One of them was the Catholic leader of the Social Democratic and Moderate Labour Party, John Hume, considered by many to be the main architect behind the peace agreement. After joining the Northern Irish civil rights movement in the late 1960s, he was convinced that nationalism was a diminishing force in the new Europe. In his view, Northern Ireland needed greater autonomy, with powers reasonably distributed among population groups: better relations should be established between Northern Ireland and the Republic of Ireland, as well as between London and Dublin. Hume devoted a great deal of energy to attracting IRA leader Gerry Adams and the British government to the negotiations. Mr. Hume played an important role in the peace talks that culminated in the Good Friday Agreement in 1998. He was widely admired for his unwavering commitment to a peaceful and democratic policy during three decades of violence in Northern Ireland. Hume, the Catholic leader of the Social Democratic and Moderate Labour Party, was seen by many as the main architect behind the peace agreement. “What an extraordinary man, peacemaker, politician, leader, civil rights activist, family man, derryman, inspiration,” Irish Foreign Minister Simon Coveney wrote on Twitter. As chairman of the traditionally dominant northern Ireland party, David Trimble has shown great political courage in advocating, in a critical phase of the process, solutions that have led to the peace agreement. As head of the Government of Northern Ireland, he took the first steps to establish the mutual trust upon which a lasting peace must be based. Hume won the Nobel Peace Prize in 1998 with David Trimble, a former member of the Ulster Unionist Party (UUP). “He has dedicated his life to peace and for that the people of Northern Ireland will never forget him,” he said.
Former US President Bill Clinton said Hume had “led his long war for peace in Northern Ireland” “From the beginning, when the riots, John urged people to stand peacefully to their goal and was constantly critical of those who did not recognise the importance of peace,” Trimble told BBC Radio Ulster on Monday. As the peace process in the province progressed in the 1990s, with several truces by the Irish Republic Army (IRA) paramilitary group, Hume set to work to involve American politicians, especially Bill Clinton. “I never thought about being a leader. I thought about helping people. John Hume, Nobel laureate and former head of the SDLP, passed away last night. We all live in the Ireland he imagined – in peace and free to decide our own destiny. Thank you, John. pic.twitter.com/0yO5KWaTv7 Trimble began his career as a law professor at Queen`s University Belfast in the 1970s, during which he began to commit to the Progressive Party of Paramilitary Vanguard Unionism. He was removed from the Northern Ireland Constitutional Convention in 1975 and joined the UUP in 1978 after the dissolution of the VPUP.
 He remained at Queen`s University until he was elected member of Parliament for the Upper Bann in 1990. In 1995, he was elected head of the UUP.  He played an important role in the negotiations that led to the Good Friday Agreement in 1998 and, along with John Hume, won the Nobel Peace Prize for his efforts this year.
