Holy Roman Empire
The empire was dissolved on 6 August 1806, when the last Holy Roman Emperor Francis II (from 1804, Emperor Francis I of Austria) abdicated, following a military defeat by the French under Napoleon at Austerlitz (see Treaty of Pressburg). Napoleon reorganized much of the Empire into the Confederation of the Rhine, a French satellite. Francis' House of Habsburg-Lorraine survived the demise of the empire, continuing to reign as Emperors of Austria and Kings of Hungary until the Habsburg empire's final dissolution in 1918 in the aftermath of World War I.
Coronations in Europe
Since Charlemagne in 800, Holy Roman Emperors were crowned by the pope until 1530, when Charles V became the last Holy Roman Emperor to be crowned by the Pope, at Bologna. Thereafter, until the abolition of the empire in 1806, Imperial coronations were held in Frankfurt and were performed by the Spiritual Princes-Electors,the Archbishops of Cologne, Mainz and Trier. Later rulers simply proclaimed themselves "Electus Romanorum Imperator" or "Elected Emperor of the Romans", without the formality of a coronation by the Pontiff.
