The Principality of Erfurt (German: Fürstentum Erfurt; French: Principauté d'Erfurt) was a small state in modern Thuringia, Germany, that existed from 1807 to 1814, comprising the modern city of Erfurt and the surrounding land. It was subordinate directly to Napoleon, the Emperor of the French, rather than being a part of the Confederation of the Rhine. After nearly 3 months of siege, the city fell to Prussian, Austrian and Russian forces. Having mainly been Prussian territory before the Napoleonic Wars, most of the lands were restored to Prussia by the Congress of Vienna.
