The War’s Consequences

What were the global consequences of the First World War?

In spring 1918 the Germans launched their last major attack against France. It failed, and Germany was defeated. Austria-Hungary and the Ottoman Empire broke apart and ceased to exist. The armistice came in November, and in January 1919, as civil war spread in Russia and chaos engulfed much of eastern Europe, the victorious Western Allies came together in Paris hoping to establish a lasting peace.

Laboring intensively, the Allies soon worked out peace terms with Germany, created the peacekeeping League of Nations (see “The Paris Peace Treaties”), and reorganized eastern Europe and southwest Asia. The 1919 peace settlement, however, failed to establish a lasting peace or to resolve the issues that had brought the world to war. World War I and the treaties that ended it shaped the course of the twentieth century, often in horrible ways. Surely this was the ultimate tragedy of the Great War that cost $332 billion and left 10 million people dead and another 20 million wounded.
