The 96 Liverpool fans who died in the Hillsborough disaster were unlawfully killed, the inquest's jury has concluded.
The jurors were told they could only reach that determination if they were sure of four 'essential' matters concerning the deaths at the 1989 FA Cup semi-final.
They had to be convinced that overall match commander Chief Superintendent David Duckenfield owed a duty of care to those who died in the disaster, and that he was in breach of that duty of care.
Thirdly, they would need to be satisfied that his breach of duty caused the deaths and, fourthly, that it amounted to 'gross negligence'.
They concluded it was unlawful killing by a 7-2 majority.
The conclusion was greeted with sobbing and cheers at the hearing in Warrington.
The jury also ruled that fan behaviour did not cause or contribute to the tragedy.
And they answered yes to the question: 'Was there any error or omission in police planning or preparation which caused or contributed to the dangerous situation that developed on the day of the match?'
The Hillsborough disaster unfolded during Liverpool's cup tie against Nottingham Forest on April 15 as thousands of fans were crushed at Sheffield Wednesday's ground.
Mr Duckenfield gave the order at 2.52pm to open exit Gate C in Leppings Lane, allowing around 2,000 fans to flood into the already packed central pens behind the goal.
The jury also found that both the police and the ambulance service caused or contributed to the loss of lives in the disaster by an error or omission after the crush in the west terrace had begun to develop.
After the key conclusions were delivered, someone in court shouted 'God bless the jury'.
The jurors were given a round of applause as they left the courtroom.
Lawyers acting for relatives of the victims said the jury's conclusions had completely vindicated the bereaved families' tireless 27-year fight for justice.
The jury of six women and three men gave their decisions on an emotionally charged day for relatives of the 96, many of whom were at court for the conclusion of the longest jury proceedings in British legal history.
Last Wednesday the jury indicated to the court in Warrington that unanimous decisions had been reached on every question apart from question six - unlawful killing.
They were given a majority direction yesterday and quickly indicated they had reached a majority decision on the outstanding question.
The fresh inquests began on March 31, 2014, in a specially built courtroom in Warrington.
The 1991 accidental deaths verdicts from the original inquests were quashed following the 2012 Hillsborough Independent Panel report after a long campaign by the families of the dead.
Dozens of relatives of the victims have attended each of the more than 300 days the court has sat at Bridgewater Place on the Cheshire town's Birchwood Park business park.
At the start of the inquests, the coroner said none of the victims should be blamed for their deaths.
Emotional tributes to each of the 96 were then delivered by family members in the form of personal portraits.
The victims' families hugged each other and broke down in tears after emerging from the court.
One man shouted 'Justice' while two men held up a red scarf that also read 'Justice'.
Others made emotional phone calls to loved ones. Two women jumped up and down overcome with emotion as they embraced.
