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.
Gertrude of Austria
Gertrude of Austria (also named "Gertrude of Babenberg") (1226 – 24 April 1288) was a member of the House of Babenberg, Duchess of Mödling and later titular Duchess of Austria and Styria. She was the niece of Duke Frederick II of Austria, the last male member of the Babenberg dynasty. She was, according to the Privilegium Minus the first in line to inherit the Duchies of Austria and Styria after the death of childless Frederick, but these claims were disputed by her aunt Margaret.
