The Northern Ireland's Troubles have long been a bone of contention among the Irish society. The Bloody Sunday of January 30, 1972 in Ireland was one of the conflict that occurred during the Northern Ireland's Troubles where a group of Catholic civil rights protesters were killed in an open fire by the British paratroopers. This event shocked the whole world and received massive condemnation from every part of the world. After the incident, there was a strong call for securing peace in Ireland. Both the unionist and the nationalist community south to end the conflict and various peace talks were initiated to bring ceasefire.
