Don Pedro is remembered as the viceroy who tried without success to institute the Spanish Inquisition in Naples, in 1547. When the announcement of the Inquisition finally came in May 1547, the protest was immediate, turning violent very quickly. It was not a "popular" revolution, but rather a revolt by many of the landed nobility in and around Naples and Salerno, property owners who knew that the Inquisition had a reputation for confiscating the wealth and property of those whom it questioned. Additionally his Jewish chief financier Samuel Abravanel along with his wife Benvenida, may have had some influence on him, in regards to ending his aspirations of an Inquisition.
