The Royal Ulster Constabulary was the police force in Northern Ireland from 1922 to 2001. Following the awarding of the George Cross in 2000, its formal title became the Royal Ulster Constabulary, GC. It was founded on 1 June 1922 out of the Royal Irish Constabulary (RIC). At its peak the force had around 8,500 officers with a further 4,500 who were members of the RUC Reserve. During the Troubles, 319 members of the RUC were killed and almost 9,000 injured in paramilitary assassinations or attacks, mostly by the Provisional IRA, which made, by 1983, the RUC the most dangerous police force in the world in which to serve. In the same period, the RUC killed 55 people, 28 of whom were civilians.
