When Dementors are introduced to the canon, they are said to be the guards of the wizard prison Azkaban.

It would seem, comparing to regular real-world prisons, that their duties would be to a) prevent prisoners from escaping (obviously), and b) perform basic caretaking needs for prisoners, such as ensuring they have basic amenities to survive like food and water. As far as I know it is never stated that there are any other workers at Azkaban; it seems to just be the Dementors. However, every encounter with them throughout the books seems to show they are clearly incapable of these tasks.

In the third book it is stated that they cannot differentiate between people who deserve their punishment and those who don't and treat all with the same level of severity. While there are obviously many terrible people in Azkaban, surely not all of them deserve such treatment (e.g. criminals with less serious charges).

Also, if they just go around attacking everyone they find, how can they be trusted not to do the Kiss on everyone in the prison at their own discretion? It seems like there should have to be some sort of oversight from the Ministry of Magic at the very least, but as far as I know nothing of the sort is ever mentioned.

Any thoughts on the matter would be appreciated. Thanks!

    It always struck me that the prison at Azkaban was massively out of keeping with the rest of the wizarding world, basically a torture factory where the innocent and guilty alike are subject to a 24/7 regime of mental and physical degradation.

1 Answer 1


Dementors are under the control of the Ministry of Magic, at least for the duration of all seven Harry Potter books. During Harry's hearing for violating the Decree for the Restriction of Underage Wizardry in Order of the Phoenix, Dumbledore discusses this with Umbridge, and Fudge confirms Dementors are under Ministry control:

‘If it is true that the Dementors are taking orders only from the Ministry of Magic, and it is also true that two Dementors attacked Harry and his cousin a week ago, then it follows logically that somebody at the Ministry might have ordered the attacks,’ said Dumbledore politely. ‘Of course, these particular Dementors may have been outside Ministry control –’

‘There are no Dementors outside Ministry control!’ snapped Fudge, who had turned brick red.

Dumbledore inclined his head in a little bow.

‘Then undoubtedly the Ministry will be making a full inquiry into why two Dementors were so very far from Azkaban and why they attacked without authorisation.’

Order of the Phoenix - pages 134-135 - Bloomsbury - chapter eight, The Hearing

And Dumbledore reiterates this at the Sorting Feast once the students have arrived at Hogwarts for Harry's third year:

Dumbledore cleared his throat and continued. ‘As you will all be aware after their search of the Hogwarts Express, our school is presently playing host to some of the Dementors of Azkaban, who are here on Ministry of Magic business.’

Prisoner of Azkaban - page 72 - Bloomsbury - chapter five, The Dementor

It's explicitly stated in Prisoner of Azkaban that the Dementors are the guards of Azkaban -- they are not the administrators of the prison itself. Logic suggests that witches and wizards must work at Azkaban, too. And while it doesn't reference Azkaban per se, in Prisoner of Azkaban, in the chapter The Marauders Map, while in the Three Broomsticks, Fudge references a Ministry department called the "Magical Law Enforcement Patrol. Also in Prisoner of Azkaban, we learn that Fudge visited Azkaban himself, where he speaks with Sirius Black and gives Sirius his newspaper (which is how Sirius finds out Peter Pettigrew is stil alive -- he sees Peter, in the Animagus form of Ron Weasley's rat Scabbers, on the front page of the Daily Prophet):

‘Is it true he’s mad, Minister?’

‘I wish I could say that he was,’ said Fudge slowly. ‘I certainly believe his master’s defeat unhinged him for a while. The murder of Pettigrew and all those Muggles was the action of a cornered and desperate man – cruel ... pointless. Yet I met Black on my last inspection of Azkaban. You know, most of the prisoners in there sit muttering to themselves in the dark, there’s no sense in them ... but I was shocked at how normal Black seemed. He spoke quite rationally to me. It was unnerving. You’d have thought he was merely bored – asked if I’d finished with my newspaper, cool as you please, said he missed doing the crossword. Yes, I was astounded at how little effect the Dementors seemed to be having on him – and he was one of the most heavily guarded in the place, you know. Dementors outside his door, day and night.’

Prisoner of Azkaban - page 155 - Bloomsbury - chapter ten, The Marauders Map

The theme that I've come away with over the years, after numerous re-reads of canon, is that many innocent people are sentenced to Azkaban for very terrible crimes; therefore, the Ministry, going by the prisoner's crime, rather than guilt versus innocence, justifies the abominable treatment of all its prisoners. Fudge claims that wizards who commit minor crimes do not go to Azkaban:

‘Hang on,’ blurted Harry, ‘what about my punishment?’

Fudge blinked. ‘Punishment?’

‘I broke the law!’ Harry said. ‘The Decree for the Restriction of Underage Wizardry!’

‘Oh, my dear boy, we’re not going to punish you for a little thing like that!’ cried Fudge, waving his crumpet impatiently. ‘It was an accident! We don’t send people to Azkaban just for blowing up their aunts!’

But this didn’t tally at all with Harry’s past dealings with the Ministry of Magic.

‘Last year, I got an official warning just because a house-elf smashed a pudding in my uncle’s house!’ said Harry, frowning. ‘The Ministry of Magic said I’d be expelled from Hogwarts if there was any more magic there!’

Unless Harry’s eyes were deceiving him, Fudge was suddenly looking awkward.

Prisoner of Azkaban - page 38-39 - Bloomsbury - chapter three, The Knight Bus

True justice doesn't exist under Fudge's Ministry, and things only get worse under subsequent ministers, at least through the end of book seven. J.K. Rowling has said that Harry went on to work under the Ministry of Magic's Department of Magical Law Enforcement following Voldemort's defeat and death, with Kingsley Shaklebolt as Minister For Magic. She also specifically says that the Ministry ceases using Dementors as guards for Azkaban, for exactly the problems you cite in your question.

  • This is a great in-depth answer, thanks! :) I've read the books more times than I can remember, but I hadn't had an opportunity recently, so some of that had sort of slipped my mind. I think one of the main things that confused me originally was that Sirius was able to escape by transforming into a dog and tricking the dementors, but I suppose it's reasonable he could have tricked the human guards as well, or at least sneaked past. Honestly I had forgotten about the Magical Law Enforcement Patrol, their existence and implied involvement in Azkaban does make it make a lot more sense. :) Commented Mar 18, 2014 at 12:16
  • great answer as usual Slytherincess - but how does that fit in then with Dementors guarding the prison as far back as when Snape was telling Lily about them when they were children? this would have been pre-Fudge n'est pas?

    @BP_Phoenix - Mais oui! So, Fudge was Minister for Magic from 1990 to 1996; previous to Fudge, the Minister was Millicent Bagnold, who held office from 1980 to 1990. Not a lot of info on her. But in the early 80s, Barty Crouch Sr. was aggressively prosecuting dark wizards and Dementors were consistent with his measures. Earlier than that? I honestly don't know. If I find anything, I'll leave another comment or edit my answer. I do know that it wasn't until Kingsley Shaklebolt became Minister for Magic that Dementors were banned as Azkaban guards. Sorry I can't be more helpful. :) Commented Mar 28, 2014 at 2:34
