Frederick (April 19, 1452 – November 9, 1504), sometimes called Frederick IV or Frederick of Aragon, was the last King of Naples from the Neapolitan branch of the House of Trastámara, ruling from 1496 to 1501. He was the second son of Ferdinand I, younger brother of Alfonso II, and uncle of Ferdinand II, his predecessor. A combination of King Louis XII of France and Frederick's famous cousin King Ferdinand II of Aragon had continued the claim of Louis's predecessor, King Charles VIII of France, to Naples and Sicily. In 1501 they deposed Frederick; Naples initially went to Louis, but by 1504 a falling-out led to Naples' seizure by Ferdinand, after which it remained part of the Spanish possessions until the end of the War of the Spanish Succession. Early life and education Born in Naples to Ferdinand I and his first wife, Isabella of Clermont, Princess of Taranto, he succeeded his childless nephew Ferdinand II after the latter's early death in 1496, at the age of 27. He was baptized on April 19, 1452, in Castel Capuano and his godfather was the Emperor Frederick III, who was then sent to Alfonso the Magnanimous on a diplomatic visit. His father ascended to the throne of Naples, upon the death of Alfonso the Magnanimous on June 27, 1458, and gave his son the best mentors: Andrea da Castelforte, Giovanni Elisio Calenzio, Girolamo Baldassare, and Offeriano Forti Service to King Ferrante In 1464 while residing in Taranto with his father, he was ordered to lead an escort for Ippolita Maria Sforza, eldest daughter of the Duke of Milan and fiancée of his brother Alfonso, from Milan to Naples. He left Naples on 18 March 1465 with 320 riders and learned while en route on March 30 about the death of his mother. He was received at Rome on April 2, 1465, by Pope Paul II who presented him with the golden rose. He then went to Siena and Florence, where he was received on April 17 by Lorenzo the Magnificent. He then journeyed to Milan, and stayed until June 7, ordered by the bride to return to Naples. He followed the same route when he was stopped by the Duke of Milan, who threatened to break up the wedding in Siena until diplomacy was opened up. He returned to Naples on 14 September.
