Duel between Albus Dumbledore and Gellert Grindelwald

The duel between Albus Dumbledore and Dark Wizard, Gellert Grindelwald took place some time before Dumbledore's ascension to the position of Headmaster of Hogwarts School of Witchcraft and Wizardry.

Background
Decades before the legendary duel, Gellert Grindelwald had come to Godric's Hollow to stay with his great aunt Bathilda Bagshot. He became friends with the seventeen year old Albus Dumbledore, and they both became obsessed with the powerful objects known as the Deathly Hallows. This trio included the Elder Wand, Resurrection Stone, and Cloak of Invisibility.

The plans became more and more far-fetched. Albus's younger brother Aberforth intervened and pointed out the impossibilities of the scheme. Gellert became quickly tempered and the three began to duel. Ariana Dumbledore was killed in the process. This caused the end of Dumbledore and Grindelwald's friendship and for Grindelwald to flee and raise an army in an attempt to continue his plan of wizarding superiority. (Chicka lang..)



The duel
As Grindelwald gained power, it was decided that Albus Dumbledore would be the only one able to stop him. Dumbledore procrastinated. He put off the encounter until it would seem that it was unacceptable to put off the confrontation any longer.

The resulting battle was one of the most well known duels in the world, and one of Dumbledore's most famous moments, with Dumbledore winning the duel and the Elder Wand's allegiance.

Aftermath
Gellert Grindelwald was captured and detained in Nurmengard, a prison that he himself had constructed to hold his enemies.

Albus Dumbledore returned to his place in Hogwarts until his death in 1997. His victory in this battle would be published on his Chocolate Frog Card.
