Leonello d'Este, Marquis of Ferrara
Leonello was one of the three illegitimate sons of Niccolò d'Este III and Stella de' Tolomei. He received a military education under the condottiero Braccio da Montone, and was taught in letters by the humanist Guarino Veronese. In 1425, after the execution of his elder brother Ugo Aldobrandino, he remained the sole heir of Niccolò. In 1435 he married to Margherita Gonzaga and was renowned as legitimate son by Pope Martin V. Margherita, who died in 1439, gave birth to a child, Niccolò in 1438 (died in 1476). In 1441 he succeeded his father to his possession in northern Italy. In 1444 Leonello married to Mary of Aragon, illegitimate daughter of King Alfonso V of Naples.
Leonello was a skilled politician and was responsible of the construction of the first hospital of Ferrara. But he distinguished himself chiefly as a man of culture. Leon Battista Alberti wrote his De Re Aedificatoria under Leonello's commission, and at the Ferrarese court worked artists such as Pisanello, Iacopo Bellini, Giovanni da Oriolo, Andrea Mantegna, Piero della Francesca and the Netherlandish Rogier van der Weyden. His personal Breviary was sold in a fragmented state in 1958 by Baron LLangattock at Christies. It has since then been known as the LLanggattock breviary. Leaves from it is in the collections of museums and several private collections such as the Louvre in Paris. It was created under the artistic direction Giorgio d´Alemagna and painters like Matteo De Pasti and Jacopo Magnanimo contributed to it.
During his rule the University of Ferrara gained a European prestige.
Leonello died in 1450, at 43. He was succeeded by Borso d'Este, his father's illegitimate son.
