The Troubles
Cullyhanna is in South Armagh, a region that has been a stronghold of support for the Provisional Irish Republican Army, earning it the nickname "Bandit Country". The British Army nicknamed the local IRA unit the "Cullyhanna Gun Club". The village and the surrounding area were among the most dangerous areas in Northern Ireland for the British security forces.
