Who are the World Citizens ? Numerous great men of the xxth century have advocated the institution of world sovereignty. From Winston Churchill, to Mahatma Gandhi, from LĂŠon Blum to Nobel Prize winner Willy Brandt, all have spoken in favour of the recognition of world citizenship. The impact of Solidarnosc in Poland, the mass movements across Europe which brought about the fall of the Berlin Wall and the opening in the Iron Curtain are the visible signs of the peoplesâ aspirations toward a common identity. NGOs such as WWF, Amnesty International or MSF (Doctors without Borders) shed new light upon this aspect of solidarity across the planet. Drawing the conclusion from five thousand years of world History, The Amazing Power of World Citizens pleads for the setting up of international political institutions as the only answer to the need for a harmonious social and economic development of nations.
