The Pazzi were a noble Florentine family in the Middle Ages. Their main trade during the fifteenth century was banking. In the aftermath of the Pazzi conspiracy in 1478, members of the family were banished from Florence and their property was confiscated; anyone named Pazzi had to take a new name.
Early in 1477, Francesco de' Pazzi, manager in Rome of the Pazzi bank, plotted with Girolamo Riario, nephew and protegé of the pope, Sixtus IV, and with Francesco Salviati, whom Sixtus had made archbishop of Pisa, to assassinate Lorenzo de' Medici and his brother Giuliano to oust the Medici family as rulers of Florence. Sixtus gave tacit support to the conspirators. The assassination attempt was made during mass in the Florence Cathedral on 26 April 1478. Giuliano was killed; Lorenzo was wounded but escaped. Salviati, with mercenaries from Perugia, tried but failed to take over the Palazzo della Signoria. Most of the conspirators were soon caught and summarily executed; five, including Francesco de' Pazzi, were hanged from the windows of the Palazzo della Signoria. Jacopo de' Pazzi, head of the family, escaped from Florence but was caught and brought back. He was tortured, then hanged from the Palazzo della Signoria next to the decomposing corpse of Salviati. He was buried at Santa Croce, but the body was dug up and thrown into a ditch. It was then dragged through the streets and propped up at the door of Palazzo Pazzi, where the rotting head was mockingly used as a door-knocker. From there it was thrown into the Arno; children fished it out and hung it from a willow tree, flogged it, and then threw it back into the river. The Pazzi were banished from Florence, and their lands and property confiscated. Their name and their coat of arms were perpetually suppressed. The name was erased from public registers, and all buildings and streets carrying it were renamed. Their shield with its dolphins was obliterated. Anyone named Pazzi had to take a new name; anyone married to a Pazzi was barred from public office. Guglielmo de' Pazzi, husband of Lorenzo's sister Bianca, was placed under house arrest, and later forbidden to enter the city; he went to live at Torre a Decima, near Pontassieve. After the overthrow of Piero de' Medici in 1494, members of the Pazzi family were able to return to Florence.
Pazzi Chapel
The Pazzi Chapel was designed by Filippo Brunelleschi. Construction began in 1442 in a cloister of the Franciscan church of Santa Croce. The High-Renaissance design is restrained and sober, using pietra serena and white plaster in geometric designs, generally unrelieved by colour, and capped with a hemispherical dome, completed after Brunelleschi's death according to his plans.
Palaces in Florence
Palazzo Pazzi : The main seat of the family, at canto Pazzi, where Borgo degli Albizi crosses via del Proconsolo, was commissioned by Jacopo de' Pazzi, and built circa 1462–72 to designs by Giuliano da Maiano. Above its traditionally rusticated ground floor of the yellow-ochre sandstone, it had a then-novel stuccoed first and second floor, with delicate designs in the windows influenced by Brunelleschi. The central court is surrounded on three sides by round-headed arcading, with circular bosses in the spandrels.
