Their rigorous quality control and the political role in the commune that the Arti Maggiori assumed were formative influences in the history of Florence, which became one of the richest cities of late medieval Europe.
The popolo minuto—skilled workers including weavers, spinners, dyers, boatmen, laborers, peddlers and others—despite constituting a majority of the population, were barred from forming guilds.
As elsewhere, the guilds of Florence protected its members from competition within the city by strangers and Florentine outsiders, guaranteed the quality of work through strict supervision of the workshops (botteghe), stipulated work hours, established markets and feast days, and provided public services to its members, and their wives, widows and children.
[5] The third scheduled list of guilds, finalizing their order of precedence for over a century appeared in a 1282 document known as the Foro Fiorentino, currently held at British Library.
They were also frequently members in the confraternity of St. Luke (Compagnia di San Luca)—which had been founded as early as 1349—although it was a separate entity from the guild system.
Annunziata, and sculptors, who had previously been members of a confraternity dedicated to St. Paul (Compagnia di San Paolo), also joined.
The statues of the Orsanmichele were a lavish joint, and highly competitive, effort, the Calimala were responsible for the Baptistry and paid for Ghiberti's famous doors, while the Lana were responsible for the cathedral itself, and paid for the cupola, the altar frontal and other works, and the Seta built and ran the Ospedale degli Innocenti.
[43] Given the prominent role of the guilds in the government of Florence, in 1427, Florentine greater nobles, led by Rinaldo degli Albizzi and Niccolò da Uzzano, attempted to introduce measures in the Signoria of Florence to reduce the number of minor guilds from fourteen to seven, thereby reducing the number of their representatives in the government.
All the Florentine guilds, major and minor, were abolished in 1770, by the decree of Leopold II, Holy Roman Emperor (as Grand Duke of Tuscany), assigning their functions to the single Florentine Chamber of Commerce, Art and Manufacture (Camera di Commercio, Arti e Manifatture), with the exception of the Arte dei Giudici e Notai (Judges & Notaries), which lingered on until it was finally abolished in 1777 by a new decree.
