The Franco-Prussian War, was a war in 1870-1871 lost by France to the German states under the leadership of Prussia. The underlying causes of the conflict were the determination of the Prussian statesman Prince Otto Edward Leopold von Bismarck to unify Germany under Prussian control and, as a step toward this goal, to eliminate French influence over Germany. On the other hand, Napoleon III, emperor of France from 1852 to 1870, sought to regain both in France and abroad the prestige lost as a result of numerous diplomatic reverses, particularly those suffered at the hands of Prussia in the Austro-Prussian War of 1866. In addition, the military strength of Prussia, as revealed in the war with Austria, constituted a threat to French dominance on the continent of Europe.
