The spell that ultimately killed Lord Voldemort was his own Killing Curse, Avada Kedavra, which rebounded on him due to the unique circumstances of his final duel with Harry Potter.
The Killing Curse: Avada Kedavra
The Killing Curse, Avada Kedavra, is one of the three Unforgivable Curses, widely considered the most dangerous and abhorrent spell in the wizarding world. Outlawed under wizarding law, its sole purpose is to kill the victim.
Upon impact, Avada Kedavra kills its victim instantaneously and painlessly, typically marked by a blinding flash of vibrant green light. There is no known counter-curse or block for Avada Kedavra; only sacrificial protection, specific magical phenomena (like phoenix tears or a prior blood bond), or a wand's allegiance can prevent its fatal effect.
Here are the key characteristics of the Killing Curse:
- Classification: One of the three Unforgivable Curses.
- Effect: Instantaneous and painless death for the victim.
- Visuals: Usually manifests as a blinding flash of green light.
- Legality: Strictly prohibited under wizarding law, with its use warranting a life sentence in Azkaban.
- Defense: Cannot be blocked by conventional shields or counter-curses.

How Avada Kedavra Led to Voldemort's Demise
Lord Voldemort's final confrontation with Harry Potter occurred during the Battle of Hogwarts. In this epic duel, Voldemort wielded the legendary Elder Wand, a wand believed to be unconquerable. However, unknown to Voldemort, the Elder Wand's true allegiance had shifted to Harry Potter after Harry disarmed its previous master, Draco Malfoy.
During their final duel, Voldemort cast the Killing Curse, Avada Kedavra, at Harry. Simultaneously, Harry cast his signature Disarming Charm, Expelliarmus. Because the Elder Wand refused to harm its true master, Harry, Voldemort's Avada Kedavra backfired. The powerful curse rebounded from Harry's Disarming Charm, striking Voldemort himself and fulfilling the prophecy that neither could live while the other survived.
The Significance of the Reversal
Voldemort's death by his own Killing Curse, Avada Kedavra, was profoundly symbolic. It echoed the night he first tried to kill Harry as a baby, only for the curse to rebound and seemingly destroy him then as well. In both instances, the magic of love and the Elder Wand's allegiance proved more powerful than the darkest of spells, ensuring that the source of ultimate evil was vanquished by his own chosen weapon.
