In 1994, the Triwizard Tournament took place at Hogwarts School of Witchcraft and Wizardry. Two schools participated along with Hogwarts: Durmstrang Institute and Beauxbatons Academy of Magic. Lord Voldemort found out through Bertha Jorkins that the Triwizard Tournament was taking place that year. He also learned that Barty Crouch Jr. was still living and under the Imperius Curse by his father. However, he broke free of it and captured Auror Alastor Moody. Once the school year began, he began to impersonate Moody and teach Defence Against the Dark Arts to the students of Hogwarts.
