18 79年 10月建立的德奥同盟是在德俄关系恶化的情况下 ,德国为了维护普法战争结束后对自己有利的欧洲格局而与奥地利签订的双边条约。 1890年俾斯麦下台后 ,德皇威廉二世开始推行“世界政策” ,这一条约的本质也发生了根本变化。因此 ,把 1879年的德奥同盟说成是德国发动第一次世界大战的主要的外交工具是不确切的。 The German-Austrian alliance established in October 1979 was a bilateral treaty signed by Austria with Austria in the aftermath of the Franco-Prussian war to safeguard its own favorable European situation under the deteriorating relations between Germany and Russia. After Bismarck’s resignation in 1890, Kaiser Wilhelm II began to implement the “world policy” and the fundamental nature of the treaty has undergone fundamental changes. Therefore, it is not clear to say that the Daughan League of 1879 was the main diplomatic instrument for Germany in launching World War I.
