Overview
Formed: 
January 1, 2006
Disbanded: 
January 1, 2009

Óglaigh na hÉireann (ONH1) was one of two Provisional Irish Republican Army (PIRA) splinter groups to operate separately under the same name after 2005. ONH1 was the first two emerge but the less active of the two, having effectively fallen apart by the time the other ONH, ONH2, rose to prominence in 2009. ONH1 split from the Continuity Irish Republican Army (CIRA) in 2005 or 2006 for reasons that are unclear. Like all republican paramilitary groups descended from the Irish Republican Army (IRA), it sought the withdrawal of the British from Northern Ireland and the unification of Northern and Southern Ireland. ONH1 targeted political figures and police officers, though the only murder attributed to the organization was that of a former Real Irish Republican Army (rIRA) member in 2008.
