Abstract
In the turbulent period following the First World War the young Count Richard Coudenhove-Kalergi founded the Pan-European Union, offering a vision of peaceful, democratic unity for Europe, with no borders, a common currency, and a single passport. His political congresses in Vienna, Berlin, and Basel attracted thousands from the intelligentsia and the cultural elite, including Albert Einstein, Thomas Mann, and Sigmund Freud, who wanted a United States of Europe brought together by consent.
