The Hillsborough disaster was a fatal human crush during an association football match at Hillsborough Stadium in Sheffield, England, on 15 April 1989. It occurred during an FA Cup semi-final between Liverpool and Nottingham Forest in the two standing-only central pens in the Leppings Lane stand allocated to Liverpool supporters. Shortly before kick-off, in an attempt to ease overcrowding outside the entrance turnstiles, the police match commander David Duckenfield ordered exit gate C opened, leading to an influx of even more supporters to the pens. This led to a crowding in the pens and the crush. With 96 fatalities and 766 injuries, it remains as of 2016 the worst disaster in British sporting history.
