The Albizzi family (Italian pronunciation: [ˈalbittsi]) was a patrician noble family and were the de facto leaders of an oligarchy of wealthy families that ruled Florence in the second half of the 14th century. They were at the center of the oligarchy from 1382, in the reaction that followed the Ciompi revolt, to the rise of the Medici in 1434.
One of the most powerful families of medieval Florence, the Albizi were active members of the wool guild Arte della Lana and were most prosperous between the 13th and 16th centuries. The Albizzi were known for their opposition to the Medici family and their significant role in the city's political and social life.
