The times were severe for Armenians of Europe, and particularly of Germany, where a second Genocide seemed to be on the horizon. To counter the anti-Armenian propaganda in Germany, the Armenian community in Potsdam, Germany published an academic book on Armenian studies called Armeniertum-Arivertum, meaning Armenism-Aryanism. Three thousand copies were printed under the leadership of Artashes Abeghyan in cooperation with German Armenologists Yohannes Lepsus and Paul Rohrbakh.
Many German Orientologists like Hans Haynrikh Sheder, Yohannes Fon Lears, Karl Rot, Rev. Gerhard Klinge, and Evar Shteer, took part in this project by submitting their academic findings about the Indo-European origins of Armenians and their Aryan linguistic identity in this book.
The book was republished in 1942-1943 in Shtugart, when the Turkish propaganda reemerged in the German press. Around the same time, Armenologist Hyek Asatrian, in cooperation with Armenian military General Garegin Njdeh, published a book called Armenia-the Cradle of Aryans in Asia.
After those publications, the German Interior Ministry issued a document recognizing Armenians as an Aryan nation. Thanks to the academics and active participation of Armenian community in Germany, the threat of a genocide of Armenians in Europe vanished.
