Emperor
The first Austrian Emperor was the last Holy Roman Emperor Francis II. In the face of aggressions by Napoleon, Francis feared for the future of the Holy Roman Empire. He wished to maintain his and his family's Imperial status in the event that the Holy Roman Empire should be dissolved, as it indeed was in 1806 when an Austrian-led army suffered a humiliating defeat at the Battle of Austerlitz. After which, the victorious Napoleon proceeded to dismantle the old "Reich" by severing a good portion from the empire and turning it into a separate Confederation of the Rhine. With the size of his imperial realm significantly reduced, Francis II, "Holy Roman Emperor" became Francis I, "Emperor of Austria". The new imperial title may have sounded less prestigious than the old one, but Francis' dynasty continued to rule from Austria and a Habsburg monarch was still an emperor ("Kaiser"), and not just merely a king ("König"), in name.
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.
