His dad gave it to him. To elaborate on Icecreamdif's answer, he inherited it as a family heirloom dating back to Hardwin Potter, who married Iolanthe Peverell, granddaughter of the Cloak's original owner
Why Did Dumbledore Have the Cloak of Invisibility? Dumbledore came into possession of the Cloak of Invisibility after asking James Potter if he could examine its magic. He still had it when James died, so he held onto it until Harry was old enough to handle to responsibility.
Dumbledore had borrowed the cloak from the Potters to take a look, to confirm his suspicion that the cloak was one of the Deathly Hallows. However, the attack was so sudden that the cloak would not have been useful anyway. The Potters did not even have the chance to get their wand before Voldemort attacked them.
It's not certain that James had the cloak since his 1st year. We only know that he had the cloak for a significant time during his schooling years. Harry himself passed his cloak to his mischievous son when his son was 16. Perhaps James himself only got the cloak at 16 like his namesake grandson.
In the first book, Dumbledore gives Harry an invisibility cloak, which is claimed to have been passed down by his father James Potter. The cloak is accompanied by a note, which reads: 'Your father left this in my possession when he died. It is time it was returned to you. Use it well.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
At different points, Dumbledore possessed all three Deathly Hallows. He won the Elder Wand from Grindelwald, had the Invisibility Cloak in his possession when James Potter died, and wore the Resurrection Stone as it sat in Marvolo Gaunt's ring.
While in school together, Sirius once tricked Snape into almost entering the Shrieking Shack while Lupin was there, transformed into a werewolf. James realised the danger and stopped Snape, saving his life; this is the incident Dumbledore referred to at the end of the first book.
Gifted to Harry by Professor McGonagall, after joining the Gryffindor quidditch team as their newest seeker. The Nimbus 2000 was the fastest broomstick of its time, and became Harry's trustee broom, until it was later destroyed during a quidditch match.
In short, the Potter family's vast amount of gold is due to Harry's paternal ancestors being credited in the invention of several popular and crucial potions used by the wizarding world - including Pepperup Potion , Skele-Gro , and Sleekeazy's Hair Potion - and running a massively successful potions business.
All this implies that James Potter and his friends did have the tendency to bully people for fun or “just because they can”. In fact, James outright tells Lily that he's bullying Severus Snape because of the “fact that he exists, if you know what I mean”.
The only issue is with the Secret Keeper. If the keeper is trustworthy, then the ones hidden by the charm should have nothing to worry about. The Fidelius Charm failed to protect James and Lily Potter because they put their trust in the wrong person.
The Invisibility Cloak makes a great case for being the best Hallow – as the brother who chose it was able to evade death for many years, unseen, while the other two brothers had much unhappier endings. And think of how many times Harry would've been caught out without it.
Dumbledore knew Harry and Ron were under the invisibility cloak at Hagrid's hut in Harry Potter and the Chamber of Secrets, as his eyes flickered in their direction.
He has grown afraid of Harry's connection to Voldemort. Perhaps Voldemort, knowing Dumbledore's love for Harry, would possess Harry and provoke Dumbledore to kill him. So, Dumbledore attempted to avoid Harry throughout Book 5 for Harry's own good.
Additionally, in Harry Potter and the Chamber of Secrets, Professor Dumbledore looks right at Harry and Ron underneath the Invisibility Cloak while in Hagrid's hut, suggesting that Dumbledore might actually be able to see through the Invisibility Cloak.
Once again, the trio had the wrong end of the broomstick. Snape was trying to prevent the Stone from falling into the wrong hands. Unfortunately, he was a distraction from the real threat: nobody suspected Quirrell while his colleague was 'swooping around like an overgrown bat'.
“Harry didn't like to think how much gold the Firebolt would cost. He had never wanted anything as much in his whole life — but he had never lost a Quidditch match on his Nimbus Two Thousand, and what was the point in emptying his Gringotts vault for the Firebolt, when he had a very good broom already?”
Did you know? It was Crookshanks who helped Sirius gift Harry his Firebolt. Sirius tasked the cat with taking the broomstick order to the Owl Office in Harry Potter and the Prisoner of Azkaban.
He doesn't trust Snape as Dumbledore does, but he believes that he can detect any disloyalty. Moreover, Voldemort regards Snape as highly intelligent and therefore ' as a true Slytherin ' a person whose top priority is to take care of himself. To his twisted mind, selfless equals stupid.
The acclaimed author explained that Harry paid tribute to Snape because of "forgiveness and gratitude." Though Snape bullied Harry, he also saved him.
He protects Harry while pretending to be his enemy. He sacrificed his own life to protect him. It all goes back to Lily: Snape loved her, but she chose someone else, which explains his feelings toward her son. "Professor Snape, Harry." "Yes, him - Quirrell said he hates me because he hated my father.
Draco had several reasons for lying to Bellatrix, including the fact that he was never a bad person. Moreover, he no longer found working for the Dark Lord appealing and hated how Voldemort treated his family. He did not intend to harm anyone and believed Harry was the only person capable of defeating Voldemort.
"Dumbledore fell in love with Grindelwald" and was "blinded" by it. "This was Dumbledore's tragedy."
