Portrait of Charles VI (1685-1740), Holy Roman Emperor, King of Hungary and Bohemia, Archduke of Austria (1711-1740), Duke of Brabant, Limburg and Milan, Count of Flanders and Hainaut (1714-1740); King of Naples (1714-1735), King of Sicily (1720-1734)
Charles VI (1 October 1685 – 20 October 1740; German: Karl VI.) succeeded his elder brother, Joseph I, as Holy Roman Emperor, King of Bohemia, King of Hungary and Croatia, Serbia and Archduke of Austria in 1711. He unsuccessfully claimed the throne of Spain following the death of his relative, Charles II, in 1700. He married Elisabeth Christine of Brunswick-Wolfenbüttel, by whom he had his two children: Maria Theresa, the last Habsburg sovereign, and Maria Anna, Governess of the Austrian Netherlands. Archduke Charles the second son of the Emperor Leopold I and of his third wife, Princess Eleonor Magdalene of Neuburg, was born on 1 October 1685. His tutor was Anton Florian, Prince of Liechtenstein. Following the death of Charles II of Spain, in 1700, without any direct heir, Charles declared himself King of Spain—both were members of the House of Habsburg. The ensuing War of the Spanish Succession, which pitted France's candidate, Philip, Duke of Anjou, Louis XIV of France's grandson, against Austria's Charles, lasted for almost 14 years. Charles III, as he was known, disembarked in his kingdom in 1705, and stayed there for six years, only being able to exercise his rule in Catalonia, until the death of his brother, Joseph I, Holy Roman Emperor; he returned to Vienna to assume the imperial crown.
