The Peruzzi were bankers of Florence, among the leading families of the city in the 14th century, before the rise to prominence of the Medici. Their modest antecedents stretched back to the mid 11th century, according to the family's genealogist Luigi Passerini, but a restructuring of the Peruzzi company in 1300, with an infusion of outside capital, marked the start of a quarter-century of prosperity that brought the family consortium to the forefront of Florentine affairs.
