The war between France and Germany that lasted for a period of one year from 1870-1871 was a significant war as it altered European politics. The quick defeat of Prussia and its German allies over France led to the creation of Germany as well as the assertion of the power of Germany over other countries.

The war was well planned under the leadership of the Prussian Chancellor Otto von Bismarck in such a way that it would compel the French to declare war and to gain the support of other independent German states. France was defeated, and Emperor Napoleon III was taken along with the Second French Empire, ending in the Treaty of Frankfurt. This treaty transferred the regions of Alsace and Lorraine to Germany and demanded a large sum of war damages, which virtually drained France.

It covered the supremacy of the German Empire in Europe and made Bismarck not only the uniter of Germany but the greatest statesman. Bismarck took control over politics within the German Empire after and during the war, earning the nickname ‘Iron Chancellor’. Hence, the Franco-German war undoubtedly dominated, and Germany became the mistress of Europe and placed Bismarck as the master of Germany.
