Emperor
The first Austrian Emperor was the last Holy Roman Emperor Francis II. In the face of aggressions by Napoleon, Francis feared for the future of the Holy Roman Empire. He wished to maintain his and his family's Imperial status in the event that the Holy Roman Empire should be dissolved, as it indeed was in 1806 when an Austrian-led army suffered a humiliating defeat at the Battle of Austerlitz. After which, the victorious Napoleon proceeded to dismantle the old "Reich" by severing a good portion from the empire and turning it into a separate Confederation of the Rhine. With the size of his imperial realm significantly reduced, Francis II, "Holy Roman Emperor" became Francis I, "Emperor of Austria". The new imperial title may have sounded less prestigious than the old one, but Francis' dynasty continued to rule from Austria and a Habsburg monarch was still an emperor ("Kaiser"), and not just merely a king ("König"), in name.
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.
