David Trimble was one of the most influential figures in modern British and Irish history. A Nobel Laureate, he negotiated the Good Friday Agreement in 1998 that helped to secure peace in Northern Ireland. In this first biography to chart Trimble's life and death, award-winning journalist Stephen Walker vividly details how this shy Belfast academic changed the political landscape of Northern Ireland. With the cooperation of the Trimble family, Peacemaker offers unparalleled insights into the life of a history maker: the first person to be elected First Minister of Northern Ireland and the last Ulster unionist to hold that title. Using interviews with his widow Lady Trimble and their grown-up children, the book colourfully charts Trimble's story from the County Down city of Bangor, through the divisive world of unionist politics, to his crowning moment at the Nobel Peace Prize ceremony in Oslo. It is a tale of how the leaders of unionism and nationalism worked together to end decades of violence to compromise and share power.
