 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.In that year he was again commander-in-chief of the anti-Visconti league.
