The Continuity Irish Republican Army, styling itself as the Irish Republican Army, is an Irish republican paramilitary group that aims to bring about a united Ireland. It claims to be a direct continuation of the original Irish Republican Army and the national army of the Irish Republic that was proclaimed in 1916. It emerged from a split in the Provisional IRA in 1986 but did not become active until the Provisional IRA ceasefire of 1994. It is an illegal organisation in the Republic of Ireland and is designated a terrorist organisation in the United Kingdom, New Zealand and the United States. It has links with the political party Republican Sinn Féin (RSF).
