Federico da Montefeltro, Italian condottiero (died 1482)

Federico da Montefeltro, also known as Federico III da Montefeltro KG, was one of the most successful mercenary captains (condottieri) of the Italian Renaissance, and lord of Urbino from 1444 until his death. A renowned intellectual humanist and civil leader in Urbino on top of his impeccable reputation for martial skill and honour, he commissioned the construction of a great library, perhaps the largest of Italy after the Vatican, with his own team of scribes in his scriptorium, and assembled around him a large humanistic court in the Ducal Palace, Urbino, designed by Luciano Laurana and Francesco di Giorgio Martini.
