Question: Dissident Irish Republican campaign includes which paramilitary group that began attacks around 2009?
Context: Óglaigh na hÉireann (ONH; ] ) is the title taken by a small dissident Irish republican paramilitary group that has taken part in the dissident Irish republican campaign.  The organisation started carrying out attacks around 2009 and was formed after a split within the Real IRA. Irish security forces is a term used to describe all security forces of the Republic of Ireland.  The term was widely used to refer to the various security operations undertaken by the Irish state during The Troubles, and still continues to be used to describe security operations aimed at undermining the ongoing dissident Irish Republican campaign. Since the Provisional Irish Republican Army (IRA) called a ceasefire and ended its armed campaign in 1997, breakaway groups opposed to the ceasefire ("dissident Irish republicans") have continued a low-level armed campaign against the British security forces in Northern Ireland.  The main paramilitaries involved are the Real IRA, Continuity IRA and Óglaigh na hÉireann.  They have targeted the British Army and Police Service of Northern Ireland (PSNI, successor of the Royal Ulster Constabulary) in gun and bomb attacks, as well as with mortars and rockets.  They have also carried out bombings that are meant to cause disruption.  However, their campaign has not been as intensive as the Provisional IRA's. The Irish National Liberation Army (INLA, Irish: "Arm Saoirse Náisiúnta na hÉireann" ) is an Irish republican socialist paramilitary group formed in December 1974, during "the Troubles".  It seeks to remove Northern Ireland from the United Kingdom and create a socialist republic encompassing all of Ireland.  It is the paramilitary wing of the Irish Republican Socialist Party (IRSP). United Ireland is the proposition that the whole of Ireland should be a single sovereign state.  At present, the island is divided politically; the sovereign state of Ireland has jurisdiction over the majority of Ireland, while Northern Ireland is part of the United Kingdom.  Achieving a united Ireland is a central tenet of Irish nationalism, particularly of both mainstream and dissident Irish republican political and paramilitary organisations.  Unionists support Northern Ireland remaining part of the United Kingdom, and therefore oppose Irish unification. This is a chronology of activities by the Continuity Irish Republican Army (CIRA), an Irish republican paramilitary group.  The group started operations in 1994, after the Provisional Irish Republican Army began a ceasefire. The Real Irish Republican Army or Real IRA (RIRA), is a dissident Irish republican paramilitary organisation which aims to bring about a united Ireland.  It formed in 1997 following a split in the Provisional IRA by dissident members, who rejected the IRA's ceasefire that year.  Like the Provisional IRA before it, the RIRA sees itself as the only rightful successor to the original Irish Republican Army and styles itself as "the Real Irish Republican Army" in English or "Óglaigh na hÉireann" in Irish.  It is an illegal organisation in the Republic of Ireland and designated as proscribed terrorist organisation in the United Kingdom and the United States. This is a timeline of actions by the Real Irish Republican Army, also called the Real IRA, an Irish republican paramilitary group.  The group was formed in late 1997 by members of the Provisional Irish Republican Army who disagreed with that organisation's ceasefire. The Provisional Irish Republican Army (Provisional IRA) was an Irish republican paramilitary organization that sought to remove Northern Ireland from the United Kingdom and to bring about an independent socialist republic encompassing all of Ireland.  It was the biggest and most active republican paramilitary group during the Troubles.  It saw itself as the successor to the original IRA and called itself simply the Irish Republican Army (IRA), or "Óglaigh na hÉireann" in Irish, and was widely referred to as such by others. The Official Irish Republican Army or Official IRA (OIRA) was an Irish republican paramilitary group whose goal was to remove Northern Ireland from the United Kingdom and create a "workers' republic" encompassing all of Ireland.  It emerged in December 1969, shortly after the beginning of the Troubles, when the Irish Republican Army split into two factions.  The other was the Provisional IRA.  Each continued to call itself simply "the IRA" and rejected the other's legitimacy.  Unlike the "Provisionals", the "Officials" were Marxist and worked to form a united front with other Irish communist groups, named the Irish National Liberation Front (NLF).  The Officials were called the NLF by the Provisionals and were sometimes nicknamed the "Red IRA" by others.
