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.
Ferdinand II, Holy Roman Emperor
Matthias was elected Holy Roman Emperor only months after Rudolph II died on 20 June 1612. Since Matthias and his two surviving brothers, Maximilian III and Albert VII were childless, his succession in Austria, Bohemia, Hungary and the Holy Roman Empire was uncertain. Matthias made Ferdinand the governor of Lower and Upper Austria and appointed him as his representative in Hungary, but Klesl became his most influential advisor. Klesl wanted to forge a new princely alliance in the Holy Roman Empire with the participation of both Catholic and Protestant princes. Ferdinand and Maximilian III regarded his plan dangerous and sent envoys to Rome to convince the Pope about the importance of a pure Catholic alliance. Although the Catholic League was renewed, it declared, in accordance with Klesl's proposal, the defense of the imperial constitution as its principal purpose instead of the protection of Catholicism. Philip III of Spain announced his claim to succeed Matthias in Bohemia and Hungary, emphasizing that his mother, Anna, who was Matthias' sister, had never renounced her right to the two realms. Matthias and Ferdinand discussed the issue with Zúñiga in Linz in June and July 1613, but they did not reach an agreement. Maximilian III and Albert VII who preferred Ferdinand to Philip III renounced their claims in favor of him in August 1614, but Klesl made several efforts to delay the decision.
