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.
Albert VII, Archduke of Austria
Albert VII () (13 November 1559 – 13 July 1621) was the ruling Archduke of Austria for a few months in 1619 and, jointly with his wife, Isabella Clara Eugenia, sovereign of the Habsburg Netherlands between 1598 and 1621. Prior to this, he had been a cardinal, archbishop of Toledo, viceroy of Portugal and Governor General of the Habsburg Netherlands. He succeeded his brother Matthias as reigning archduke of Lower and Upper Austria, but abdicated in favor of Ferdinand II the same year, making it the shortest (and often ignored) reign in Austrian history.
