All Ireland and United States Sister Cities Mayor’s Summit

Cities and Counties from the USA and Ireland gathered in Dublin as part of the All Ireland – US Sister Cities Mayor’s Summit in April 2016. The Summit, the first of its kind in the world, identified projects and actions that cities can take together to improve business, education and social justice.

The event was attended by some 200 US city mayors, business, education and youth leaders from many of the sixty United States cities that are twinned with Irish local authorities. The Summit marked the centenary of 1916 and also the 60th anniversary of the establishment of Sister Cities International by President Eisenhower.

As part of the Summit, a one-day conference co-hosted by San Jose California and Dublin was held in Croke Park Conference Centre on 22 April. The conference theme of Independence & Interdependence focused on celebrating the historical ties between US and Irish civic society, business, cultural and education institutions.

The conference was attended by 400 US and Irish delegates, involved in reciprocal twinning programmes, and President Michael D. Higgins made the keynote address.


2016 also marks:

  • The Centenary of the Easter Rising that took place in 1916 in Dublin, Ireland, which precipitated Irish Independence;
  • The Centenary of the World War I Battle of Sommes in 1916, which saw the participation by Irishmen, both North and South, in the Allied Cause;
  • The 60th anniversary of the establishment of the modern day Sister Cities International citizen diplomacy movement, founded in 1956 by President Eisenhower to promote world peace through people to people and community to community connections;
  • The oldest and largest global network of citizen diplomats today, with 66 community twinning relationships between All Ireland and the United States;
  • The 20th anniversary of the Good Friday Accords, which ended the 30 year period of troubles.
