"Never used an Unforgivable Curse before, have you, boy? You need to mean them, Potter! You need to really want to cause pain -- to enjoy it -- righteous anger won't hurt me for long -- I'll show you how it is done, shall I? I'll give you a lesson --"
Bellatrix Lestrange taunting Harry Potter about Unforgivable Curses during the Battle of the Department of Mysteries[src]

Unforgivable Curses are the three most powerful and sinister spells known to the wizarding world, and are tools of the Dark Arts. They were first classified as "Unforgivable" in 1717. They are the Killing Curse, Avada Kedavra, the Cruciatus Curse, Crucio, and the Imperius Curse, Imperio.

Using any of these three curses on another human being, Muggle or wizard, will result in a life sentence to Azkaban, unless there is sufficient evidence that the caster did so under the influence of the Imperius Curse. Aurors were permitted to use them during the First Wizarding War, while under Lord Voldemort's regime in 1997-1998, the curses were made legal,[2] though this was presumably repealed following Voldemort's demise.

Performance[]

"Avada Kedavra's a curse that needs a powerful bit of magic behind it—you could all get your wands out and point them at me and say the words, and I doubt I'd get so much as a nosebleed."
Barty Crouch Jr., disguised as Alastor Moody, to a Defense Against the Dark Arts class[src]

Since the Unforgivable Curses are very powerful, their use requires both great willpower and great skill in order to bring about the effects. For example, Harry Potter was unable to effectively cast the Cruciatus Curse on Bellatrix Lestrange in 1996. Despite being furious with her for her murder of his godfather, he lacked the desire to cause pain for its own sake. Harry's "righteous anger" only inflicted a brief moment of pain on her.

Shortly before the Battle of Hogwarts, Harry not only successfully used the Cruciatus Curse against Amycus Carrow, he also cast the Imperius Curse against two individuals during the Gringotts heist which led to Harry, Hermione, and Ron getting in the vault. Soon after being "cruciated" by Harry, Amycus Carrow was also subject to an Imperius Curse cast by Minerva McGonagall. Perhaps due to the fact the curses were cast during a period when the ban on their use had been lifted, there is no indication of either Harry or McGonagall being punished for using them in these circumstances.

The Three Unforgivable Curses[]

Avada Kedavra - The Killing Curse[]

File:Photo 49.jpg

Bellatrix Lestrange using the Killing Curse.

Description: Causes instant death.

The incantation of Avada Kedavra causes a blinding and intense green bolt of light to shoot from the end of the caster's wand, which, on contact with the victim, results in instant death. There are no secondary effects; the victim simply "drops dead" for no biological reason. It is possible that the victim's internal organs cease function. Muggle coroners would be unable to find a cause of death in such an attack, but the Ministry of Magic recognises the signs of the curse.

The Killing Curse has no counter-curse or blocking spell, although the green bolt may be dodged or blocked with solid objects. For instance, Albus Dumbledore once transfigured a statue from the Fountain of Magical Brethren to shield Harry Potter from Voldemort's Killing Curse during the Battle of the Department of Mysteries. If the curse misses the victim and strikes an inanimate object instead, a small explosion at the point of impact results, which may start a fire of green flame.

The Killing Curse was used regularly by Lord Voldemort, possibly more than any other spell, and his Death Eaters used it as well. The spell is performed verbally as a rule; Bellatrix Lestrange killed a fox with a non-verbal spell after Apparating with Narcissa Malfoy at Spinner's End, sensing Harry's blood in his rebirth ritual in 1995.

In 1996, Fawkes sacrificed himself by swallowing a Killing Curse that Voldemort aimed at Dumbledore. Phoenixes respond to the Killing Curse the same way as they would to any other means of death: they are consumed by fire, and are reborn from the ashes.

Lord Voldemort killed many people with this curse: his father, his grandfather, his grandmother, James Potter, Lily Potter, Charity Burbage, Frank Bryce, Gellert Grindelwald, and likely many others.

Etymology[]

During an audience interview at the Edinburgh Book Festival (15 April 2004), Rowling said: "Does anyone know where avada kedavra came from? It is an ancient spell in Aramaic, and it is the original of abracadabra, which means 'let the thing be destroyed.' Originally, it was used to cure illness and the 'thing' was the illness, but I decided to make it the 'thing' as in the person standing in front of me. I take a lot of liberties with things like that. I twist them round and make them mine." Rowling's use of this name may have been influenced by the Latin cadaver.

Crucio - The Cruciatus Curse[]

Lord Voldemort using the Cruciatus Curse on Harry Potter in 1995.

Description: Inflicts excruciating pain on the recipient of the curse (tortures them)

The Cruciatus Curse, which inflicts excruciating pain upon the victim, requires the verbal incantation and the use of a wand. The effects of the curse depend upon the desires and emotions of the character - to produce the excruciating pain implied by the name, one must, according to accomplished caster Bellatrix Lestrange, desire to cause pain purely for its own sake. The extreme pain inflicted by the curse makes it uniquely suited as a form of torture, and was used regularly by the Death Eaters.

The Cruciatus is the curse which caused Alice and Frank Longbottom such suffering that they were admitted to the permanent ward at St. Mungo's Hospital for Magical Maladies and Injuries as cases of insanity. This was carried out by Barty Crouch Jr. and Bellatrix, Rodolphus and Rabastan Lestrange.

Etymology[]

Means "I torture" in Latin, originating from crux (genitive crucis), which means "torture platform or stake", or more specifically, "cross". The word excruciating is descended from the same root - crucifixion was a form of torturous execution.

Imperio - The Imperius Curse[]

Viktor Krum under the Imperius Curse.

Description: Causes the victim to perform the unquestioned bidding of the caster.

The Imperius Curse places the victim in a trance or dreamlike state, leaving him or her under the complete control of the caster. The experience is described as a "wonderful release" from any sense of responsibility. The victim is calm, from doing things they would be physically incapable of otherwise, to committing horrible crimes, and they obey any order. For example, Barty Crouch Jr., while disguised as Alastor Moody, had Neville Longbottom perform a series of astonishing flips under the Imperius Curse. It is also seen that the curse works on animals, as he also casts the Imperius Curse on a spider during class.

Death Eaters have made use of this curse; for instance, in forcing Broderick Bode and Sturgis Podmore to try to steal a prophecy from the Department of Mysteries and to place several officials under their control to facilitate their take-over of the Ministry of Magic in 1997. Many Death Eaters also claimed to be under the Imperius Curse during the First Wizarding War to avoid imprisonment in Azkaban.

Resisting the Imperius Curse is possible, but extremely difficult. Only those of a particularly strong will can achieve it. Harry Potter, Barty Crouch Sr. and Barty Crouch Jr. each learned to resist the curse after being subjected to its effects.

Etymology[]

"Imperio" is a corruption of "Impero", Latin for "I command".

Behind the scenes[]

File:Voldemort-spell-avada-kedavra-harry-potter-14771461-500-335.jpg

Voldemort casting Avada Kedavra during the Battle of Hogwarts.

  • The three curses seemed to be called "unforgivable" because they carry an automatic life sentence in Azkaban. The name may also allude to the concept of unforgivable sin (also known as "eternal sin" or "unpardonable sin") in some Christian faiths, an act that makes salvation impossible, which would be understandable given their spell effects, particularly the Killing and Cruciatus curses.
  • Harry Potter attempted to cast the Cruciatus Curse on Bellatrix Lestrange without success in Harry Potter and the Order of the Phoenix, and attempted to do the same to Severus Snape in Harry Potter and the Half-Blood Prince. In Harry Potter and the Deathly Hallows, however, he not only successfully uses this curse on Amycus Carrow shortly before the Battle of Hogwarts, but earlier in the book also uses the Imperius Curse on Travers and Bogrod during the break-in at Gringotts. There is no known incident in which Harry cast or attempted to cast the Killing Curse, even against Voldemort himself. Despite the use of the curses being said to carry an automatic life sentence in Azkaban, Harry was apparently not punished in any way for using them (although except for two times, they were legal as he cast them during the regime of Lord Voldemort, and as for the other two times, there are no known witnesses).
  • Harry Potter is the only known wizard to have resisted the effects of all three curses. He survived the Killing Curse twice, once in 1981 and once in 1998. The effect of a Cruciatus Curse placed on him by Voldemort soon after the second incident was nullifed by the fact that the wand in question refused to harm its master. Finally, Harry learned to fight back against the Imperius Curse under the tutalege of Barty Crouch Jr.
  • At the end of the Chamber of Secrets film, Lucius Malfoy appears to begin to cast the Avada Kedavra on Harry before being interrupted by a spell cast by a (recently freed) Dobby the House Elf. This isn't a very smart move, considering he's right outside of Dumbledore's office at the time.
