Francis II, Holy Roman Emperor
Francis II (; 12 February 1768 – 2 March 1835) was the last Holy Roman Emperor, ruling from 1792 until 6 August 1806, when he dissolved the Holy Roman Empire of the German Nation after the decisive defeat at the hands of the First French Empire led by Napoleon at the Battle of Austerlitz. In 1804, he had founded the Austrian Empire and became Francis I, the first Emperor of Austria, ruling from 1804 to 1835, so later he was named the one and only "Doppelkaiser" (double emperor) in history.
For the two years between 1804 and 1806, Francis used the title and style "by the Grace of God elected Roman Emperor, ever Augustus, hereditary Emperor of Austria" and he was called the "Emperor of both the Holy Roman Empire and Austria". He was also Apostolic King of Hungary and Bohemia as Francis I. He also served as the first president of the German Confederation following its establishment in 1815.
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.
