5. The Good Friday Agreement (1998)
After years of bitter conflict known as the Troubles, unionist and nationalist leaders in Northern Ireland forged the Good Friday Agreement. This landmark peace pact, backed by the British and Irish governments and mediated by President Bill Clinton, brought an end to decades of violence and sectarian division. The agreement introduced power-sharing and new political frameworks, demonstrating how even entrenched enemies can move toward lasting peace. Its success has become a global model for conflict resolution and reconciliation in deeply divided societies.
