Charles I or Karl Of Austria-
Charles I or Karl I (Karl Franz Joseph Ludwig Hubert Georg Otto Maria; 17 August 1887 – 1 April 1922) was the last Emperor of Austria, the last King of Hungary (as Charles IV, Hungarian: IV. Károly),[1] the last King of Croatia, last King of Bohemia (as Charles III, Czech: Karel III.), and the last monarch belonging to the House of Habsburg-Lorraine before the dissolution of Austria-Hungary. The son of Archduke Otto of Austria and Princess Maria Josepha of Saxony, Charles became heir presumptive of Emperor Franz Joseph after his uncle Archduke Franz Ferdinand of Austria was assassinated in 1914. In 1911, he married Princess Zita of Bourbon-Parma.
Charles succeeded to the thrones in November 1916 following the death of Franz Joseph. He made secret attempts to negotiate Austria-Hungary's exit from the First World War but was unsuccessful. Despite Charles' efforts to preserve the empire by transforming it into a federal union, Austria-Hungary hurtled towards disintegration: Czechoslovakia and the State of Slovenes, Croats and Serbs were proclaimed, and Hungary broke monarchic ties to Austria by the end of October 1918. Following the Armistice of 11 November 1918, Charles "renounced participation" in state affairs, but did not abdicate. The Republic of German-Austria was proclaimed the following day, and in April 1919 he was formally dethroned by the Austrian Parliament and exiled to Switzerland.
Charles spent the remaining years of his life attempting to restore the monarchy. He made two attempts to reclaim the Hungarian throne in 1921; both failed due to a lack of support from Hungary's regent Miklós Horthy. Charles was exiled for a second time to the Portuguese island of Madeira, where he soon fell ill and died of respiratory failure in 1922.
Beatified by Pope John Paul II in 2004, Charles is known to the Catholic Church as Blessed Karl of Austria.[2]

Zita of Bourbon-Parma-
Zita of Bourbon-Parma (Zita Maria delle Grazie Adelgonda Micaela Raffaela Gabriella Giuseppina Antonia Luisa Agnese; 9 May 1892 – 14 March 1989) was the wife of Charles, the last monarch of Austria-Hungary. As such, she was the last Empress of Austria and Queen of Hungary, in addition to other titles.
Born as the seventeenth child of the dispossessed Robert I, Duke of Parma, and his second wife, Infanta Maria Antonia of Portugal, Zita married the then Archduke Charles of Austria in 1911. Charles became heir presumptive to the Emperor Franz Joseph I of Austria in 1914 after the assassination of his uncle Archduke Franz Ferdinand of Austria, and acceded to the throne in 1916 after the old emperor's death.
After the end of World War I in 1918, the Habsburgs were deposed and the former empire became home to the states of Austria, Hungary, and Czechoslovakia whilst other parts were annexed to or joined the Kingdom of the Serbs, Croats and Slovenes, Italy, Romania and a reconstituted independent Poland. Charles and Zita left for exile in Switzerland and after the failure of attempts to restore royal rule in Hungary, were subsequently removed from that country by the Allies to Madeira, where Charles died in 1922. After her husband's death, Zita and her son Otto served as symbols of unity for the exiled dynasty. A devout Catholic, she raised a large family after being widowed at the age of 29, and never remarried.
