The House of Albizzi was a prominent Florentine family during the late Middle Ages and the Renaissance. They were influential in politics and banking, often rivaling the more famous Medici family. The Albizzi were known for their support of the arts and their involvement in the governance of Florence. The family's power peaked in the 15th century, particularly under the leadership of Piero de' Albizzi. However, their influence waned after a series of political conflicts, leading to their eventual decline. The Albizzi legacy remains significant in the history of Florence and its cultural development.
