Yes, Harry Potter does break the Elder Wand in the book series. In the final book, ‘Harry Potter and the Deathly Hallows,’ after the defeat of Voldemort, Harry decides to take a different path than to wield the infamous wand that has caused so much suffering. He recognizes its power and the danger it poses if it falls into the wrong hands again.
In the climactic moments of the story, Harry places the Elder Wand against a large stone and gives it a powerful blow, shattering it. This act signifies Harry’s rejection of power for its own sake and his commitment to maintaining peace and protecting those he loves. By breaking the Elder Wand, he ensures that its legacy of destruction will not continue.
Furthermore, Harry intends to die a natural death, choosing to be an ordinary wizard rather than one who is tempted by the overwhelming power of the Elder Wand. This pivotal moment reinforces the overarching theme of the series that true power lies not in magic, but in love, choice, and sacrifice.
