WThe Irish Republican Army of 1922–1969, an anti-Treaty sub-group of the original Irish Republican Army, fought against the Irish Free State in the Irish Civil War, and its successors up to 1969, when the IRA split again into the Provisional IRA and Official IRA. The original Irish Republican Army fought a guerrilla war against British rule in Ireland in the Irish War of Independence between 1919 and 1921. Following the signing of the Anglo-Irish Treaty on 6 December 1921, the IRA in the 26 counties that were to become the Irish Free State split between supporters and opponents of the Treaty. The anti-Treatyites, sometimes referred to by Free State forces as Irregulars, continued to use the name Irish Republican Army (IRA) or in Irish Óglaigh na hÉireann, as did the organisation in Northern Ireland which originally supported the pro-Treaty side. Óglaigh na hÉireann was also adopted as the name of the pro-Treaty National Army, and remains the official legal title of the Irish Defence Forces.
WThe border campaign was a guerrilla warfare campaign carried out by the Irish Republican Army (IRA) against targets in Northern Ireland, with the aim of overthrowing British rule there and creating a united Ireland. It was also referred to as the "resistance campaign" by some Irish republican activists. The campaign was a military failure, but for some of its members was justified as it kept the IRA engaged for another generation.
WThe Connolly Column was the name given to a group of Irish republican socialist volunteers who fought for the Second Spanish Republic in the International Brigades during the Spanish Civil War.

The name is now retroactively applied to all Irish volunteers who fought for the Spanish Republic.
