Ferdinando Sanseverino, Prince of Salerno
He was one of the imperial leaders in the fourth war against Francis I of France and fought at the battle of Ceresole (1544). Returning to Naples, he clashed with the Spanish viceroy Pedro de Toledo, due to his opposition to the institution of Holy Inquisition tribunals in the Kingdom of Naples. He therefore moved to France at the court of King Henry II, embracing the Huguenot faith. His Italian fiefs were given to the Gonzaga family.
Ferdinando Sanseverino died at Avignon, in France, in 1568.
Main accomplishments 
He was an a passionate supporter of contemporary theatre, and had one built within his palace in Naples.
His refusal to accept the Inquisition inside his possession in Salerno created a break between him and the Spanish government in southern Italy. Mainly as a consequence of this, Fernando Sanseverino was forced to exile in France.
There, he organized a naval attack of French ships against Naples and Salerno, but it failed because the allied Turkish fleet didn't show up.
His legacy in the Principality of Salerno was to bring to the southern Italian city (and the surrounding area) the ideas of the Italian Renaissance. He brought to Salerno Torquato Tasso for some years.
