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.
Henry II, Holy Roman Emperor
Henry II was a member of the Ottonian dynasty of kings and emperors who ruled the Holy Roman Empire (previously Germany) from 919 to 1024. In relation to the other members of his dynasty, Henry II was the great-grandson of Henry I, great-nephew of Otto I, first-cousin once removed of Otto II, and a second-cousin to Otto III.
