Óglaigh na hÉireann (Real IRA splinter group)

Óglaigh na hÉireann (pronounced [ˈoːɡl̪ˠiː n̪ˠə ˈheːɾʲən̪ˠ]; ONH) is a small dissident Irish republican paramilitary group that took part in the dissident Irish republican campaign. The organisation started carrying out attacks around 2009 having been formed after a split, led by Seamus McGrane, within the Real IRA.

In December 2010, the group's strength was estimated to be about 50 members and it was recruiting and training in Northern Ireland and the Republic of Ireland. The group has carried out high-profile attacks on the Police Service of Northern Ireland (PSNI) and the British Army in Northern Ireland. The organisation seems to be mainly based in the Belfast area, and there are also elements within the Derry, Strabane and south Armagh / north Louth areas. However, with the growth of the larger Real IRA after it merged with other dissident groups in July 2012 to form the New IRA, the organisation's activity has steadily declined. Splits and an intelligence campaign waged against it by the PSNI and MI5 have caused the organisation to lose many members, according to media reports. The organisation is said to be aligned with the Republican Network for Unity, a republican socialist group, although RNU has denied this.

The group called a ceasefire in January 2018, announcing they were suspending all operations against the British state. However, a group of members formed the new group Irish Republican Movement and threatened to continue the fight against British forces. The ONH itself has continued to target former members and drug dealers.
