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.
List of Imperial Diet participants (1792)
The Holy Roman Empire was a highly decentralized state for most of its history, composed of hundreds of smaller states, most of which operated with some degree of independent sovereignty. Although in the earlier part of the Middle Ages, under the Salian and Hohenstaufen emperors, it was relatively centralized, as time went on the Emperor lost more and more power to the Princes. The membership of the Imperial Diet in 1792, late in the Empire's history but before the beginning of the French Revolutionary Wars, gives some insight as to the composition of the Holy Roman Empire at that time.
