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.
Imperial and Royal Army during the Napoleonic Wars
The Imperial and Royal or Imperial Austrian Army () was strictly speaking, the armed force of the Holy Roman Empire under its last monarch, the Habsburg Emperor Francis II, although in reality, it was nearly all composed of the Habsburg army. When the Holy Roman Empire was dissolved in 1806, it assumed its title of the Army of the Austrian Empire under the same monarch, now known as Emperor Francis I of Austria.
