With the fall of Austria, which now left him a citizen of Czechoslovakia, and the end of World War 1, politics began to intrigue Coudenhove-Kalergi. The League of Nations, in 1918, started out as a glimmer of hope for Coudenhove-Kalergi; that the League would secure a more peaceful environment in which nations would strive for co-operation and peace (Wilson & van der Dussen, 1995). The League and Europe both disappointed him not shortly thereafter: reality at the time didn’t correspond with the idealistic intentions of the League and he felt that the League also abandoned its ideals (Thorpe, 2018). Therefore, Coudenhove-Kalergi decided that the only possible thing to do going forward was to create his own solution, a Europe that was politically united and where the abandoned ideals of the League would be fulfilled (Wiedemer, 1993).
The idea to Coudenhove-Kalergi was that it would be complementary to the Pan-American Union and a legitimate global reformation of the League (Thorpe, 2018).
