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.
God Save the Queen
Joseph Haydn was impressed by the use of "God Save the King" as a national anthem during his visit to London in 1794, and on his return to Austria composed "Gott erhalte Franz den Kaiser" ("God Save Emperor Francis") for the birthday of the last Holy Roman Emperor and Roman-German King, Francis II. It became the anthem of the Austrian Empire after the end of the Holy Roman Empire with revised lyrics, its tune ultimately being used for the German national anthem. The tune of "God Save the King" was adopted for the Prussian royal anthem "Heil Dir im Siegerkranz".
