The Troubles in Northern Ireland resulted in 3,600 fatalities, 50,000 people injured and billions of pounds in damage to property.
Initially the Irish and UK Governments differed in their approach to the conflict but gradually moved to a broadly similar approach.
The US Administration became an increasingly active participant and made a significant contribution to the creation of the peace process which is now in place.
Mr Donlon will speak on how this was implemented and draw on his involvement in some of the major milestones including the 1974 Sunningdale Conference and th negotiation of the 1985 Anglo-Irish Agreement.
