1969 - Northern Ireland Troubles
During 12–17 August 1969, intense political and sectarian rioting took place in Northern Ireland. There had been sporadic violence throughout the year arising out of 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.
