In Berlin on November 10 and 11, 1915, the German Chancellor, Bethmann-Hollweg, raised with the visiting Austro-Hungarian foreign minister, Baron Burián, the subject of strengthening the diplomatic alliance between their governments during the current world conflict. In order to make this alliance “a permanent factor of international politics vis-á-vis our foes,” Bethmann-Hollweg suggested “an extension of the contractual obligations in political, economic and military respects.…” Speaking from a political standpoint, he noted that the treaty of 1879 between Germany and Austria-Hungary “was based on … the idea of the predominance of the Magyars in Hungary and the Germans in Austria.” Since then the Magyars had maintained their position, but the “influence of the Germans in the other half of the empire has been continuously reduced.” Therefore, the chancellor explained, “in connection with the extension and strengthening of the alliance, it is a matter of life or death for Germany that the German element regains its old deserved position and that a stop be put to any further Slavicization.” Bethmann-Hollweg went on to tell Burián about Germany's plans for a thirty year customs alliance based on preferential tariffs, which would be lower than those granted to other lands in most-favored-nation agreements. He expected that these internal duties would be reduced every ten years, and that other European states would join this commercial league. This meeting led to a series of official negotiations about a more comprehensive treaty of alliance, which were still in process when the Central Powers collapsed late in 1918.
