The Franco-Prussian War (1870-1871) was a conflict between the Second French Empire and the German states of the North German Confederation led by the Kingdom of Prussia. The conflict emerged from tensions caused by German unification. Prussian chancellor Otto von Bismarck planned to provoke a French attack in order to draw the southern German states. It led to the abdication of Napoleon.
