Frankfurt was a major city of the Holy Roman Empire, being the seat of imperial elections since 885 and the city for imperial coronations from 1562 (previously in Free Imperial City of Aachen) until 1792. Frankfurt was declared an Imperial Free City (Freie und Reichsstadt) in 1372, making the city an entity of Imperial immediacy, meaning immediately subordinate to the Holy Roman Emperor and not to a regional ruler or a local nobleman.
Due to its imperial significance, Frankfurt survived mediatisation in 1803. Following the collapse of the Holy Roman Empire in 1806, Frankfurt fell to the rule of Napoleon I, who granted the city to Karl Theodor Anton Maria von Dalberg; the city became known as the Principality of Frankfurt. The Catholic cleric Dalberg emancipated Catholics living with the city boundary. In 1810 Dalberg merged Frankfurt with the Principality of Aschaffenburg, the County of Wetzlar, Fulda, and Hanau to form the Grand Duchy of Frankfurt. After the defeat of Napoleon and the collapse of the Confederation of the Rhine, Frankfurt was returned to its pre-Napoleonic constitution via the Congress of Vienna of 1815 and became a sovereign city-state and a member of the German Confederation.
A grand duchy is a country or territory whose official head of state or ruler is a monarch bearing the title of grand duke or grand duchess.
Prior to the early 1800s, the only Grand duchy in Europe was located in what is now Italy: Tuscany (declared in 1569). During the 19th century there were as many as 14 grand duchies in Europe at once, some of which were revived after the Napoleonic Empire. Some of these were sovereign and nominally independent (Baden, Hesse and by Rhine, Mecklenburg-Schwerin, Mecklenburg-Strelitz, Oldenburg, Saxe-Weimar-Eisenach and Tuscany), some sovereign but held in personal union with larger realms by a monarch whose grand-dukedom was borne as a subsidiary title (Finland, Luxembourg, Transylvania), some of which were client states of a more powerful realm (Cleves and Berg), and some whose territorial boundaries were nominal and the position purely titular (Frankfurt).
The Constitution of the Kingdom of Westphalia was the oldest constitution in Germany, adopted by the Kingdom of Westphalia on November 15, 1807. It was drafted based on the French Constitution of 1804 and served as a model for the constitutions of other states in the Confederation of the Rhine, the Napoleonic union of German states (e.g. the Grand Duchy of Frankfurt). The Constitution was adopted by royal decree on December 7, 1807 and published in the law bulletin.
Karl Theodor Anton Maria von Dalberg (8 February 1744 – 10 February 1817) was a Catholic German bishop and statesman. In various capacities, he served as Archbishop of Mainz, Prince of Regensburg, Arch-Chancellor of the Holy Roman Empire, Bishop of Constance and Worms, Prince-Primate of the Confederation of the Rhine and Grand Duke of Frankfurt. Dalberg was the last Archbishop-Elector of Mainz.
