About Royal Irish Constabulary

The Royal Irish Constabulary was the police force in Ireland between 1822 and 1922, when all of the island was part of the United Kingdom. A separate civic police force, the unarmed Dublin Metropolitan Police (DMP), patrolled the capital, while the cities of Derry and Belfast, originally with their own police forces, later had special divisions within the RIC. For most of its history, the ethnic and religious makeup of the RIC broadly matched that of the Irish population, although Anglo-Irish Protestants were overrepresented among its senior officers.
