Unification of Germany [SEP] Introduction
The Unification of Germany into the German Empire, a Prussia-dominated state with federal features, was officially proclaimed on 18 January 1871 in the Hall of Mirrors at the Palace of Versailles in France. The new state replaced the German Confederation, a loose association of sovereign states, and the highly decentralized Holy Roman Empire. Princes of the German states, excluding Austria-Hungary and its House of Habsburg-Lorraine (the dynasty that formerly ruled over the German princes during the German Confederation and Holy Roman Empire), gathered at the ceremony to proclaim William I of Prussia and the House of Hohenzollern as German Emperor, following the French capitulation in the Franco-Prussian War.
