Franco-Prussian War

or Franco-German War

(1870–71) War in which a coalition of German states led by Prussia defeated France, ending French hegemony in continental Europe and creating a unified Germany. The immediate cause was the candidacy of Prince Leopold of Hohenzollern-Sigmaringen for the Spanish throne, which raised the possibility of a combination of Prussia and Spain against France. Following diplomatic maneuvers to block Leopold's candidacy, the Prussian chancellor Otto von Bismarck published the Ems Telegram to provoke the French government into declaring war, which it did. The other German states sided with Prussia, and German troops under Gen. Helmuth von Moltke, superior in numbers and organization, scored repeated victories. After Napoleon III surrendered at the Battle of Sedan, French resistance was carried on by a new government, which deposed the emperor and established the Third Republic. Paris surrendered, but while treaty negotiations were going on, an insurrection by radicals in Paris created a short-lived government, the Paris Commune. After its suppression, a harsh peace treaty was implemented: Germany annexed Alsace and half of Lorraine, and France was occupied until a large indemnity was paid. The German empire was established when William I of Prussia was proclaimed German emperor in 1871. The peace was an unstable one, marked by France's determination to recover Alsace-Lorraine and Germany's mounting imperialism, led by Prussian militarism. Their mutual animosity was a driving force that led to World War I.
