German Empire
an empire in German-speaking central Europe, created by Bismarck in 1871 after the Franco-Prussian War by the union of twenty-five German states under the Hohenzollern king of Prussia. Also called Second Reich.
Forming an alliance with Austria–Hungary, the German Empire became the greatest industrial power in Europe and engaged in colonial expansion in Africa, China, and the Far East. Tensions arising with other colonial powers led to the First World War, after which the German Empire collapsed and the Weimar Republic was created.
