The Birmingham Six were six Northern Irishmen who were each sentenced to life imprisonment in 1975 following their false convictions for the 1974 Birmingham pub bombings.
Their convictions were later ruled unfair and reversed by the Court of Appeal on 14 March 1991. The six men were later given financial compensation ranging from £840,000 to £1.2 million.

Six men were arrested: Hugh Callaghan, Patrick Joseph Hill, Gerard Hunter, Richard McIlkenny, William Power and John Walker. Five were Belfast-born, while John Walker was born in Derry.
All six had lived in Birmingham since the 1960s. All the men except for Callaghan had left the city early on the evening of 21 November from New Street Station, shortly before the explosions. They were travelling to Belfast to attend the funeral of James McDade, an IRA member whom they all knew. McDade had accidentally killed himself on 14 November when his bomb exploded early in Coventry.
Richard McIlkenny died of cancer on 21 May 2006, aged 73. He had returned to Ireland shortly after he was freed from prison and died in hospital with his family at his bedside. Hugh Callaghan died on 27 May 2023, aged 93. Patrick Hill died on 30 December 2024 in his home in Ayrshire, aged 80.
As of 2011, of the three surviving members of the Birmingham Six, Gerard Hunter lived in Portugal; John Walker in Donegal; William Power in London.
On 12 May 1975, the six men were charged with murder. Three other men, James Kelly, Mick Murray and Michael Sheehan, were charged with conspiracy.
The trial began on 9 June 1975 at the Crown Court sitting at Lancaster Castle.
Forensic scientist Frank Skuse used positive Griess test results to claim that Hill and Power had been in charge of explosives. Callaghan, Hunter, McIlkenny and Walker all had tested negative.
The jury found the six men guilty of murder. On 15 August 1975, they were each sentenced to 21 life sentences.
