Global leaders are expected in Belfast next month for a three-day conference to commemorate the 25th anniversary of the Good Friday Agreement.
It is being organised by Queen’s University and will be the mainstay of the official programme of events.
The names of those attending will be confirmed in the coming weeks.
Over the course of three days from Monday 17 April to Wednesday 19 April there will be a focus on the political and economic progress made since the 1998 agreement which helped deliver peace to Northern Ireland after 30 years of violence.
Young people will be given an opportunity to express their views and there’ll be a major economic summit looking at future economic opportunities.
Tanáiste Micheál Martin said the agreement had ushered in a "truly historic new beginning".
He said: "25 years on we are grateful that Queen’s University will host this important conference, to offer a moment of contemplation on the peace and on remaining challenges."
Northern Ireland Secretary Chris Heaton-Harris said the conference provided a great opportunity to reflect on the achievements of the agreement.
Mr Heaton-Harris said: "This forum will provide an opportunity for the architects of the agreement and those benefitting from Northern Ireland it helped to create, to discuss progressing peace and prosperity."
The conference has four themes, celebrating the achievements of the peacemakers, recognising the role of the women who helped deliver the agreement, listening to the views of the next generation of leaders and considering how to address future challenges for Northern Ireland.
