Order of the Iron Crown (Austria)
The Holy Roman Empire, ruled by the Habsburg dynasty, gave way to the Empire of Austria between 1804 and 1806. The last Holy Roman Emperor, Franz II, was proclaimed Emperor Franz I of Austria. His daughter, the Archduchess Maria Louise, was Napoleon’s second wife and Empress Consort, and the mother of Napoleon’s only legitimate son and heir, Napoleon, Duke of Reichstadt. With the collapse of Napoleon’s empire, Imperial Austria regained its traditional control of Lombardy as the Kingdom of Lombardy–Venetia.

A detailed list of the various governments that have ruled Bologna is provided by Giovanni Battista Guidicini. In 1527, the Holy See became the absolute ruler of Bologna, and was represented by a "Legatus a latere" and a Vice-Legate. On 22 February 1530, Pope Clement VII crowned the Emperor Charles V as Holy Roman Empire, the last such event in history.
