Federico da Montefeltro
condottiere of the Italian Renaissance, and lord of Urbino

Federico da Montefeltro, also known as Federico III da Montefeltro (7 June 1422 – 10 September 1482), was one of the most successful mercenary captains (condottieri) of the Italian Renaissance. He became the lord of Urbino in 1444, and ruled the city as its duke from 1474 until his death. In addition to his considerable reputation for martial skill and honor, he was a renowned intellectual humanist and civic leader. Montefeltro commissioned the construction of a great library, perhaps the largest of Italy after the Vatican's, complete with a team of scribes in its scriptorium. He also assembled a large humanistic court in his Ducal Palace, designed by Luciano Laurana and Francesco di Giorgio Martini.
Biography
Federico was born in Castello di Petroia in Gubbio. Guidantonio da Montefeltro, lord of Urbino, Gubbio and Casteldurante, and Duke of Spoleto acknowledged Federico as his illegitimate son. Two years later he was legitimized by Pope Martin V, with the consent of Guidantonio's wife, Caterina Colonna, who was Martin's niece. However, there were persistent rumours that Federico was not Guidantonio's son, but his grandson. Guidantonio had an illegitimate daughter named Aura, who, in 1420, married Bernardino Ubaldini della Carda, a captain in Guidantonio's employ.
This brief starts where responsible research should: with the source description of “Federico da Montefeltro” as condottiere of the Italian Renaissance, and lord of Urbino. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as condottiere of the Italian Renaissance, and lord of Urbino. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q435501. The first chronological checks are 1422, 1482, 1444 and 1474.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
