Niccolò III d'Este (9 November 1383 – 26 December 1441) was Marquess of Ferrara from 1393 until his death. He was also a condottiero.
Biography
Born in Ferrara on 9 November 1383, Niccolo was the son of Alberto d'Este and Isotta Albaresani.[1] He inherited the rule of the city in 1393 when only 10 years old. As a minor he was guided by a Regency Council supported by the Republics of Venice, Florence and Bologna.
In 1395 the troops of the Regency Council were attacked at the Battle of Portomaggiore by Niccolò's relative Azzo X d'Este, a descendant of Obizzo II d'Este, who contested Niccolò's right to rule in Ferrara due to his illegitimate birth, even though Niccolò had been legitimated by his father. However, Azzo's mercenary forces were defeated in the battle and Azzo himself was taken prisoner and subsequently imprisoned by Astorre I Manfredi, commander of the Regency Council forces, thus removing the threat to Niccolò's rule.
In 1425 Niccolò had both his wife Parisina and his illegitimate son Ugo executed on charges of adultery, as well as decreeing that all women within his domains found to be guilty of adultery were to be put to death. He had to rescind this order once it was determined that this action would depopulate Ferrara.[3] In that year he was again commander-in-chief of the anti-Visconti league. In 1429 his illegitimate son was named heir of the Marquisate.
The role of Niccolò as a prestigious leader in Italy was confirmed when his city was chosen as the seat of a council in 1438.
Marriages and children
Niccolò had children with at least eleven different women.
