The German Empire (, officially ') was the German nation state that existed from the Unification of Germany in 1871 until the abdication of Kaiser Wilhelm II in 1918. 

It was founded in 1871 when Wilhelm I, King of Prussia from the Hohenzollern dynasty was proclaimed the German Emperor in the Hall of Mirrors at the Palace of Versailles. Berlin became its capital with the Berlin Palace being the Emperor's official residence. Its constitution entered into force, and Otto von Bismarck became the first Chancellor. As these events occurred, the Prussian-led North German Confederation and its southern German allies were still engaged in the Franco-Prussian War. The state was founded with a notable exclusion of Austria and, as such, represented the Lesser German solution ("Kleindeutsche Lösung"). 

The German Empire consisted of 26 constituent territories, with most being ruled by royal families. This included four kingdoms, six grand duchies, five duchies (six before 1876), seven principalities, three free Hanseatic cities, and one imperial territory. Although Prussia became one of several kingdoms in the new realm, it contained most of its population and territory, thus remaining a powerhouse with a major say in imperial affairs. Its influence also helped define modern German culture.
