Florence seized the Pazzi bank's property the day after the cathedral murder and ordered the family's name and arms erased forever

Jacopo de' Pazzi inherited his father Andrea's bank and became head of the family in 1464. In the 1457 tax survey he was one of only eight Florentines taxed between 50 and 100 florins. Pope Sixtus IV moved most papal business from the Medici bank to the Pazzi and borrowed from them to buy Imola. On Sunday 26 April 1478, during Mass in Florence Cathedral, conspirators attacked Lorenzo and Giuliano de' Medici. Giuliano was stabbed 19 times and died. Lorenzo escaped with a neck wound. Jacopo went to the Piazza della Signoria to rouse the crowd, was stoned, and fled. He was caught and hanged from a window of the Palazzo dei Priori on 28 April. Francesco de' Pazzi and Jacopo's nephew Renato were hanged too. Pazzi property was seized the day after the murder, before any sentence, and auctioned. A decree of 23 May 1478 ordered the Pazzi name and coat of arms erased forever and barred marriage into the family, on pain of exclusion from office. Surviving Pazzi men were jailed in the Volterra fortress. Jacopo was buried in the family tomb at Santa Croce, moved to ground by the city walls, then dug up by boys, dragged through the streets and thrown into the Arno. About two hundred people were executed. Lorenzo later released the surviving men on condition they live outside Florentine territory, and let Pazzi women marry.
