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.
Kingdom of Arles
In 1365, Charles was the last emperor to be crowned King of Arles. In 1378, Charles appointed the Dauphin of France (later King Charles VI of France) as permanent Imperial vicar to administer nominally on behalf of the Empire what remained of Arelat, and from then on Arelat in effect ceased to exist. However, the title "King of Arles" remained one of the Holy Roman Emperor's subsidiary titles until the dissolution of the Empire in 1806, and the office of the Archbishop of Trier continued to act as an archchancellor and prince-elector for the King of the Romans (the designated future Holy Roman Emperor), a status that was confirmed by the Golden Bull of 1356.
