Bartemius "Barty" Crouch Senior (d. 27 May, 1995) was an influential Ministry of Magic official during the mid-to-late 20th century. He was the Head of the Department of Magical Law Enforcement during the First Wizarding War, but was demoted to the Head of the Department of International Magical Cooperation afterwards. He had a reputation for "fighting fire with fire", exhibiting the same sort of ruthlessness and brutality against criminals as some Death Eaters did against their victims.
