I have just watched the last of the Harry Potter movies for the second time on a long flight and my brain was addled through lack of sleep. As far as I remember, three of the eight horcruxes were destroyed in that movie.
But I couldn’t make my memory add the total destroyed up to eight across the movies. So when were they all destroyed, in which movie and by whom? And does the total add up to 8?
The Horcrux hunt was a mission given to Harry Potter in June of 1997 to find all of Lord Voldemort’s remaining Horcruxes and destroy them. The mission fell to Harry Potter to complete. He was joined by Hermione Granger and Ron Weasley, and they set off in the aftermath of Bill Weasley and Fleur Delacour’s wedding.
Lord Voldemort’s had only seven Horcruxes:
Tom Riddle’s diary. -> Destroyed by Harry Potter in Harry Potter and the Chamber of Secrets
Marvolo Gaunt’s Ring. -> Destroyed by Albus Dumbledore in Harry Potter and the Half-Blood Prince
Salazar Slytherin’s Locket. -> Destroyed by Ronald Weasley in Harry Potter and the Deathly Hallows Part I with Gryffindor’s sword.
Helga Hufflepuff’s Cup. -> Destroyed by Hermione Granger in Harry Potter and the Deathly Hallows Part 2
Rowena Ravenclaw’s Diadem. -> Destroyed by Harry Potter in Harry Potter and the Deathly Hallows Part 2
Harry Potter (unknown to Voldemort until after he had “destroyed” him) -> Destroyed in Harry Potter and the Deathly Hallows Part 2
Nagini the Snake. -> Destroyed by Neville Longbottom in Harry Potter and the Deathly Hallows Part 2
Voldemort also retained part of his soul inside him.
They eventually destroyed all of the Horcruxes by 2 May 1998. The hunt ended with the death of Lord Voldemort at the hands of Harry Potter at the end of the Battle of Hogwarts and this is in Harry Potter and the Deathly Hallows Part 2
I hope harrypotter.wikia.com has plenty of well constructed resources.
According to Albus Dumbledore, Lord Voldemort created seven horcruxes. Throughout the books and movies, five out of the seven that he created had been destroyed.
Harry Potter was an accidental horcrux. According to Dumbledore seven horcrux were created before the killing of Harry Potter’s parents, so Harry would have been the 8th horcrux. The snake was a horcrux at a later time seeing how the snake never existed during the time that the first horcruxes were created.
Dumbledore said that there was one horcrux in each house of Hogwarts. The horcrux related to the house of Gryffindor was never found.
