What makes Harry explicitly the chosen one in the books is 3 things, 1) Voldemort chose him that night to be the chosen one and decided to kill him and his family personally to avoid the prophecy, 2) Harry and Neville actually talked this out and Harry chose to take the possible responsibility off of Neville and to be ...
Why was Harry Potter the chosen one instead of Neville?
It is said that the only reason Harry was the Chosen One instead of Neville is because the prophecy also said that the Dark Lord would "mark him as his equal," ultimately leaving the identity of the Chosen One in the hands of Voldemort, who chose to single out Harry over Neville to prevent the prophecy from happening.
Cuz the prophecy was not just based on date of birth, there were other conditions too which both Harry and Neville fulfilled but except that Voldy marked Harry as his equal by giving him the scar rather than Neville and so Harry became the chosen one. "The one with the power to vanquish the Dark Lord approaches...
Tension mounts, however, when Harry is mysteriously chosen by the Goblet of Fire to compete in the dangerous Triwizard Tournament, even though another Hogwarts champion, Cedric Diggory, has already been selected. Voldemort uses the Tournament for an elaborate scheme to lure Harry into a deadly trap.
Initially, Voldemort twisted Harry into the position by first looking at his lineage. Tom Riddle and Harry Potter were both half-bloods, which meant Harry was more like him than the pureblooded Neville. From there, Voldemort focused specifically on the Potters, who had defied him to no end.
Trelawney made the prophecy while interviewing for the Professor of Divination position with Dumbledore. Snape overheard the prophecy and relayed it to Voldemort who then decided it was James and Lily Potter's child.
The Prophecy states that the one with the power to vanquish the Dark Lord would be born at the end of July to parents who had defied Voldemort three times. Both Harry and Neville Longbottom fit this description, but Voldemort chose to apply the Prophecy to Harry.
Severus Snape is also a half-blood (he gave himself the nickname "The Half-Blood Prince"), as his father Tobias Snape was a Muggle. Harry himself is a half-blood, since his pure-blood father, James, married a Muggle-born witch named Lily, and his maternal grandparents were Muggles.
The prophecy foretold that the one to vanquish the dark lord would be born at the end of July, to parents who have defied Voldemort thrice. Aside from Harry, there was another boy born on the 30th of July, 1980, who satisfied this condition: Neville Longbottom.
Harry Potter was “chosen” by Lord Voldemort, but despite the life he was born into, he made the active choice to take up the title of “The Chosen One” and live with the responsibility that came along with it.
The Harry Potter movies didn't do Neville Longbottom justice for many reasons, but one narrative-defining possibility was overlooked in the movies — that Neville could have been the Chosen One, as he also fits the prophecy.
Notably, Voldemort appeared to be entirely unaware of this split, as he later created a seventh Horcrux in his quest to have six, and continued to target Harry Potter despite him now holding part of Voldemort's own soul.
He may be the titular character, but Harry is far from the most powerful wizard in the wizarding world. Sure, he does eventually go on to take down the greatest dark wizard of all time, but his success comes more as a result of his mother's sacrifice and the support of his friends than it does his own brilliance.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
The initial trauma from his childhood led to the false identity he developed in his teenage years when he decided to rewrite his story and identity. He wanted to rid the world of those who had hurt him, and he'd almost succeeded before the prophecy of Harry's birth stopped and eventually destroyed him.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
The Harry Potter prophecy suggests Neville could have been The Chosen One. Voldemort's assumption that it was Harry led to his own demise. Voldemort's choice to make Harry The Boy Who Lived was his undoing. His choices and inability to understand magic and power caused his downfall.
For the second time in Voldemort's life, the unforgivable curse rebounded on him, as the Elder Wand wouldn't kill its master. Since Harry and his friends had already destroyed all of Voldemort's Horcruxes, this finally ended Lord Voldemort's life, with Harry finally defeating the Dark Lord.
Why didn't Dumbledore tell Harry about the prophecy earlier?
Of course, there are a multitude of reasons for why Dumbledore didn't share these facts – the biggest being that, despite his incredible mind, he was fallible like the rest of us. Still, it's intriguing to wonder what might have happened had Dumbledore divulged some secrets.
Neville is a pure-blood wizard born to Frank and Alice Longbottom, who were prominent Aurors and also members of the Order of the Phoenix during the first war against Lord Voldemort.
While most fans agree that Harry is the unrefuted Chosen One, the final Deathly Hallows film (in particular) sways heavily toward highlighting a heroic Neville, revitalizing the debate regarding which boy is better suited for the iconic title. "The one with the power to vanquish the Dark Lord approaches ...
Voldemort intended Draco to die in the attempt to kill Dumbledore so that Lucius would be punished for his failure to retrieve the prophecy from the Ministry of Magic.
