D O C U M E N T 1 2 J U N E 1 9 2 7 6 1 12. To Count Richard Nikolaus von Coudenhove-Kalergi[1] [Berlin,] den 25. Juni 27. Sehr geehrter Herr! Sie wissen, wie sehr mir die europäische Einigungsbestrebungen am Herzen liegen,[2] am meisten aber vorläufig die Einigung der Einigungsbestrebungen! Ihrer Einladung zur aktiven Beteiligung an dem zweiten Paneuropa-Kongress[3] kann ich leider nicht Folge leisten, teils wegen Mangel an Zeit und Kraft, teils auch deshalb, weil ich etwas Originelles zu dem von Ihnen vertretenen Gegenstand nicht zu sagen habe. Ich möchte bei dieser Gelegenheit der Bitte Ausdruck geben, Sie möchten alles daran setzen, dass die beiden rivalisierenden Paneuropa-Bestrebungen zu einer ein- zigen verschmolzenen werden.[4] Dadurch würde der Sache zweifellos sehr gedient werden! In vorzüglicher Hochachtung! TLC. Nathan and Norden 2004, p. 102. [45 782]. Addressed “An die Paneuropäische Union Wien.” [1] Coudenhove-Kalergi (1894–1972) was an Austrian political author and founder of the Pan- Europa-Union, which had been established in Vienna in October 1923. [2] Einstein had cosigned an appeal initiated by the Deutscher Verband für europäische Verständi- gung in the spring of 1926. The appeal argued that in the wake of the Locarno Treaties, not only the politicians but also the people had the responsibility to foster understanding and reconciliation among the European nations (see “In Favor of European Understanding!,” Spring [after 21 March] 1926 [Vol. 15, Doc. 232]). During his trip to South America, Einstein had penned an article in which he advocated for European federalism. He claimed the war had reawakened the pan-European ideal, which was crucial to guarantee the continent’s survival (see “Pan-Europe,” 24 March and April 1925 [Vol. 14, Doc. 463]). [3] For Coudenhove-Kalergi’s invitation to the congress planned for Brussels in October 1927, see Count Richard Nikolaus von Coudenhove-Kalergi to Einstein, 21 April 1927 (Vol. 15, Abs. 829). [4] The rival organization was the Deutscher Verband für europäische Verständigung, which had emerged from the Interessengemeinschaft der europäischen Völker established in May 1924 by a group of German liberal and moderately left-wing parliamentarians. The leaders of the Verband, which was formed in the spring of 1926, were the DDP politicians Wilhelm Heile and Walther Schücking. In contrast to the Pan-Europa Union, which advocated for a united political entity in con- tinental Europe (i.e., one that would exclude Great Britain and the Soviet Union), the Verband opposed the “continental regionalization” of the League of Nations, as it feared this would lead to the League’s demise (see Holl 1974, p. 44, and Orluc 2010, pp. 151–152).
