Charles I and IV (, ; 17 August 1887 – 1 April 1922) was Emperor of Austria (as Charles I), King of Hungary (as Charles IV), and the ruler of the other states of the Habsburg monarchy from November 1916 until the monarchy was abolished in November 1918. He was the last of the monarchs belonging to the House of Habsburg-Lorraine to rule over Austria-Hungary. The son of Archduke Otto of Austria and Princess Maria Josepha of Saxony, Charles became heir presumptive of Emperor Franz Joseph when 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 his grand-uncle, Franz Joseph. He began secret negotiations with the Allies, hoping to peacefully end the First World War, but was unsuccessful. Despite Charles's efforts to preserve the empire by returning it to federalism and by championing Austro-Slavism, Austria-Hungary hurtled into 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 any participation" in government affairs, but did not abdicate. However, the Republic of German-Austria was proclaimed the following day, and in April 1919 the National Assembly formally dethroned the Habsburgs and banished Charles from German-Austria for life.
Charles spent the early part of his exile in Switzerland. He spent the remaining years of his life attempting to restore the monarchy. He made two attempts to reclaim the Hungarian throne in 1921, but failed due to the opposition of Hungary's Calvinist regent, Admiral 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. A deeply religious man, Charles was beatified by the Catholic Church in 2004, with October 21 as his feast day.
Early life

Charles was born on 17 August 1887, in the Castle of Persenbeug, in Lower Austria. His parents were Archduke Otto Franz of Austria and Princess Maria Josepha of Saxony. At the time, his grand-uncle Franz Joseph reigned as Emperor of Austria and King of Hungary. Upon the death of the Emperor's son Crown Prince Rudolph in 1889, Franz Joseph's brother (Charles' grandfather) Archduke Karl Ludwig became next in line to the Austro-Hungarian throne. However, his death in 1896 from typhoid made his eldest son, Archduke Franz Ferdinand, the new heir presumptive.
Archduke Charles was raised a devout Catholic. He spent his early years wherever his father's regiment happened to be stationed; later on, he lived in Vienna and Reichenau an der Rax. He was privately educated, but, contrary to the custom ruling in the imperial family, he attended a public gymnasium (the Schottengymnasium) for the sake of demonstrations in scientific subjects. On the conclusion of his studies at the gymnasium, he entered the army, spending the years from 1906 to 1908 as an officer chiefly in Prague, where he studied Law and Political Science concurrently with his military duties.
In 1907, he was declared of age, and Prince Zdenko von Lobkowitz was appointed as his chamberlain. During the next few years, he carried out his military duties in various Bohemian garrison towns. Charles's relations with his great-uncle were not intimate, and those with his uncle Franz Ferdinand were not cordial, with the differences between their wives increasing the existing tension between them. For these reasons, Charles, up to the time of the assassination of his uncle in 1914, obtained no insight into affairs of state, but led the life of a prince not destined for a high political position.
It was during one of these visits that Charles and Zita became reacquainted. Zita later recalled:
