Holy Roman Empire
The empire was dissolved on 6 August 1806, when the last Holy Roman Emperor Francis II (from 1804, Emperor Francis I of Austria) abdicated, following a military defeat by the French under Napoleon at Austerlitz (see Treaty of Pressburg). Napoleon reorganized much of the Empire into the Confederation of the Rhine, a French satellite. Francis' House of Habsburg-Lorraine survived the demise of the empire, continuing to reign as Emperors of Austria and Kings of Hungary until the Habsburg empire's final dissolution in 1918 in the aftermath of World War I.
Romulus Augustulus
As the last Western Roman emperor before the traditionally agreed-upon end of the Western Roman Empire, Romulus has been portrayed several times in film and literature; the play "Romulus the Great" (1950), by Friedrich Dürrenmatt, focuses on the reign of "Romulus Augustus" and the end of the Roman Empire in the West. The 2007 film "The Last Legion", and the novel on which it is based, includes a heavily fictionalized account of the reign and subsequent life of "Romulus Augustus"; escaping captivity with the aid of a small band of loyal Romans, he reaches Britain, where he eventually becomes Uther Pendragon.
