to Dumbledore, on the condition that Dumbledore never reveal it to anyone, especially not Lily’s son.
When Voldemort rose again in 1995, Snape stayed undercover as a Death Eater, providing Dumbledore with inside information, and protecting Harry at the same time. This was something Snape was ideally suited for: he was such an accomplished Occlumens that even Voldemort could not see his thoughts. As Dumbledore later told Snape, “To give Voldemort what appears to be valuable information while withholding the essentials is a job I would entrust to nobody but you” . The downside for Snape was that he would be open to accusations of cowardice from both sides, something he became extremely sensitive about.
For the next 16 years Severus Snape was the Potions Master at Hogwarts and head of Slytherin House, a position of considerable authority and respect. His teaching style was based on intimidation and bullying, and yet his students routinely had good results on their O.W.L. exams. When Harry started school, Snape took an instant dislike to this child he had promised to protect. Unfortunately for Harry, he looked just like Snape’s rival James Potter — with the exception of his mother’s green eyes. Snape was also cruel to Neville Longbottom, possibly because he knew Voldemort could have gone after Neville instead and then Lily would not have died, or perhaps he could just sense that Neville was afraid of him. Harry believed that Snape favored students of his own house while actively undermining the efforts of students from Gryffindor, but that was not always true considering that Hermione Granger did well in Potions, making better grades than Draco Malfoy. When Snape became Defense Against the Dark Arts teacher, Hufflepuff Ernie MacMillan thought the class was great, and even Neville Longbottom, who had suffered in Potions, seemed to thrive in DADA.
The other professors knew that Snape had been a Death Eater, but all seemed to feel that Dumbledore’s trust was sufficient proof that Snape no longer subscribed to Voldemort’s goals.
From Harry’s point of view, Snape’s words were often at odds with his behavior. Despite petty harassment, points taken, and detentions given, Snape repeatedly protected Harry from Quirrell, stymied Umbridge’s attempt to force Harry to drink Veritaserum, and never took advantage of his innumerable chances to kill him. When Voldemort regained his powers at the end of Harry’s fourth year, Snape was able to satisfy the Dark Lord of his loyalty and reestablish his position among the Death Eaters. His role, as far as Voldemort was concerned, was to use his position at Hogwarts and his membership in the Order of the Phoenix to bring information on Harry and Dumbledore to Voldemort. Only Bellatrix, Voldemort’s most fanatical follower, harbored any doubts that Snape was a true Death Eater.
During Harry's fifth year, Snape tortured Harry in Occlumency at Dumbledore’s request, under cover of “Remedial Potions”. The lessons went badly and ended abruptly when Snape caught Harry peeking at the memories he had stored in the Pensieve for safekeeping. Harry was confused by the fact that Snape was a childhood victim of his own father’s bullying and seemed to be friends with his mother, and he felt sorry for Snape after seeing his “worst memory.” However, despite the fact that both of them glimpsed bits of each other’s deprived childhoods, neither one seems to have gained any empathy for the other. Harry certainly wasn’t the “pampered little prince” that Snape thought him, but Snape was not the “greasy git” that Sirius made him out to be either. They never talked about the memories and Harry never apologized for dipping into the Pensieve either. After fifth year, Harry insisted on blaming Snape for the death of Sirius in the Department of Mysteries. He felt that if Snape had not taunted Sirius for going to Azkaban and being locked up at Grimmauld Place, Sirius would not have left the safe house to fight only to be killed by Bellatrix Lestrange. Harry ignored the fact that Dumbledore told Sirius to stay home and safe, and his godfather chose to fight. Dumbledore, however, refused to blame Snape for the death of Sirius.
In sixth year, Harry came into the possession of Snape’s old copy of Advanced Potion Making which he had edited as a boy under the name “The Half-Blood Prince” to describe himself. Harry had no idea that Snape was the creative Prince, and wondered at times if his own father James had written the book. When Lupin told Harry that was not the case, Harry was disappointed since he thought of the Prince as a friend. Harry used the improved potion recipes to win success in N.E.W.T. level class and the favor of Potions Master Horace Slughorn, who was also a fan of his late mother Lily.
Disaster struck in the summer of 1996 when Dumbledore began hunting for Voldemort’s Horcruxes and couldn’t resist trying on the cursed Peverell ring because the Resurrection Stone was part of the setting, and Dumbledore wanted to use it to see his mother and sister again. Snape rushed to his aid, but could not permanently contain the damage. Snape estimated that Dumbledore had less than a year to live, but was shocked by the Headmaster’s response. Since Voldemort had plans to kill Dumbledore anyway (using young Draco Malfoy), Dumbledore told Snape to kill him before anyone else could, and thus spare Draco and maintain his cover. Snape saw the necessity and grimly agreed. About that time, a frantic Narcissa and a snarling Bellatrix trapped him into making an Unbreakable Vow to protect Draco and “carry out the deed that the Dark Lord … ordered Draco to perform” . Thus, Snape’s role was inescapable. It was Snape who appeared to murder Albus Dumbledore, the most powerful wizard of his age, the Headmaster who trusted him and hired him, and Harry’s last remaining father figure. However, in some ways the death was more of a mercy-killing, since Dumbledore was already “finished” by the Horcrux curse, as well as failing from Voldemort’s Cave Potion while on the Tower.
Snape escaped with Draco, but Harry was close on his heels trying to curse him and kill him. Snape kept the other Death Eaters from using the Cruciatus Curse on Harry, then admitted to him that he was the Half-Blood Prince before disapparating beyond the Hogwarts gates.
Snape had other instructions from Dumbledore, including a double cross that would hopefully protect Harry once he reached his majority and had to leave Privet Drive in the Battle of the Seven Potters. The plan worked, but ‘Mad-Eye’ Moody was killed and Snape (flying with the attacking Death Eaters), missed a shot at a Death Eater and cursed George’s ear off.
Dumbledore also instructed Snape to protect the children at Hogwarts as much as he could once Voldemort took control. Even though Snape was made Headmaster, his was no simple task because Voldemort had placed the Carrows at Hogwarts too. Alecto replaced the murdered Charity Burbage and turned Muggle Studies into a class where Muggle-haters were indoctrinated in Voldemort’s propaganda. Amycus became the Defense Against the Dark Arts professor and used it to teach the Dark Arts instead.
Once Snape was ensconced in the Headmaster's office, he could communicate with Dumbledore in a limited way via his portrait. This was how Snape knew when to get Gryffindor’s sword to Harry in the forest. Snape was told that “it must be taken under conditions of need and valor—and he must not know that you give it!” so he hid the sword in an icy pond and used his silver doe Patronus to draw Harry to its hiding place. Snape’s tenure as Headmaster ended just before the final battle when McGonagall and Flitwick confronted Snape, and rather than fight them, he escaped by flying out an open window.
Snape flew to Voldemort in the Shrieking Shack where he begged to be allowed to find Harry Potter first. Voldemort did not suspect his motives, but killed him with the help of the giant snake Nagini in an erroneous attempt to gain mastery over the Elder Wand. Snape had lost his chance to be Master of the Elder Wand when Draco arrived on the Tower first and disarmed Dumbledore before Snape arrived. Snape’s death was completely unnecessary in Voldemort’s quest for the Wand.
As he lay dying, Harry and Hermione went to Snape’s side but he was bleeding so much there was nothing they could do. Snape told Harry to take his memories as they rose from his mind, and Hermione captured them in a vial. Then Snape told Harry “Look at me,” and he died staring into the green eyes that reminded him so much of his lost love, Lily Evans. Harry took the vial to Dumbledore’s Pensieve in the Headmaster’s Office and watched the unfolding story of Snape’s childhood with Lily and Petunia, his encounters with the Marauders, and his relationship with Dumbledore. It was only after death that Harry understood Snape’s sacrifices for himself and the Order of the Phoenix, and that Snape was the “flaw in the plan” that would help him destroy Voldemort.
Severus Snape was a consummate spy and he died a perfect spy’s death: his cover intact, his final briefing delivered, remembering the woman he loved. Harry was able to use Snape’s final intelligence to kill Voldemort once and for all. In the end, Harry made sure that the wizarding world knew the true role of Severus Snape, and he named his third child Albus Severus Potter in honor of the “bravest man” he ever knew.
