After three decades of conflict that left 3,500 people dead, the 1998 Good Friday Agreement reached by the political protagonists in Northern Ireland found common ground for power-sharing between unionists, who want Northern Ireland to remain part of the United Kingdom, and republicans, who call for a united and independent Ireland. Today, 25 years on, Northern Ireland has become a largely peaceful society. Our corrrespondent Hervé Amoric has been meeting Belfast families from both unionist and republican backgrounds whose lives were transformed by the Agreement.
