The most recent example of this is known as the Troubles - a civil conflict that raged from c.1969 to the late 1990s. Belfast saw some of the worst of the Troubles in Northern Ireland, particularly in the 1970s, with rival paramilitary groups forming on both sides. Bombing, assassination and street violence formed a backdrop to life throughout the Troubles. The Provisional IRA detonated twenty-two bombs, all in a confined area in the city centre in 1972, on what is known as "Bloody Friday", killing nine people.
