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.
Frederick II, Duke of Austria
As the last Babenberg duke, Frederick the Quarrelsome signifies the end of an era in the history of Austria, beginning with the enfeoffment of Margrave Leopold I in 976. With his overambitious plans, which were frequently foiled by his erratic character, he somewhat resembled his later Habsburg successor Duke Rudolf IV. According to the 18th century historian Chrysostomus Hanthaler, Frederick was the first Austrian duke utilizing the red-white-red coat of arms after his accession—an attempt to prevail against the reluctant local nobles and to stress his autonomy towards Emperor Frederick II. The triband is first documented in a seal on a deed issued on 30 November 1230, confirming the privileges of Lilienfeld Abbey. The medieval chronicler Jans der Enikel reports that the duke appeared in a red-white-red ceremonial dress at his 1232 accolade in the Vienna Schottenstift.
