Nobel laureate, party leader, peacemaker, first minister and statesman – David Trimble had many roles. But what is the real story behind the man who made headlines and changed lives?

In this definitive biography of Trimble's life and death, award-winning journalist Stephen Walker vividly details how a shy Belfast academic changed the political landscape of Northern Ireland.

Written with the cooperation of his widow, Lady Trimble, and their grown-up children, Peacemaker offers unparalleled insights into the life of the first person to be elected first minister of Northern Ireland and the most significant unionist leader since the creation of Northern Ireland in 1921. From the beginning of his political career in the dark days of the Troubles, to bringing unionism and nationalism together to end decades of division and violence and secure peace, Trimble's personal journey mirrors the story of Northern Ireland itself.

Drawing on over 100 fresh interviews, this is a colourful and personal account of the life of a key figure in Irish history and an essential companion to Stephen Walker's bestselling biography of John Hume.
