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.
Last Roman Emperor
Saint Remigius, bishop of Reims and apostle of the Franks, baptised Clovis I, king of the Franks on 24 December 496. This baptism, leading to the conversion of the entire Frankish people to Nicene Christianity, was a momentous success for the Catholic Church and a seminal event in European history. He had a vision and prophesied that in the distant future, the last monarch who descended from the line of the kings of France, would be revealed and reestablish the Holy Roman Empire at the end of time. This prophecy was related through Hincmar, archbishop of Reims, and Rabanus Maurus Magnentius O.S.B., archbishop of Mainz. Marie-Julie Jahenny (1850-1941), also known as the "Breton" stigmatist, prophesied that Henry V, the Count of Chambord, was the chosen King. Despite his death, one of her predictions dated 1890 declares he is yet "reserved for the great epochs", i.e. the end of time.
