Joaquín Atanasio Pignatelli de Aragón y Moncayo

Joaquín Atanasio Pignatelli de Aragón y Moncayo (2 May 1724 - 12 May 1776), XVI Count of Fuentes and IV Marqués de Coscojuela, was a Hispano-Italian advisor and diplomat at the service of the Spanish monarchy.

Biography
He was born in the illustrious Pignatelli family, connected with the highest Neapolitan and Aragonese nobility. His father, Antonio Pignatelli of Aragon (1700-1746), was a second son of the IX Duke of Monteleón and Noya, and his mother, Francisca de Moncayo and Blanes (1700-1742), was Countess of Fuentes and Marquesa de Coscojuela. The young count was a Gentleman of the chamber of Ferdinand VI of Spain and Grandee of Spain 1st Class since 1751.

He was Ambassador in Turin from 1754 to 1758, in London from 1760 to 1762 and in Paris from 1763 to 1773. His stay in London was very difficult during the Seven Years' War.

During his embassy in France, he led the Spanish adhesion to the third Pacte de Famille and built a solid friendship with Étienne François, duc de Choiseul, Prime Minister of King Louis XV of France, who saw in Fuentes a "spirit suitable for business", of "broad genius", as well as a "very honest man and attached to our system." The Count was also a close friend of Jerónimo Grimaldi, although they ended up more distanced around 1775. After the fall of Choiseul in December 1770, Fuentes refused to pay respect to Madame du Barry, the new favorite of the French monarch and a former prostitute. This led to his forced departure from France in December 1772, being replaced by the Count of Aranda.

Back in Spain, he refused to exercise the presidency of the Council of Castile after the departure of Aranda, dedicating himself fully to his work as president of the Council of Orders (Consejo de Órdenes), which he had since 1768. Likewise, since 1763, he was a member of the State Council.

The XVI Count of Fuentes died in 1776, being buried in the Convent of San Hermenegildo in Madrid. He was a Knight in the Spanish Order of the Golden Fleece (1761) and the French Order of the Holy Spirit (1768).

Marriage and children
Fuentes married in 1741 with María Luisa de Gonzaga y Caraciolo, II Duchess of Solferino. From this union eight children were born, including :

After the death of his first wife, he remarried in 1775 with Mariana de Silva-Bazán y Sarmiento, widow of Francisco de Silva, 10th Duke of Huéscar and mother of María Cayetana de Silva. The Duchess Mariana originally was going to marry the eldest son of Fuentes, José María III Duke of Solferino, but he died before the marriage could be concluded. Fuentes died one year after this second marriage.
