The brothers were very wealthy, they had amassed large fortunes in commerce, and their houses extended for a considerable distance along that most fashionable of streets--the Borgo degli Albizzi. The Palazzo de' Pazzi doubtless was commenced by their grandfather, whose emblem--a ship--is among the architectural enrichments. The building was finished by their uncle, Giacopo--it is in the Via del Proconsolo. As bankers, the Pazzi were noted for their enterprise generally, and for their competition with the Medici in particular. They had agencies in all the chief cities of Europe and the East, but their reputation for avarice and sharp dealing was proverbial. Perhaps no family was quite so unpopular in Florence. Their traditions were aristocratic, whilst the Medici were champions of the people. This distinction was referred to by Madonna Alessandra Macinghi di Matteo degli Strozzi, in one of her letters to her son Filippo, at Naples. "I must bid you remember," she wrote, "that those who are upon the side of the Medici have always done well, whilst those who belong to the Pazzi, the contrary. So I pray you be on your guard." The growing importance of the Pazzi gave Piero and Lucrezia de' Medici much uneasiness, and it is quite certain that the marriage of their eldest daughter, Bianca--"Piero's tall daughter" as she was called--to the eldest of the three brothers, was a stroke of domestic policy by way of controlling the race for wealth and power. Lorenzo, very soon after his accession to the Headship of the State, "took the bull by the horns" and excluded the Pazzi from participation in public office. It was an extreme measure and not in accordance with his usual tact and circumspection, and of course it produced the greatest ill-will and resentment against him and his administration in every member of the proscribed family. The situation became greatly embittered when, in 1477, Lorenzo interfered in a law-suit which concerned the marriage dower and inheritance of Beatrice, the daughter of Giovanni Buonromeo. By Florentine law the daughter should have inherited the fortune without demur, under the express will of her father, who died intestate; but, at Lorenzo's command, the estate was passed on to Beatrice's cousin, Carlo Buonromeo, who was the winner of the second prize in Lorenzo's _Giostra_ of 1468. This decision was in direct opposition to Giuliano de' Medici's opinion, and he did all he could to reassure Giovanni de' Pazzi, Guglielmo's brother, and Beatrice's husband, of friendship and confidence. These were not the only incidents which followed one another at the parting of the ways of the two families, but the affair of Giovanni and Beatrice was resented with peculiar bitterness by all the Pazzi. "Hence arose," as Francesco de' Guicciardini has testified, "the wronging of the Pazzi!"
