Unification of Germany
The third niche contains a relief of Emperor William I, celebrating his victory over France in the Franco-Prussian War of 1870/71 and his role as unifier of Germany as the first Emperor of the German Empire. He is explicitly equated with Arminius in the inscription. Underneath, an inscription states that Napoleon III declared war on Prussia in July 1870, which resulted in "utter defeat" for France at the hand of the combined German states and the establishment of the Unification of Germany.
