فرانسيس الثاني
By 1806 Napoleon's First French Empire had annexed German lands along the Rhine River and the North Sea. Central German states formed the Confederation of the Rhine, which sided with Napoleon. Francis II, Holy Roman Emperor, then formally dissolved the Holy Roman Empire of the German Nation (6 August 1806) and instead styled himself Emperor of Austria. The War of the Fourth Coalition (180–1807) pitted German forces on both sides against each other, and Napoleon again prevailed.
