In World State Nicholas Hagger followed Truman, Einstein, Churchill, Eisenhower and others in calling for a democratic, partly-federal World State with sufficient authority to abolish war, enforce disarmament, combat famine, disease and poverty, and solve the world’s ?nancial and environmental problems. Its lower house, a World Parliamentary Assembly, would initially be based in the UN General Assembly and eventually replace the UN. In this companion volume he sets out a Constitution for a United Federation of the World (UF). In 14 chapters and 145 Articles he details the UF’s structure and institutions at inter-national and supranational levels, and the rights and freedoms world citizens would be guaranteed. He lists the 26 precedents and 204 existing constitutions he consulted (including the UN Charter and the US and EU constitutional documents) and the sources on which the Articles are based. This comprehensive and authoritative Constitution sets out with great clarity and concision how the whole world can be governed, and can be laid before the UN General Assembly. As a blueprint for a World State that can bring universal peace and prosperity it may come to be regarded as one of the most remarkable feats of statecraft of our time.
