The Reappearance of the Dark Mark was one of the most notable controversies in the history of the Quidditch World Cup, occurring on 25 August, 1994 in Dartmoor, England. A riot broke out when a large group of Death Eaters stormed Mr Roberts's campsite, destroying everything in their wake, torturing Muggles and Muggle-borns alike. The Death Eaters were fought by Ministry of Magic employees. It ended when Barty Crouch Jr fired the Dark Mark into the sky causing most of the Death Eaters to Disapparate.
