The Irish National Liberation Army were founded in December 1974 during a meeting in the Spa Hotel, County Dublin. 

They were formed to fight for the goals of a thirty two county Irish Workers' Republic. The founding leader of the INLA was Seamus Costello. He had been active in various IRA campaigns before leaving to set up both the IRSP and INLA. He saw that the Official IRA ceasefire of the time was leading to reformism within the movement. After arguing his point of view within that organisation for some time he failed to convince the leadership of the folly of their direction. He was then expelled. The INLA, the army of Ireland's working class, was then formed to fight for National Liberation and Socialism. The INLA have been on ceasefire since September 1998 but have stayed active in defence of working class communities, particularly in Belfast interface areas where loyalist gangsters are repeatedly launching various pogroms against innocent communities.
