Francis II, Holy Roman Emperor
Francis II (; 12 February 1768 – 2 March 1835) was the last Holy Roman Emperor, ruling from 1792 until 6 August 1806, when he dissolved the Holy Roman Empire of the German Nation after the decisive defeat at the hands of the First French Empire led by Napoleon at the Battle of Austerlitz. In 1804, he had founded the Austrian Empire and became Francis I, the first Emperor of Austria, ruling from 1804 to 1835, so later he was named the one and only "Doppelkaiser" (double emperor) in history.
For the two years between 1804 and 1806, Francis used the title and style "by the Grace of God elected Roman Emperor, ever Augustus, hereditary Emperor of Austria" and he was called the "Emperor of both the Holy Roman Empire and Austria". He was also Apostolic King of Hungary and Bohemia as Francis I. He also served as the first president of the German Confederation following its establishment in 1815.
Kingdom of Saxony
Before 1806, Saxony was part of the Holy Roman Empire, a thousand-year-old entity that had become highly decentralised over the centuries. The rulers of the Electorate of Saxony of the House of Wettin had held the title of elector for several centuries. When the Holy Roman Empire was dissolved in August 1806 following the defeat of Emperor Francis II by Napoleon at the Battle of Austerlitz, the electorate was raised to the status of an independent kingdom with the support of the First French Empire, then the dominant power in Central Europe. The last elector of Saxony became King Frederick Augustus I.
