Bankrupt billionaire Sean Quinn was close to tears as more than 5,000 people came out in support in his hometown.
With the threat of jail hanging over his head, the former tycoon looked tired as he was flanked by family and friends during the rally in Ballyconnell, Co Cavan.
The businessman will be back before the High Court on Friday, where he faces a prison sentence for his role in an asset stripping plot that put up to 500m euro beyond the reach of the former Anglo Irish Bank.
His daughter Ciara told the crowd she and her siblings were the true and rightful owners of the Quinn Group companies and that her family would still be standing when the war with the Anglo ends.
She maintained they were innocent parties who will not be scape-goated by the bank, saying: "Our lives have been torn apart, as have our life's work."
Well-known GAA figures Mickey Harte, Donegal selector Rory Gallagher and Peter Quinn spoke out in support of the family at the rally, organised by the Concerned Irish Citizens group.
Mr Quinn and his wife Patricia eventually broke down as prayers and a poem were read for their jailed son, Sean Quinn junior.
The family are caught up in a legal battle with Anglo, rebranded as IBRC, over some 2.8bn euro worth of debts and have taken a counter-case again the bank over a loans deal.
Quinn, his son and nephew Peter Darragh Quinn were found guilty of breaching court orders to stop putting up to 500m euro worth of property assets beyond the reach of the bank.
Sean Jnr is appealing his imprisonment at Mountjoy's training centre, while Peter remains on the run in Northern Ireland.
