viceroy (1722–1728), but upset the nobility (already reeling from imperial taxes) and the middle class with his pro-clerical stance. Althann's downfall came by attempting to establish a state bank (the Banco di San Carlo) with the intention of acquiring crown lands for the Austrian emperor. He infuriated both the nobility and middle class with this ill-conceived campaign, and after his expulsion Naples suffered several tumultuous years of famine and social unrest, with international problems preventing any attempt at administrative reform. It was with relief that the Spanish born Don Carlos ascended the throne of a reborn Kingdom of Naples in 1734. In 1759, he left to become King Charles III of Spain and was succeeded by his son Ferdinand, who was underage and so government was left to the regent Bernardo Tanucci. In the spirit of the Enlightenment, Tanucci attempted to establish a benevolent despotism by a series of reforms and weakening the power of traditional Neapolitan institutions. Ferdinand came of age in 1767, but had little interest in government and was largely dominated by his wife the Archduchess Maria Carolina, who disliked Tanucci's pro-Spanish stance and managed to replace him with Sir John Acton, an English emigre. When the French Revolution erupted, they allied with Austria and Britain against France. Sicily on the other hand experienced peaceful relations with Madrid, as the Spanish largely allowed the island to manage its own affairs. Since it was an important outpost in the Mediterranean as well as a significant trading partner of Spain, friendly ties were valued. After Sicily passed under Austrian rule in 1720, trouble erupted as Vienna stationed permanent garrisons of German-born troops on the island, provoking frequent and violent confrontations with the local populace. The corruption and backwardness of Sicilian society made it difficult to establish a working government, and much like Naples Sicily was forced to pay massive taxes and tribute to Vienna. However, Emperor Charles VI attempted to build up Sicily's economy by turning Messina and other locations into important ports so as to attract foreign commerce, as well as shore up the island's failing grain and silk industries. But the emperor could not offset an economic downturn that was beyond his control, and many of his projects proved unfeasible, ultimately causing a near-total economic meltdown. Charles had a tricky religious situation in Sicily where the king traditionally served as apostolic legate, which he sought to maintain
