The Southern Netherlands and their Italian possessions were ceded to the Austrian Habsburgs and Savoy, Menorca and Gibraltar went to Britain while British merchants gained trading rights in the previously closed market of the Spanish Americas.
At this time, the key powerbroker at the Spanish court was Marie-Anne de la Trémoille, princesse des Ursins who dominated Phillip and his wife Maria Luisa of Savoy.
[6] By the end of 1715, Alberoni had been made a Duke and Grandee of Spain, a member of the King's council, Bishop of Málaga and Chief Minister of the Hispanic Monarchy.
These abolished internal custom-houses, promoted trade with the Americas, instituted a regular mail service to the colonies and reorganised state finances along lines established by the French economist Jean Orry.
Alberoni now attempted to offset British in the Mediterranean by sponsoring a Jacobite landing to divert their naval resources; he also sought to end the 1716 Anglo-French Alliance by using the Cellamare conspiracy to replace the current French Regent the Duke of Orleans with Phillip of Spain.
However, he failed to appreciate that Britain was now powerful enough to maintain naval superiority in the Mediterranean and the Atlantic while France declared war on Spain in December 1718 on the discovery of the Conspiracy.
On the death of Clement in 1721, Alberoni boldly appeared at the conclave, and took part in the election of Innocent XIII, after which he was for a short time imprisoned by the new pontiff on the demand of Spain on charges including sodomy (Elizabeth Charlotte of the Palatine noted in her diaries that he was a pederast).
[5] Benedict's successor, Clement XII (elected 1730), named him legate of Ravenna, where he erected the Porta Alberoni (1739), a magnificent gateway that formerly provided access to the city's dockyards, and has since been moved to the entrance of the Teatro Rasi.
[12] That same year, the strong and unwarrantable measures he adopted to subject the grand republic of San Marino to the papal states incurred the pope's displeasure and left a historical scar in that place's memory.
[13] He was soon replaced by another legate in 1740, and he retired to Piacenza, where in 1730 Clement XII appointed him administrator of the hospital of San Lazzaro, an institute founded in the medieval era for the benefit of lepers.
Interspersed in his official correspondence with Parma are requests for local delicacies triffole (truffles), salame, robiola cheeses, and agnolini (kind of pasta).
