Following the fall of the Holy Roman Empire, at the beginning of the 19th century, the German Confederation was formed by several of the German states. After the revolutions of 1848, the states failed to unify under one constitution, and this led the way for Prussian dominance during the next twenty years.
In 1871, the German Empire was declared, with the uniting of the North German Confederation (formed in 1866) with the Southern German states. The new German Empire was made up of former kingdoms, duchies, principalities and cities, listed below. The king of Prussia, Kaiser Wilhelm I, was the official head of the new Empire.
