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 rulers of Württemberg
The Holy Roman Empire came to an end in 1806. The Elector of Württemberg, allied to Napoleon I, anticipated its dissolution by becoming the ruler of an independent Kingdom of Württemberg in 1806.
Because of a lack of male heirs under Salic law, on the death of Wilhelm II in 1921 the royal house had to reach back to the descendants of Friedrich II Eugen (ruled 1795–97). The line of the Duke of Urach was excluded because of a morganatic marriage back in 1800 by its forebear Duke William, and so the succession devolved to the younger branch of Altshausen.
