The Irish National Liberation Army (INLA, Irish: Arm Saoirse Náisiúnta na hÉireann) is an Irish republican socialist paramilitary group formed on 8 December 1974, during the 30-year period of conflict known as "the Troubles". The group seeks to remove Northern Ireland from the United Kingdom and create a socialist republic encompassing all of Ireland. With membership estimated at 80–100 at their peak, it is the paramilitary wing of the Irish Republican Socialist Party (IRSP).
The INLA was founded by former members of the Official Irish Republican Army who opposed that group's ceasefire. It was initially known as the People's Liberation Army. The INLA waged a paramilitary campaign against the British Army and Royal Ulster Constabulary (RUC) in Northern Ireland.
