In page Lucrezia Tornabuoni:

"

Lucrezia received many requests from citizens, which included appeals to end the exile or imprisonment of petitioners and to stop attacks by soldiers.[1] She was called upon to mediate disputes among others in the area, once ending a feud between two families that had gone on for twenty years.[2] Despite many Florentine problems having been resolved, conflict with the Medici continued. In October 1467, as part of a rivalry between Piero and Luca Pitti, there was an assassination attempt against Lucrezia and her son Giuliano.[3] Though the two survived, Giuliano was killed in 1478 as result of the Pazzi conspiracy against the Medici.[citation needed]
