The victims of Bloody Sunday were innocent and their names have been cleared, a relative has said.
Tony Doherty, whose father Paddy died when paratroopers opened fire, said the victims had been vindicated and the Parachute Regiment disgraced.
To loud applause outside the Guildhall in Londonderry, he addressed thousands who had gathered to hear Lord Saville's conclusions.
He said: "It can now be proclaimed to the world that the dead and the wounded of Bloody Sunday, civil rights marchers, one and all, were innocent, one and all, gunned down on their own streets by soldiers who had been given to believe that they could kill with perfect impunity."
Thousands packed the square as relatives of the dead lined up to give their reaction.
Massive pictures of the protesters were carried aloft on banners and a minute's silence was held to remember the dead. Earlier, two thumbs raised by somebody inside the Guildhall symbolised the families' delight.
Mr Doherty said: "It was the paratroopers' mission in Derry to massacre. Bloody Sunday wounded Derry very, very badly. We may hope that from today we can begin to bind those wounds. The British people need to know, the Irish people need to know, the world now knows."
Memories of the Bloody Sunday dead boomed out across Derry's Guildhall Square as bereaved relatives read out the names of their loved ones to an audience of thousands who had packed into the space in front of the city's historic walls.
As each relative in turn came to the microphone on the steps of the venue, they read out a name of one of those killed by the Paras, before shouting the word: "Innocent."
John Kelly, whose 17-year-old brother Michael was found by the report to have been shot by soldiers without justification, made an emotional address to the crowd that recalled the civil rights movement of the 1960s. "We have overcome," he declared, prompting cheers from the throng.
