The contemporary Pan-Orthodox conciliar process appeared in parallel to the creation in 1920 of the first global, political and multilateral institution, the League of Nations, which later became the United Nations after the Second World War. This correlation is even more apparent when we look at the well-known Encyclical of the Ecumenical Patriarchate issued in 1920, which clearly established a link between the international response to the tragedy of the Great War and the multilateral engagement of states in preventing future war and called Churches to come together and act as peace builders.
