Harry Potter defeated Lord Voldemort in a climactic battle at the end of Harry Potter and the Deathly Hallows, the seventh and final book in J.K. Rowling's series. Here's how it happened:
The Power of Love
The key to Voldemort's downfall was love. Voldemort, who was born without love and spent his life trying to eliminate it, was ultimately undone by it. Harry, who was loved deeply by his parents, was able to survive Voldemort's attack as a baby because his mother's love acted as a shield. This love remained with Harry throughout his life, empowering him in the final battle.
The Elder Wand
The Elder Wand, one of the Deathly Hallows, was a powerful magical object that could only be truly mastered by its rightful owner. Voldemort had stolen the Elder Wand from its previous owner, Draco Malfoy, but he never truly possessed it because he did not defeat Malfoy in a duel. In the final battle, Harry disarmed Draco, making him the true master of the wand. This meant that the Elder Wand would not harm Harry, as it was bound to its owner.
The Sacrifice
In a moment of selflessness, Harry chose to sacrifice himself for his friends and the wizarding world. This act of love, combined with the Elder Wand's allegiance to him, allowed Harry to absorb Voldemort's Avada Kedavra curse and survive.
The Final Blow
When Voldemort's Killing Curse rebounded on him, the part of his soul that resided in Harry was destroyed. Voldemort, who had become dependent on this piece of his soul for his existence, was finally vanquished. His body dissolved into dust, leaving nothing but the memory of his evil reign.
The Aftermath
Harry's victory over Voldemort marked the end of the Dark Lord's reign and ushered in a new era of peace and prosperity for the wizarding world. Harry went on to live a fulfilling life, raising his family and continuing to fight for good.
