The Battle of Hogwarts was a conflict that signified the end of the Second Wizarding War. It took place in the early hours of 2 May, 1998, within the castle and on the grounds of Hogwarts School of Witchcraft and Wizardry. When Lord Voldemort learned that Harry Potter was in the castle to locate and destroy one of his final Horcruxes, he ordered every Death Eater and creature that had pledged loyalty to him to attack the school. Dumbledore's Army communicated the need to fight to the Order of the Phoenix and their other allies, leading to a large-scale battle.

Tom Marvolo Riddle (Lord Voldemort) led his forces from the Shrieking Shack while Kingsley Shacklebolt and Minerva McGonagall led the defenders of Hogwarts. The battle ended with a decisive victory for the Order and the D.A., with many Death Eaters and Voldemort himself dead. It was the most devastating battle of the war, with casualties including Tom Marvolo Riddle and Bellatrix Lestrange, but also Remus Lupin, Nymphadora Lupin (Tonks), Severus Snape, Fred Weasley, Colin Creevey, Lavender Brown and at least fifty more who fought against Voldemort and his Death Eaters It is also assumed to be the final conflict in which the Elder Wand took part.
