Which country's longest continuous deployment began because of intense political and sectarian rioting in Northern Ireland?
1969 Northern Ireland riots During 12–17 August 1969, intense political and sectarian rioting took place in Northern Ireland. There had been sporadic violence throughout the year arising from the civil rights campaign, which was demanding an end to discrimination against Irish Catholics. Civil rights marches were repeatedly attacked by both Ulster Protestant loyalists and by the Royal Ulster Constabulary (RUC), a unionist and largely Protestant police force.
Law enforcement in Ireland This is a description of law enforcement in Northern Ireland and the Republic of Ireland. Before the Republic (then called the Irish Free State) left the union, one police force - the Royal Irish Constabulary - policed almost the whole island (aside from Dublin, where the Dublin Metropolitan Police were the main force, Belfast where the Belfast Borough Police were the main force and the borough of Londonderry where the Londonderry Borough Police were the main force before merging with the RIC. See List of defunct law enforcement agencies in the United Kingdom and Irish Police records and also Royal Irish Constabulary Forum for other forces in Ireland that have been disbanded.).
