The formation of the Confederation of the Rhine was not altogether a voluntary option for its future member states. Negotiations between France and the princes who had been selected by Napoleon to be members of the future alliance had been dragging on for the first six months of 1806 when Napoleon decided to rush things. On 12 July, the Paris envoys of the various princes were summoned to the ministry of Foreign Affairs to find themselves instructed by
Talleyrand to sign the treaty of the new alliance, whose terms had been decided between him and Napoleon. This caused consternation among the envoys given that the terms were far more onerous for the princes than what had been expected. They all protested that they were not empowered to sign before their masters authorized them to do so, but Talleyrand compelled them to sign then and there and so they did under duress. King
Maximilian I Joseph of Bavaria, who alone among the princes had been sent a copy of the proposed treaty, was aghast. Among other things, Bavaria would lose control of its foreign policy which would now be in the hands of Napoleon, the "
Protector of the Confederation". He hurriedly sent Baron Karl von Gravenreuth to Paris with instructions to reject a confederation which he said gave to the Protector a power "more extensive than the Emperor of Germany ever had". Von Gravenreuth was detained long enough at the French border so that when he finally arrived in Paris all the other princes had signed. He therefore found it inadvisable to deliver the King’s views on the matter. In the words of Enno E. Kraehe: "Only by such crude methods was Napoleon able at last to found the Confederation of the Rhine". On signing the Treaty of the Confederation of the Rhine (), 16 German states joined in a loose
confederation of sovereign states (the treaty called it the ''''). The "
Protector of the Confederation" was a hereditary office of the Emperor of the French, Napoleon. On 1 August, as the treaty compelled them to do, the members of the confederation formally seceded from the Holy Roman Empire, and on 6 August, following an ultimatum by Napoleon,
Francis II, who had already proclaimed himself Emperor of Austria in 1804, declared the Holy Roman Empire dissolved. According to the treaty, the confederation was to be run by common constitutional bodies, but the individual states (in particular the larger ones) wanted unlimited
sovereignty. In order to add luster to his newly-founded dynasty, the French Emperor pressed hard to arrange a marriage between his step-son
Eugène de Beauharnais and
Augusta of Bavaria. Napoleon had already contemplated marrying Beauharnais to a
Wittelsbach princess in 1804 but it was only in 1806, following his elevation to the status of king, that Max Joseph gave in to Napoleon’s pressure. Other royal marriages were arranged between
Stéphanie de Beauharnais and
Charles, Grand Duke of Baden and
Jérôme Bonaparte and
Catharina of Württemberg. After
Prussia lost to France in 1806, Napoleon cajoled most of the secondary states of Germany into the Confederation of the Rhine. Eventually, an additional 23 German states joined the Confederation. It was at its largest in 1808, when it included 36 states—four kingdoms, five grand duchies, 13
duchies, seventeen
principalities, and the Free
Hansa towns of
Hamburg,
Lübeck, and
Bremen. The west bank of the Rhine and the
Principality of Erfurt had been annexed outright by the French Empire. Thus, as either emperor of the French or protector of the Confederation of the Rhine, Napoleon was now the overlord of all of Germany except Austria,
Prussia, Danish
Holstein, and
Swedish Pomerania, plus previously independent
Switzerland, which were not included in the Confederation. In 1810 large parts of what is now northwest Germany were quickly annexed to France in order to better monitor the
trade embargo with
Great Britain, the
Continental System. The Confederation of the Rhine collapsed in 1813, in the aftermath of Napoleon's
failed invasion of Russia. Many of its members changed sides after the
Battle of Leipzig, when it became apparent Napoleon would lose the
War of the Sixth Coalition. ==Types of states within the Confederation==
