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.
The Last Legion
Orestes, who was partly of Germanic blood, was historically the "magister militum" – the senior officer of the Roman army second to the emperor. He had indeed promised his Germanic foederati a third of Italy to settle in but not to Odoacer personally. Orestes was himself a usurper, having promised the land to foederati to buy their quiescence in his rebellion against the legitimate emperor Julius Nepos. Although Orestes proclaimed his son, Romulus Augustus (derisively called "Augustulus", meaning "little Augustus") Emperor, the proclamation was not recognised as legitimate beyond the parts of the Italian Peninsula controlled by Orestes' troops. The common identification of Augustus as the "last Western Emperor" dates only from the publication of British historian Edward Gibbon's History of the Decline and Fall of the Roman Empire in the late 18th Century.
