Ποιος παντρεύτηκε το Maria Carolina of Austria;

Maria Carolina of Austria (Maria Carolina Louise Josepha Johanna Antonia; 13 August 1752 – 8 September 1814) was Queen of Naples and Sicily as the wife of King Ferdinand IV and III, who later became King of the Two Sicilies. As de facto ruler of her husband's kingdoms, Maria Carolina oversaw the promulgation of many reforms, including the revocation of the ban on Freemasonry, the enlargement of the navy under her favorite, Sir John Acton, and the expulsion of Spanish influence. She was a proponent of enlightened absolutism until the advent of the French Revolution, when, in order to prevent its ideas gaining currency, she made Naples a police state.

Born an archduchess of Austria, the thirteenth child of Empress Maria Theresa and Holy Roman Emperor Francis I, Maria Carolina married Ferdinand as part of an Austrian alliance with Spain, of which Ferdinand's father was king. Following the birth of a male heir in 1775, Maria Carolina was admitted to the Privy Council. She dominated the Council until 1812, when she was sent back to Vienna. Like her mother, Maria Carolina arranged politically advantageous marriages for her children. Maria Carolina promoted Naples as a centre of the arts, patronising painters Jacob Philipp Hackert and Angelica Kauffman, and academics Gaetano Filangieri, Domenico Cirillo and Giuseppe Maria Galanti.

Maria Carolina, abhorring how the French treated their queen, her sister Marie Antoinette, allied Naples with Britain and Austria during the Napoleonic and French Revolutionary Wars. As a result of a failed Neapolitan invasion of French-occupied Rome, she fled to Sicily with her husband in December 1798. One month later, the Parthenopean Republic was declared, which repudiated Bourbon rule in Naples for six months. Deposed as Queen of Naples for a second time by French forces, in 1806, Maria Carolina died in Vienna in 1814, a year before her husband's restoration to Naples.

Maria Carolina was the last surviving child of Maria Theresa. She was also the last queen of Naples and Sicily before the unification of the two into the Kingdom of the Two Sicilies.

Προηγουμένως, από το 1759, είχε το αξίωμα του Βασιλιά της Νεαπόλεως (ως Φερδινάνδος Δ΄) και του Βασιλιά της Σικελίας (ως Φερδινάνδος Γ΄).
