German Confederation [SEP] Introduction
The German Confederation () was an association of 39 predominantly German-speaking sovereign states in Central Europe, created by the Congress of Vienna in 1815 as a replacement of the former Holy Roman Empire, which had been dissolved in 1806. The German Confederation did not include certain German-speaking lands in the eastern portion of the Kingdom of Prussia (East Prussia, West Prussia and Posen), the German-speaking cantons of Switzerland, and the French region of Alsace, which was predominantly German-speaking. The Confederation was weakened by rivalry between the Kingdom of Prussia and the Austrian Empire and the inability of its multiple members to compromise.
