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.
King of Bavaria
With the treaty of 23 November 1870 Bavaria was integrated into the new German Empire, but permitted a relatively large degree of self-determination. The Kings of Bavaria maintained their titles, and maintained separate diplomatic and military corps. When the German Empire was abolished in November 1918 after the end of World War I, the last king of Bavaria, Ludwig III, was deposed.The title "King of Bavaria" is sometimes used in reference to Carolingian kings ruling over Bavaria. See List of rulers of Bavaria for these.
