Charles I of Austria
Charles I or Karl I (Karl Franz Joseph Ludwig Hubert Georg Otto Maria; 17 August 18871 April 1922) was the last Emperor of Austria, the last King of Hungary (as Charles IV, ), the last King of Bohemia (as Charles III), and the last monarch belonging to the House of Habsburg-Lorraine. After his uncle Archduke Franz Ferdinand of Austria was assassinated in 1914, Charles became heir presumptive of Emperor Franz Josef. Charles I reigned from 1916 until 1918, when he "renounced participation" in state affairs, but did not abdicate. He spent the remaining years of his life attempting to restore the monarchy until his death in 1922. Beatified by Pope John Paul II in 2004, he is known to the Catholic Church as Blessed Karl of Austria.
Emperor of Austria
From 1806 onwards, Francis was Emperor of Austria only. He had three successors—Ferdinand I, Francis Joseph I and Charles I—before the Empire broke apart in 1918. A coronation ceremony was never established; the heir to the throne became emperor the moment his predecessor died or abdicated. The symbol of the Austrian Emperor was the dynasty's private crown dating back to Rudolf II (r. 1576–1612), (called "Rudolfinische Hauskrone" by the experts), which should convey the dignity and myth of the Habsburgs.
