The Dublin and Monaghan bombings of May 17, 1974 are a series of co-ordinated bombings in Dublin and Monaghan, Ireland. Three car bombs explode in Dublin at Parnell Street, Talbot Street and South Leinster Street during the evening rush hour and a fourth car bomb explodes in Monaghan, just south of the border with Northern Ireland, almost ninety minutes later. The bombs kill 33 civilians and a full-term unborn child, and injure almost 300. The bombings are the deadliest attack of the conflict known as the Troubles, and the deadliest attack in the Republic of Ireland‘s history. Most of the victims are young women, although the ages of the dead range from pre-born up to 80 years.

The Ulster Volunteer Force (UVF), an Ulster loyalist paramilitary group from Northern Ireland, claims responsibility for the bombings in 1993. It has launched a number of attacks in the Republic since 1969. There are allegations taken seriously by inquiries that elements of the British state security forces help the UVF carry out the bombings, including members of the Glenanne gang. Some of these allegations have come from former members of the security forces. The Irish parliament‘s Joint Committee on Justices calls the attacks an act of international terrorism involving British state forces. The month before the bombings, the British government lifts the UVF’s status as a proscribed organisation.

The bombings happen during the Ulster Workers’ Council strike. This is a general strike called by hardline loyalists and unionists in Northern Ireland who oppose the Sunningdale Agreement. Specifically, they oppose the sharing of political power with Irish nationalists and the proposed role for the Republic in the governance of Northern Ireland. The Republic’s government had helped bring about the Agreement. The strike brings down the Agreement and the Northern Ireland Assembly on May 28.

No one has ever been charged with the bombings. A campaign by the victims’ families leads to an Irish government inquiry under Justice Henry Barron. His 2003 report criticises the Garda Síochána‘s investigation and says the investigators stopped their work prematurely. It also criticises the Fine Gael/Labour Party government of the time for its inaction and lack of interest in the bombings. The report says it is likely that British security force personnel or MI5 intelligence is involved but has insufficient evidence of higher-level involvement. However, the inquiry is hindered by the British government’s refusal to release key documents. The victims’ families and others are continuing to campaign to this day for the British government to release these documents.
