Ancient names, long venerated, now disappeared. The holy Roman-German emperor was converted into an emperor of Austria, the electors into kings or granddukes, all of whom enjoyed unlimited sovereign power and were free from subjection to the supremacy of the emperor. Every bond of union was dissolved with the diet of the empire and with the imperial chamber. The barons and counts of the empire and the petty princes were mediatized; the princes of Hohenlohe, Oettingen, Schwarzenberg, Thurn and Taxis, the Truchsess von Waldburg, Furstenberg, Fugger, Leiningen, Lowenstein, Solms, Hesse-Homburg, Wied-Runkel, and Orange-Fulda became subject to the neighboring Rhenish confederated princes. Of the remaining six imperial free cities, Augsburg and Nuremberg fell to Bavaria; Frankfort, under the title of grandduchy, to the ancient elector of Mayence, who was again transferred thither from Ratisbon. The ancient Hanse towns, Hamburg, Lubeck and Bremen, alone retained their freedom. The Rhenish confederation now began its wretched existence. It was established on the basis of the Helvetian republic. The sixteen confederated princes were to be completely independent and to exercise sovereign power over the internal affairs of their states, like the Swiss cantons, but were, in all foreign affairs, dependent upon Napoleon as their protector.[14] The whole Rhenish confederation became a part of the French empire. The federal assembly was to sit at Frankfort, and Dalberg, the former elector of Mayence, now grandduke of Frankfort, was nominated by Napoleon, under the title of Prince Primate, president. Napoleon's uncle, and afterward his stepson, Eugene Beauharnais, were his destined successors, by which means the control was placed entirely in the hands of France. To this confederation there belonged two kings, those of Bavaria and Wurtemberg, five granddukes, those of Frankfort, Wurzburg, Baden, Darmstadt, and Berg, and ten princes, two of Nassau, two of Hohenzollern, two of Salm, besides those of Aremberg, Isenburg, Lichtenstein and Leyen. Every trace of the ancient free constitution of Germany, her provincial Estates, was studiously annihilated. The Wurtemberg Estates, with a spirit worthy of their ancient fame, alone made an energetic protest, by which they merely succeeded in saving their honor, the king, Frederick, dissolving them by force and closing their chamber.[15] An absolute, despotic form of government, similar to that existing in France under Napoleon, was established in all the confederated states. The murder of the unfortunate bookseller, Palm of Nuremberg, who was, on the 25th of August, 1806, shot by Napoleon's order, at Braunau, for nobly refusing to give up the author of a patriotic work published by him, directed against the rule of France, and entitled, "Germany in her deepest Degradation," furnished convincing proof, were any wanting, of Napoleon's supremacy.
