World Federalist Movement
"One World" inspired the One World movement and the World Federalist Movement — which included among its supporters Albert Einstein, Mahatma Gandhi, Jawaharlal Nehru —and advocated strong and democratic super-national institutions. That wave of thinking foretold the postwar international order, including the United Nations System, but was also very critical of the postwar order and the UN, claiming it is insufficient to avoid another world war.
