 The Irish People's Liberation Organisation was a small Irish socialist republican paramilitary organisation formed in 1986 by disaffected and expelled members of the Irish National Liberation Army (INLA), whose factions coalesced in the aftermath of the supergrass trials. It developed a reputation for intra-republican and sectarian violence as well as criminality, before being forcibly disbanded by the Provisional Irish Republican Army (IRA) in 1992.
 Some of the IPLO's most notable attacks during its short existence were: 
 On 1 May 1990 the IPLO became a proscribed organisation by the British government. Although officially disbanded, the IPLO retains that classification under the Terrorism Act 2000.
 The IPLO emerged from a split within the INLA. After the 1981 Irish hunger strike, in which three of its members died, the INLA began to break apart. The INLA virtually dissolved as a coherent force in the mid-1980s. Factions associated with Belfast and Dublin fell into dispute with each other. When INLA man Harry Kirkpatrick turned supergrass, he implicated many of his former comrades in various activities and many of them were convicted on his testimony.
 Members both inside and out of prison broke away from the INLA and set up the IPLO. Some key players at the outset were Tom McAllister, Gerard Steenson, Jimmy Brown and Martin "Rook" O'Prey. Jimmy Brown formed a minor political group, known as the Republican Socialist Collective, which was to act as the political wing of the IPLO.
 The IPLO's initial priority was to forcibly disband the Irish Republican Socialist Movement from which it had split, and most of its early attacks reflected this, being more frequently against former comrades than on the security forces. The feud with the INLA lasted from 1986 to 1987 and resulted in the deaths of 12 people including IPLO leader Gerard Steenson who was shot in March 1987.
 The IPLO was accused of becoming involved in the illegal drug trade, especially in ecstasy. Some of its Belfast members were also accused of the prolonged gang rape of a North Down woman in Divis Flats in 1990. Many of its recruits had fallen out of favour with the IRA and the portents for its future were not good. Sammy Ward, a low-level IPLO member, broke away from the main body of the organisation with a few supporters when the IPLO were severely depleted and weak in Belfast. His faction attacked the rest of the IPLO, culminating in the killing of Jimmy Brown. A full-scale feud followed between two factions terming themselves "Army Council" (formerly led by Jimmy Brown) and "Belfast Brigade" (led by Ward), which led to the 3000th killing of the Troubles, Hugh McKibben, a 21-year-old "Army Council" man. Brown had been the previous victim when he was shot dead in West Belfast on 18 August 1992. This feud was described by the IPLO's critics as a lethal squabble over money and drugs.
 The Provisional IRA – by far the largest armed republican group in Ireland – decided to attack and remove the IPLO, given its involvement in the drug trade & due to increasingly provocative actions by the IPLO towards the Provisional IRA. On Saturday 31 October 1992, in an event that was later dubbed "Night of the Long Knives" by locals in Belfast, the IRA attacked the two IPLO factions in Belfast, killing the breakaway Belfast Brigade leader Sammy Ward in the Short Strand. There were also raids on pubs and clubs where IPLO members were kneecapped. On 2 November 1992 the second-in-command of the IPLO Belfast Brigade formally surrendered to the Provisional IRA Belfast Brigade adjutant, which brought an end to the group in Belfast.
 Outside Belfast the IRA did not attack any IPLO units and issued statements absolving the IPLO units in Derry, Newry and Armagh from any involvement in the drugs trade that was alleged against those in Belfast. In Dublin the IRA reprieved the IPLO Chief of Staff in return for surrendering a small cache of arms held in Ballybough.
 The IPLO also had a presence in Strabane, and in Munster; like the INLA drawing its support from the Cork, Limerick, and Shannon areas. Reportedly the group had also established small support bases in Continental Europe including France, Belgium, and the Netherlands.
 According to the Sutton database of deaths at the University of Ulster's CAIN project, the IPLO was responsible for 22 killings during the Troubles. Among its victims were twelve civilians, six INLA members, two loyalist paramilitary figures, a Royal Navy reservist, and one member of the British security forces, a Royal Ulster Constabulary constable.
