In the 1800s, nationalist feelings were strong in the hearts of the middle-class Germans. They united in 1848 to create a nation-state out of the numerous German States. But the monarchy and the military got together to repress them and they gained support from the landowners of Prussia (the Junkers) too. Prussia soon became the leader of the German unification movement. Its Chief Minister Otto von Bismarck was the architect of the process with support from Prussian army and Prussian bureaucracy. The unification process was completed after Prussia won wars with Austria, Denmark, and France over seven years time. In January 1871, the Prussian king, William I, was proclaimed the German Emperor in a ceremony held at Versailles.
