Note 26 page 9. “DUKE FEDERICO” DI MONTEFELTRO, (born 1422; died 1482), was a natural son of Count Guidantonio di Montefeltro, as appears from the act of legitimation issued by Pope Martin V and also from his father’s testament, by virtue whereof (as well as by the choice of the people) he succeeded his half-brother Count Oddantonio in 1444. In his boyhood he resided fifteen months as a hostage at Venice. Later he studied the theory and practice of war at the Mantuan court, and was trained in the humanities by the famous Vittorino da Feltre. In 1437 he married Gentile Brancaleone, who died childless in 1457. Nearly the whole of his life was spent in military service, as paid ally, now of one prince, now of another. In this capacity he became not only the most noted commander of his time, but always displayed perfect and exceptional fidelity to the causes that he undertook. In 1450 he lost an eye and suffered a fracture of the nose in a tournament; contemporary portraits represent his features in profile. In 1454 he began the construction of the great palace at Urbino. In 1460, at the suggestion of Francesco Sforza (whom he had aided to become Duke of Milan), he married the latter’s accomplished niece Battista Sforza, who bore him seven daughters and one son, Guidobaldo. In 1474 he was made Duke of Urbino and appointed Captain General of the Church by Pope Sixtus IV, and was unanimously elected a Knight of the Garter. He died of fever contracted during military operations in the malarial country near Ferrara. The vast sums spent by him on public buildings, art objects and books, and upon the maintenance of his splendid household, were not extorted from his subjects, but were received from foreign states in return for war service. Thus at the close of his life he drew a yearly stipend equivalent to about £330,000.
