The German Empire was a complex federation of 25 states, not a monolithic power.

In short: Far from the centralized European powers of its day, the German Empire functioned as a deeply federalized union. Born from the consolidation of hundreds of fragmented territories, it granted its constituent states significant autonomy over administration, justice, and finance, creating a unique political structure that persisted until 1918.

The German Empire, established in 1871, was a federation of 25 constituent states and the imperial territory of Alsace–Lorraine. This structure was the culmination of a long process of consolidation that began during the Napoleonic Wars of 1803–1815, which reduced the over 300 political entities of the Holy Roman Empire into a more manageable number. Historian Thomas Nipperdey famously described this federalism as the central fact of the Empire's existence, distinguishing it from the more centralized models found in France or England.

At the heart of this system was the Bundesrat, an upper house where state-appointed representatives held significant power. The Empire required both the Bundesrat and the popularly elected Reichstag to approve legislation. While the central government handled national matters, states retained control over schools, churches, and their own administrative bodies. This decentralization was so profound that states like Bavaria and Württemberg maintained their own postal services, railway systems, and even specific military reserve rights, such as independent administration of their armies during peacetime.

The Empire's fiscal structure further reflected this federal nature. States held a monopoly on direct taxation, while the central government relied primarily on tariffs and indirect taxes. If the Empire required additional funds, it depended on matricular contributions from the states. Although Prussia dominated the union—holding roughly two-thirds of the population and exercising effective control over the Bundesrat—the individual states remained the primary bearers of sovereignty in the eyes of the Empire's first chancellor, Otto von Bismarck.

This federal legacy was not merely a product of the 1871 unification; it was rooted in the history of the German Confederation and the North German Confederation. The system allowed for particularist concessions, known as reserve rights, which were essential in persuading southern states to join the Empire. Even as the Empire faced internal pressures for parliamentarism, its federalist framework remained intact, eventually influencing the structure of the Weimar Republic and the modern Federal Republic of Germany.
