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.
Margraviate of Austria
Margravial Austria reached its greatest height under Leopold III, a great friend of the church and founder of abbeys. He patronised towns and developed a great level of territorial independence. In 1139, Leopold IV inherited Bavaria. When his successor, the last margrave, Henry Jasomirgott, was deprived of Bavaria in 1156, Austria was elevated to a duchy independent from Bavaria by the of Emperor Frederick Barbarossa. From 1192 the House of Babenberg also ruled over the neighbouring Duchy of Styria. The line became extinct with the death of Duke Frederick II of Austria at the 1246 Battle of the Leitha River. The heritage was finally asserted by the German king Rudolph of Habsburg against King Ottokar II of Bohemia in the 1278 Battle on the Marchfeld.
