The lone survivor of a team of so-called Islamic State extremists was convicted of murder and other charges and sentenced to life in prison without parole in the 2015 bombings and shootings across Paris that killed 130 people in the deadliest peacetime attacks in French history.
Among the victims was Briton Nick Alexander, 35, of Weeley, near Colchester.
Mr Alexander died at the Bataclan concert hall, where he was selling merchandise for the band Eagles Of Death Metal.
The special court also convicted 19 other men involved in the assault following a nine-month trial.
Chief suspect Salah Abdeslam was found guilty of murder and attempted murder in relation to a terrorist enterprise.
The court found that his explosives vest malfunctioned, dismissing his argument that he ditched the vest because he decided not to follow through with his part of the attack on the night of November 13 2015.
The killings at the Bataclan concert hall, cafes and the national stadium led to intensified French military action against extremists abroad and a security crackdown at home.
Abdeslam, a 32-year-old Belgian with Moroccan roots, was given France’s most severe sentence possible.
The sentence of life without parole has only been pronounced four times in the country, for crimes related to rape and murder of minors.
Of the defendants besides Abdeslam, 18 were given various terrorism-related convictions, and one was convicted on a lesser fraud charge.
They were given punishments ranging from suspended sentences to life in prison.
Arthur Denouveaux, who survived the Bataclan massacre, appeared tired but relieved the trial was over.
“I hope to be able to put the word ‘victim’ into the past,” he said.
“When things like this happen you have no repair possible.
“That’s why you have justice,” he said, even if “justice can’t do everything.”
He added: “It puts an exclamation point at the end of it.”
During the trial, Abdeslam proclaimed his radicalism, wept, apologized to victims and pleaded with judges to forgive his “mistakes.”
For victims’ families and survivors of the attacks, the trial has been excruciating yet crucial in their quest for justice and closure.
For months, the packed main chamber and 12 overflow rooms in the 13th century Justice Palace heard the harrowing accounts by the victims, along with evidence from Abdeslam.
The other defendants are largely accused of helping with logistics or transportation.
At least one is accused of a direct role in the deadly March 2016 attacks in Brussels, which also was claimed by the so-called Islamic State group.
The trial was an opportunity for survivors and those mourning loved ones to recount the deeply personal horrors inflicted that night and to listen to details of countless acts of bravery, humanity and compassion among strangers.
Some hoped for justice, but most just wanted tell the accused directly that they have been left irreparably scarred, but not broken.
France was changed in the wake of the attacks: Authorities declared a state of emergency and armed officers now constantly patrol public spaces.
The violence sparked soul-searching among the French and Europeans, since most of the attackers were born and raised in France or Belgium.
Presiding judge Jean-Louis Peries said at the trial’s outset that it belongs to “international and national events of this century”.
Fourteen of the defendants were in court, including Abdeslam.
All but one of the six men tried in absentia are presumed killed in Syria or Iraq; the other is in prison in Turkey.
Most of the suspects were accused of helping create false identities, transporting the attackers back to Europe from Syria or providing them with money, phones, explosives or weapons.
Abdeslam was the only defendant tried on several counts of murder and kidnapping as a member of a terrorist organisation.
“Not everyone is a jihadi, but all of those you are judging accepted to take part in a terrorist group, either by conviction, cowardliness or greed,” prosecutor Nicolas Braconnay told the court in closing arguments this month.
Some defendants, including Abdeslam, said innocent civilians were targeted because of France’s policies in the Middle East and hundreds of civilian deaths in Western airstrikes in so-called Islamic State-controlled areas of Syria and Iraq.
During his evidence, former president Francois Hollande dismissed claims that his government was at fault.
The so-called Islamic State, “this pseudo-state, declared war with the weapons of war”, Mr Hollande said.
The Paris attackers did not terrorise, shoot, kill, maim and traumatise civilians because of religion, he said, adding it was “fanaticism and barbarism”.
During closing arguments, Abdeslam’s lawyer Olivia Ronen told a panel of judges that her client is the only one in the group of attackers who did not set off explosives to kill others that night.
He cannot be convicted for murder, she argued: “If a life sentence without hope for ever experiencing freedom again is pronounced, I fear we have lost a sense of proportion.”
She emphasised through the trial that she is “not providing legitimacy to the attacks” by defending her client in court.
Abdeslam apologised to the victims at his final court appearance Monday, saying his remorse and sorrow is heartfelt and sincere. Listening to victims’ accounts of “so much suffering” changed him, he said.
“I have made mistakes, it’s true, but I am not a murderer, I am not a killer,” he said.
