* The Prophecy: The prophecy foretold that only one could live while the other survives, and that the one with the power to vanquish the Dark Lord approaches.
* The Connection: Harry and Voldemort are linked by the Horcrux (piece of Voldemort's soul) residing within Harry.
* The Sacrifice: Harry chooses to sacrifice himself, understanding that Voldemort's curse would only be broken if he died.
* The Killing Curse Rebound: Voldemort's Killing Curse, meant for Harry, backfires because Harry carries a piece of Voldemort's soul. This destroys the last Horcrux, effectively killing Voldemort.
* Survival: While Harry is "dead" for a short period, he's resurrected because the part of Voldemort's soul within him is destroyed.
In essence: Voldemort is defeated by the power of love and self-sacrifice, not brute force. The Horcruxes, a testament to Voldemort's obsession with immortality, are ultimately his undoing.
