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.
Duchy of Austria
The new Austrian duke took his residence at Vienna at the site of the later Hofburg Palace. He also founded Schottenstift Abbey as the Babenberg proprietary church, settled with Irish monks. The Austrian lands prospered, due to their favourable location on the Danube, as an important trade route from Krems and Mautern via Vienna down to Hungary and the Byzantine Empire. For a short time, the Babenbergs came to be one of the most influential ruling families in the Empire, peaking under the reign of Leopold V the Virtous (1177–1194) and Leopold VI the Glorious (1194–1230). In 1186, they signed the Georgenberg Pact with the first and last Otakar duke Ottokar IV of Styria and, upon his death in 1192, acquired the adjacent Styrian lands in the south, which were ruled with Austria in personal union until 1918. They also expanded their territory into the old Bavarian lands west of the Enns River, along the Traun to the city of Linz, the future capital of Upper Austria.
