Voldemort's Last Stand

A duel between Harry Potter and Lord Voldemort occured at the end of the Battle of Hogwarts on May 2, 1998.

Background
After Harry Potter witnessed the death of Severus Snape, he took the flask of Snape's memories to Albus Dumbledore's Pensieve and, by the end of the memories, Harry realised that Snape was a loyal member of the Order of the Phoenix, and he, Harry, was a Horcrux. He went on to face Lord Voldemort, who struck him with the Killing Curse, destroying his own Horcrux.

The Battle
Believing Harry to be dead, Voldemort brought the Chosen One before the Hogwartians. Angered, Neville Longbottom ran at Voldemort and decapitated Nagini with Godric Gryffindor's Sword. This began the battle, and it didn't end until the death of Bellatrix Lestrange, at which point Harry revealed himself.

The Duel
"There are no more Horcruxes. It's just you and me now Voldemort. Neither can live while the other survives, and one of us is about to leave for good."

As soon as Harry revealed himself, he and the Dark Lord began to circle each other. Harry said to Voldemort that one of them was to die in the duel. Voldemort expressed his belief that Harry would die. Harry explained to him that Albus Dumbledore's death was planned between the former Hogwarts headmaster and Snape, that way the Elder Wand's power should have died with him. Unfortunately, Draco Malfoy disarmed Dumbledore, making him the true master of the Elder Wand. Voldemort said he would just kill Draco, but then Harry added that he disarmed Malfoy, making him the true master of the Elder Wand. At the same time, Harry and Voldemort cast their spells — Harry attempting to disarm Voldemort, and Voldemort attempting to kill Harry. The Elder Wand refused to kill its master, so it flipped over, and Harry caught it. The rebounding Killing Curse hit Lord Voldemort, and he was finally destroyed once and for all.

Aftermath
After the death of Voldemort, Harry returned the Elder Wand to Dumbledore's tomb, kept the Cloak of Invisibility, and left the Resurrection Stone where he dropped it in the Forbidden Forest. After the war ended, Harry went on to become an Auror, married Ginny Weasley, and started a family.
