Flags of the Holy Roman Empire
In 1804, Napoleon Bonaparte declared the First French Empire. In response to this, Emperor Francis II of the Habsburg dynasty declared his personal domain to be the Austrian Empire and became Francis I of Austria. Taking the colours of the banner of the Holy Roman Emperor, the flag of the Austrian Empire was black and gold. Francis II was the last Holy Roman Emperor, with Napoleon forcing the empire's dissolution in 1806. After this point, these colours continued to be used as the flag of Austria until 1918.
Majorian
A prominent general of the Late Roman army, Majorian deposed Emperor Avitus in 457 and succeeded him. Majorian was the last emperor to make a concerted effort to restore the Western Roman Empire with its own forces. Possessing little more than Italy, Dalmatia, and some territory in northern Gaul, Majorian campaigned rigorously for three years against the Empire's enemies. His successors until the fall of the Empire, in 476/480, were actually instruments of their barbarian generals, or emperors chosen and controlled by the Eastern Roman court.
