The Irish Troubles broke out in August 1969 after the Battle of the Bogside and the Belfast August 1969 riots. Soon after the British Army was called in to restore order but events quickly shaped the conflict into a three-way urban guerrilla war with Loyalist paramilitaries like the Ulster Volunteer Force on one side, Irish Republican paramilitaries like the Provisional Irish Republican Army (IRA) on one side and the British state security services making up the other belligerent.
