The Hillsborough disaster happened in April 1989 at the beginning of a FA Cup semi-final between Liverpool and Nottingham Forest, at the neutral venue of Sheffield.
Essentially, the ground was full with many fans outside, unable to get in when the game started. For whatever reason, police opened another entrance and fans surged in. At that time, grounds required Fencing to stop supporters getting onto the pitch, and in the melee 96 Liverpool fans were killed - crushed against the fences.
The aftermath of this tragedy was that fencing was abolished and all-seater stadia introduced at Premiership and Championship grounds.
