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.
Last of the Romans
The term Last of the Romans ("Ultimus Romanorum") has historically been used to describe a man thought to embody the values of Ancient Roman civilization—values which, by implication, became extinct on his death. It has been used to describe a number of individuals. The first recorded instance was Julius Caesar's description of Marcus Junius Brutus the Younger as the one with whom the old Roman spirit would become extinct.In the United States, "last of the Romans" was used on numerous occasions during the early 19th century as an epithet for the political leaders and statesmen who participated in the American Revolution by signing the United States Declaration of Independence, taking part in the American Revolutionary War, or established the United States Constitution.
